Growing cannabis outdoors

Growing cannabis outdoors has been mans traditional method of growing his favourite recreational and medicinal herb for thousands of years.

Nature has provided cannabis with the adaptations and toughness needed to grow in many regions. Specialist selective breeding by the more professional cannabis seed suppliers has produced some truly outstanding varieties that will produce excellent cannabis in non-tropical northern European climates and even thousands of metres above sea level.

For those growers that don’t wish to grow cannabis indoors or in greenhouses, outdoor growing is a great and easy way to produce your stash. Growing cannabis outdoors with good quality feminized cannabis seed not only gives amazingly powerful weed but it also produces some of the best tasting cannabis with deep flavours and rich aromas.

What is important to know

How to choose an outdoor or garden growing spot?

For some people, outdoor growing means a secure and private part of their back garden or even a balcony. In some parts of the world this is too risky, so growers will choose a private and often remote spot in the countryside where they can grow their cannabis seeds.

Internet maps or local knowledge can be used to find private sun-facing locations. It’s very important that you put your plant in a spot with as many sun hours as possible. Also check if there is any moss growing near the spot you wish to grow. Moss is often an indication for an abundance of moisture, which can give you mold troubles during flowering.

Is your chosen grow location a windy spot or not? While some wind can help strengthen the stems and plant itself, too much wind will damage the plant, restrict growth rates and can cause them to die early. Not enough wind in an enclosed environment can also cause troubles with humidity because of still air, so choose wisely. Many growers like to have a few different grow locations, spreading the risk.

Selecting your location

Which type of soil do you have at your grow location? Is it possible to carry your own soil to the location? If the location is too remote to allow you to carry your own soil you will need to consider if you can work with the soil which is available. If the soil at your chosen grow location is just too sandy or has too much clay you may struggle to grow.

Is there water available nearby? If you are in a hot and dry climate it is always preferred to grow near a river, lake or stream. This allows easy access to water in hot conditions.

Can other people see your plants? Privacy is key if you want a successful harvest. When growing in your own garden it is recommended to keep plants low so neighbours or people that pass by can’t actually see the plants. It’s a risk you should avoid. If people can see cannabis plants, it’s usually just a matter of time before problems start. Often people call the police or steal the crop themselves.

SCROG grow technique

Growing autoflowers (which often stay around a metre in height) or using grow techniques like an outdoor SCROG to reduce the height of the plants are both popular with outdoor growers using their own garden. When growing guerrilla style, it is very important to protect your plants from the eye of unwanted visitors. Many that see your plants will wait until it is almost time to harvest and steal your plants before you can put your scissors to good use.

Those growing outdoors on their own land should be able to ensure that the plants receive all the water and nutrients that they need. This should guarantee the very best results assuming they originally invested in quality feminized cannabis seeds or autoflower seeds.

Those lucky enough to live in a Mediterranean climate with a private sun terrace are ideally placed for easy outdoor cannabis growing.

How do I select the perfect outdoor cannabis seed variety?

Step 1

Which climate are you in? Northern European climate, Mediterranean? Desert or Jungle? Select the right variety that is most suitable for your environment with a bloom time which works for your climate..

Step 2

Are you growing them in your own garden or guerrilla style? Some plants will be more suitable for guerrilla farming. Dutch Passion Hollands Hope for example was developed to be grown in the corn fields to become mature and ready to be cut faster than the corn that was grown by the farmer.

Other Dutch Passion outdoor cannabis seed varieties, like Frisian Dew, Passion #1 and Durban Poison are real outdoor champions. They will do well both in guerrilla style grows as well as the garden, because they have vigorous growth and better resistance to mould and fungus.

Autoflowers need to be checked more regularly because of their short, accelerated growing cycle. They benefit from a little more protection more than traditional photoperiod strains, which have 2-4 months just for vegetive growth. Where possible, regular visits to your outdoor autoflowers allows you to keep on top of small pest outbreaks, nutrient & water issues etc.

Step 3

What type of plant are you looking for? A big yielding plant? A certain type of high? Type of flavor? Does the strain need to be short? Will it cause visibility problems if the plant gets too tall? You may wish to keep your plant below a certain height to prevent others from seeing it.

If so, don’t grow Sativa dominant fem varieties, choose Indica’s, Indica-dominant hybrids or grow strictly autoflowers if you want them below 1.50 – 1.75m. Choose wisely. A stretchy Sativa variety can easily reach 3m tall and will be visible from some distance.

When growing cannabis outdoors think carefully about the variety. Not all strains are suited to outdoors, so read the reviews carefully and choose a good seed supplier. The best outdoor strains for Northern-Western Europe (or similar climates) were often developed over a period of several years, selectively breeding those offspring that displayed the best suitability to outdoor conditions as well as retaining premium potency levels.

This is a full time job that requires an expert ability not just to create premium outdoor strains but also to stabilise them. Some good examples are the best selling outdoor varieties Frisian Dew®. Hollands Hope®, Passion#1® and Durban Poison®.

You can also choose one of the autoflowers, which are all suitable for growing outdoors during spring and summer.

When can I start growing cannabis outdoors?

It’s important to place your cannabis plants outside after the last frost. That’s because young seedlings struggle to survive if planted out too early. Starting around the middle of May is generally a safe option for northern European growers. The outdoor grower typically grows from April/May to October in the northern hemisphere.

Outdoor growers often germinate the cannabis seeds indoors and give their plants a head-start by growing them indoors under lights for a few weeks with an 18/6 or 20/4 light schedule. Outdoor cannabis growers often acclimatise their plants to outdoor temperatures gradually before permanently planting them outdoors. This allow the plants to adapt slowly from indoor conditions to outdoor life.

It’s also possible for northern European growers to start growing cannabis outdoors around the beginning of April with the help of a greenhouse or polytunnel. This will help protect the plants from the worst of the early season weather. In mediterranean climates the growing season is longer and more varieties can be successfully grown. Growers in the southern hemisphere often grow cannabis outdoors from October to April.

When can I harvest my outdoor cannabis?

Harvest times given on this website are for the Dutch climate and latitude. Most outdoor varieties you can find in the ‘Dutch Outdoor‘ selection on our website. All our outdoor feminized cannabis seed varieties are carefully selected, developed and bred in Holland. This makes them very suitable to grow in the Dutch climate (or similar), which can be very wet and cold from time to time.

Important for these varieties is that they finish flowering early in the year. Good examples are varieties like Frisian Dew®. Hollands Hope®, Passion#1® and Durban Poison®. You can harvest these outdoor varieties from around the end of September until late October. Because the genetics of these outdoor varieties have been bred to handle bad weather conditions, in combination with an early finish, they are perfect for outdoor growing in Northern latitudes.

Many outdoor cannabis growers with short growing seasons grow feminized autoflower seeds. These grow from seed to harvest in around 100 days outdoors, the shorter life cycle of the autoflowering cannabis varieties makes them a good choice for outdoor growers.

With autoflower seeds it is possible to grow 2 successive crops in one outdoor growing season, (or even 3 in warm sunny Mediterranean conditions) but you need to prepare and time it well.

Can I grow ‘indoor’ cannabis seed varieties outdoor as well?

All “indoor” and “outdoor” cannabis seed varieties can be grown outdoors at warmer latitudes. For this reason, the harvest time under natural light is also given for all the “indoor” varieties.

Greenhouse seed varieties and indoor varieties can be grown outdoors in Central and Southern Europe with very good results. In more Northern latitudes (Scandinavia, UK etc) only the outdoor varieties that are harvested early can be grown outdoors. Frisian Dew is particularly well regarded by northern European growers.

Growing cannabis outdoors with the best autoflower seeds

Many growers at extreme northern/southern latitudes find that autoflower seeds are the best option for a short growing season. Many dedicated ‘Indoor’ varieties simply finish flowering much too late. This increases the risk of bad weather conditions destroying your harvest.

A Haze variety which would finish outdoor bloom in November may be possible to grow in southern Spain, but it would be unsuitable for central or northern Europe. Most “outdoor” varieties cannot be grown indoors as well, unless mentioned in the variety description.

Grow in pots or directly into the soil?

Those growing on their own land may have the option of growing the cannabis plants in plant pots or rooting them directly into the soil. Plant pots have the advantage of being portable but will need regular watering in hot weather. Putting your plant in a pot also allows the user to place and relocate the plant into a sunny spot when needed.

The experienced grower will often avoid ‘black’ plant containers which get very hot in direct sunlight. They will also avoid putting plant pots directly onto a hot surface (e.g. tiled terrace) which will stress the roots.

Bigger pots for oudoor grows

When growing outdoors in pots it is recommended to use bigger pots than usual. For photoperiod plants you can use pots from 50litres upwards to a few hundred litres if you want to grow Californian style monsters.

For outdoor autoflowers use anywhere between 20 – 50 litre containers. The longer the autoflowers grow, the bigger the pot needs to be. The extra soil in the pot will create a bufferzone to prevent the soil from completely drying out. Even though most autoflowers will not fill the 50L pot completely with roots, the pot itself will hold more moisture than a 10L pot. This increases your chance of success and reduces the chance of plants struggling due to lack of water. Make sure to use a well-aerated pot like Autopot, Rootpouch or Smartpot for the best results.

Growing in pots gives you more control (as described above) and provides the plants with more air/oxygen at the root zone which stimulates faster and healthier growth.

Furthermore rain water will flush plants that are grown in pots more than plants which are rooted into the ground. This gives the grower a better control of nutrients when growing plants in containers.

What should I look for when growing outside? (Guerrilla cannabis grow)

One of the most important factors for the outdoor grower is to correctly identify and prepare the site. Your cannabis seeds are valuable, so it’s well worth taking extra time to check and evaluate plenty of possible grow sites.

The ideal grow site should get unrestricted sun for as much of the day as possible. Protection from strong winds will also shield your crop. A grow site will often benefit from shelter; a small earth bank, a fallen tree stem or thick bushes can not only protect the plant from prevailing winds but it may also protect the plant from animals and unwelcome human attention.

Having a close source of water, such as a nearby stream can make it easy to get water to your crop during hot weather.

How do I pick a private safe spot for my outdoor grow?

Those growing outdoors may not always be able to visit the plants regularly so a grow spot has to be chosen which is private, sunny and with some protection from animals such as rabbits and deer that will eat the cannabis. Some growers surround their secret grow spot with branches and undergrowth to conceal the crop and deter grazing animals.

Other growers deliberately plant thorny plants (blackberry plants etc) around their grow area to provide lasting and effective protection. This technique usually involves systematically surrounding the grow patch with a thick, tall and impenetrable barrier to humans and animals

How do I protect my outdoor guerrilla plant?

Those growing outdoors may not always be able to visit the plants regularly so a grow spot has to be chosen which is private, sunny and with some protection from animals such as rabbits and deer that will happily munch the plants if not kept away.

Some growers surround their secret cannabis grow spot with branches and undergrowth to conceal the crop and deter grazing animals. Other growers deliberately plant thorny plants (blackberry plants etc) around their grow area to provide lasting and effective protection. This technique usually involves systematically surrounding the grow patch with a thick, tall and impenetrable barrier to humans and animals. When done properly there is absolutely no way that anyone could guess cannabis plants are growing nearby.

Often the only way into the centre of such a grow is by crawling along the ground through a single secure route that can be easily covered and hidden.

A good tip for outdoor growers is to surround the plants with chicken wire, or a similar green garden wire. This helps keep animals away from the young and vulnerable plants. Once the plants are larger they become more difficult to be eaten.

How do I prepare the soil for the cannabis seeds?

Many outdoor growers will use organic fertilisers such as bat guano, worm castings, bloodmeal, bonemeal etc to improve soil condition before the grow starts, perhaps digging in plenty of compost as well. More proficient outdoor growers will test the soil when preparing the site and fertilise it accordingly. Professional soil testing kits can be bought from garden centres which will indicate the soil type, the pH and factors such as sand content, loam and clay content etc. There is no ‘perfect’ soil for growing in and different varieties will often perform well in a range of conditions so long as nutrients are present, drainage is good and pH is within 5.8-6.5.

Growing cannabis seeds outdoors organically

These days many outdoor growers often have a preference to grow organically, avoiding chemical pesticides, additive and fertilisers where possible. BioTabs are a nutrient company who specialise in making grow additives from entirely natural materials. A full range of products are available. One of the most popular products are the palm-sized general fertilizer tablets.

BioTabs take plant root health very seriously, the products contain beneficial bacteria which create a healthy root zone as well as supplying all the required minerals for healthy plant growth. Just place a few of the tablets in and around the root zone.

Many growers dig a hole somewhere between 5-100 litres. Often they will fill this with a high quality pre-made soil from the garden centre/grow-shop. The plant (and supplementary BioTab nutrient tablets) are just placed in the hole and then watered.

For most growers it isn’t necessary to test soil pH, but professional growers with large crops and a business to run will take soil quality very seriously.

Helpful tips for preparing the soil

Visits to the grow spot will often involve checking the plants for pests and treating them accordingly. In dry weather water may need bringing to the plants. Some outdoor growers transport their own soil to the grow site, often it will have been pre-enriched with e.g. worm castings and perhaps water absorbent gel crystals will have been added.

Water absorbent gel crystals can be bought in many garden centres and absorb excess moisture swelling into large water retaining gel particles. These then slowly release the water during dryer times. They allow plants to thrive with additional water reserves for their roots even in drought conditions.

It is crucial to keep the soil in the best condition possible for the plants. This allows the plants to grow in optimized conditions, and gives you the best chance of producing the best results from your cannabis seeds. Some growers mix coco fibre in with the soil, this increases aeration and is particularly useful if the soil is heavy with a high clay content.

As previously mentioned, BioTabs produce compressed nutrient tablets which slowly release all necessary nutrients into the soil throughout the full grow cycle of the cannabis plant. BioGrow are another proven nutrient provider for outdoor growers. As well as releasing nutrients, BioTabs also produce a healthy microbiological root zone for the plants.

Check the soil doesn’t become too dry during summer. Your plants will need moist nutritious soil to reach their full potential. Although it isn’t absolutely critical to offer your outdoor plants supplementary nutrition, many experienced outdoor growers like to monitor their plants through the complete grow cycle and will add extra nutrition to the soil when they feel it necessary. The best quality outdoor cannabis seeds will produce exceptional results in optimized soil/environmental conditions.

Growing cannabis in the canopy of a tree

Some growers prefer the seclusion remote forests, woods or mountains for complete peace-of-mind and security. A new technique is to grow cannabis plants in large soil-filled sacks that have been hoisted into the tree canopy.

This technique allows growers to choose locations that may be closer to home since the plants are completely invisible to people passing nearby. Plants grown in this way benefit from all-day sunlight and can be grown relatively close to cities and villages without raising suspicion. Just make sure that the sack is securely fixed in place.

Please note that this method does not allow a grower to keep close track of their grow and comes with certain risks of getting your plants where they need to be.

Outdoor growing can be challenging but fun

Sometimes the hardest part of outdoor growing is selecting the right location and preparing it for the cannabis plants/seeds. Often the outdoor grower will have several different grow locations and accepts that losing the occasional plant is an occupational hazard.

Once the spot is ready it will often be used for many years of harvesting by the outdoor cannabis grower. Outdoor growing is challenging but fun, it may require ingenious thinking and professional preparation but when done correctly the outdoor grower can experience the thrill and satisfaction from harvesting all his herbal supplies free of charge, the way nature intended.

A well planned outdoor grow deserves fully proven genetics. Dutch Passion have been relied on since the 1980’s for the best outdoor cannabis seeds. With numerous cannabis cups over many decades, Dutch Passion have earned their reputation for their high quality outdoor cannabis seeds. You can expect heavy yields of top strength cannabis from varieties which are easy to grow and less susceptible to disease and pests.

How to Grow Marijuana Outdoors – Growing Weed

With marijuana being legalized or decriminalized in a number of US states and other countries around the world, there are many people who wish to grow their own weed. Indoor hydroponic systems are becoming easier to master and can produce some very satisfying yields, but there is something about letting cannabis plants flourish in an outdoor environment that can be incredibly rewarding. Left to grow naturally marijuana can produce even better yields than indoors and flavors are often said to be more intricate. For those people who prefer things more natural, it is also possible to grow marijuana outdoors in a 100% organic way.

So, for all you budding guerilla gardeners out there, this guide will cover the basics, giving you all the information you need to start growing your own top grade weed outdoors.

Geographic location

Lots of people think that you require a hot, sub tropical climate to grow marijuana outdoors. This is not the case. If you think about the high areas of Central Asia where cannabis originally comes from, the climate can be harsh and often cold at altitude. There are also cannabis strains bred specifically for outdoors in colder climates, such as Early Skunk. Strain selection is a crucial part of a successful outdoor grow, read about it more in the section about cannabis strain selection. With some care and planning you can grow cannabis outdoors from the hottest tropical regions to as far north as Alaska or Scandinavia.

Site Selection

Selecting the right site for your outdoor marijuana grow is of the utmost importance. When considering a potential site you will need to think about the basic requirements of your marijuana plants as well as how you are going to get to and from the site and whether the plants are going to be hidden from view. We have a full section on outdoor growing site selection.

Stealth

Even though you may live in a place where it is not illegal to grow marijuana outdoors, weather you are growing in your backyard or elsewhere stealth is still one of your primary concerns. Growing marijuana is still a contentious issue to many people, possibly including your neighbors, and some people just don’t like it. There’s always the danger of theft too. Any smoker who happened to stumble upon your lovely ripe plants while out walking in the woods or seeing it over your back fence one day might be likely to help himself to some. If you are growing in your garden, after you consider the best locations in terms of sunlight start thinking how you will conceal the plants. Usually the best way to do this is with other plants such as tomatoes as they grow quickly like your weed will. If you are growing in the woods consider locations that are far away from tracks or paths used by walkers. You might need to get your hiking boots on and head across country, away from people. Dog walkers and hikers get everywhere so look out for signs of their passing and look for places that they might think too awkward to get to. If you live somewhere where there is dense ground cover, it is sometimes possible to worm your way under the foliage to clearings within. Using ‘fox holes’ like this can be an excellent idea as their entrances are easily concealed with branches and leaves. Choosing a site near a stream or brook means that it may be accessed via the water. This is a good way to avoid leaving paths or tracks that clearly show to others where you have been. Farmer’s fields can be useful if you know the area well and know which bits are regularly visited and which aren’t. Field margins are often overlooked and can provide good locations for outdoor grows. However, be careful if there is any chemical spraying going on in the area. Industrial sites should not be ignored either, especially derelict or run down sites. Sometimes these locations can go for years without being visited at all. They often contain hidden away bits of scrap land that are all but forgotten by everybody. There is a more extensive guide to picking a spot in the woods in our guerilla grow guide.

Sunlight

Once you are satisfied with the security of your chosen site, you will have to then consider if it offers all of your plants’ natural requirements. The first of these is sunlight. The more sunlight your cannabis plant gets, the more it will grow. As an absolute minimum, cannabis plants require around six hours of sunlight per day. More would be much better. When selecting a site try to envisage or calculate with a compass how much light it will get throughout the day, and throughout the summer. Note where the sun rises and sets and imagine the arc that it makes, both now and at high summer and into fall. Will your plants get enough light throughout their entire life cycle? Watch out for surrounding plants and if they will shade out your babies now and in the future when they grow, can you cut them back. Remember, if you are checking a site out in spring, there will be a whole lot more foliage come the summer.

Water

If you live in a climate with adequate rainfall then water shouldn’t be too much of a problem. However, if you live somewhere that experiences long dry seasons then a good supply of water is crucial. Near to a river or stream is ideal, but remember that they may flood in spring or autumn. Is there a strand line that shows you where the high water has been? If you are able to, situate a water tank nearby on a slow drip or try stashing some large containers of water nearby so that you can water the plants easily in times of drought. Be sure to keep an eye on the weather forecasts during your grow. You should know if any adverse weather like a late or early cold snap or long days of hot weather – know beforehand and not get caught out by surprise to find your babies dead.

Check the soil of the site first. Good soil should compact when you squeeze it, be dark brown in color and but should break apart again with only a small amount of pressure. You should know good soil when you see it really; if you have any doubts take a look online for what it should look like. You need the soil to be well drained, try to avoid places with patches of standing water, clay or rocky soil. Cannabis does not like being waterlogged. Look at what else is already growing at the site. If there are plenty of grasses, weeds and nettles then chances are that the location is already blessed with decent soil and water. A soil pH meter is relatively cheap to buy. This is not essential, but the more effort you put in now, the better your weed will be. Cannabis likes a very slightly acidic soil, pH 5.5 -6.5 is ideal. You will be very lucky if you find the ideal soil, but don’t despair. It is easy to improve soil, try digging in a mix of some potting compost, well rotted manure and Perlite or vermiculite to improve drainage and aeration. Cannabis roots need plenty of oxygen so try to lighten heavy, compacted soils. Having selected your site, clear the area completely of weeds. When your plants are young they can easily be swallowed up by indigenous plants so you need to give them a head start. If you are able, dig a hole out for each plant approximately two feet deep and two feet in diameter and line the base with two inches of gravel to enable good drainage. Now fill the rest of the hole with your prepared soil/compost mix. This is a lot of work and to fill it with good potting mix and gravel will take plenty of trips with a heavy backpack. Your site is now ready to take your plants but you still have some more decisions to make.

Strain selection

Indica or Sativa

As stated earlier, the cannabis strain that you choose is going to be crucial to the success of your grow. This is an area where it is worth doing a bit of research. If you live somewhere frost free with an incredibly long growing season you can pretty much choose whatever strain you want. This includes nearly all the indicas and the old school sativas, like the Hazes which have a long flowering period but which can produce immense yields. Climates which are less tropical, but otherwise sunny, like the Mediterranean or the southern states, have less choice. However, you can still grow most indicas and, with modern breeding techniques, you can grow some hybridized sativas such as Silver Haze #9, which is a Haze with a shorter flowering cycle.

Those millions of us without the luxury of such an environment, who live in colder, damper environments, need to be a bit pickier. Although it is mostly indicas that can be grown in these environments, again, some modern hybrid strains allow you to get sativas such as Bangi Haze. Or, you could just work with what you have and select a good indica strain such as Sensi Star, or Holland’s Hope which has been specifically bred for growing outdoors in northern climates.

Autoflowering cannabis strains

The ever increasing amount of autoflowering cannabis strains available is of great interest to the outdoor cannabis grower. Their fast finishing time ensures missing any untimely frosts and their diminutive stature makes stealth much easier. Auto strains get their autoflowering qualities from Cannabis ruderalis genes and many of them are suitable for growing outdoors in cooler conditions. Consider Auto Frisian Dew or Snow Ryder.

Bag seeds

Of course, we are not all granted the luxury of being able to pick and choose which strains we grow. Lots and lots of people have great success with growing seeds found in bags of purchased weed. You might not even know what type of cannabis it is, but it’s always worth giving it a go. Nothing ventured – nothing gained. If you do grow bag weed try and identify it as soon as you can. If it grows with thin fingered, light green leaves and long internode lengths it could be sativa dominant and take longer to finish flowering. Dark, thick fingered leaves and a short, squat structure can indicate an indica dominant plant which should flower more quickly.

Clones or seeds?

If you have access to clones then this is nearly always the best decision to make. Clones have guaranteed genetic traits, particularly if you only require female plants. They also give you a head start over seeds by being more developed with existing leaves and a root system. On the other hand, buying seeds from a shop or online resource gives you much more choice over which strain you grow. Buy your cannabis seeds from a reputable source and try to buy the best you can afford. If you do use clones, be sure treat them with care and make sure their roots are properly developed before planting them out.

Germination

If you are growing your plants from seed you have the choice of either germinating them at home and then planting them out, or sowing them directly in their final location. The choice is yours and each has its benefits. Germinating them at home gives you more control over the very delicate early stages whereas sowing them directly avoids possible damage when transporting and transplanting them. There are a number of ways of germinating cannabis seeds. Everyone has their own way of doing it. Perhaps the simplest way is to place your seeds between layers of moist (not soaking) tissue paper and put them somewhere warm and dark. Your seeds should crack their shells in just a few days. Let your seedlings develop a small web of roots before potting them on. When they have, get a small pot full of fine potting compost and make a hole in it with the end of a pencil. Carefully place your young seedling into it, making sure that the roots go down into the hole. Sometimes the roots become woven into the fabric of the tissue paper. If this is the case, do not risk damaging them by pulling them apart. Simply cut a small circle out of the paper, around the roots, and put the plant in the pot with the paper still attached. Some people just plant the seeds directly into a small pot and let them sprout naturally. If you do this, try soaking the seed for 24 hours before planting to soften up the shell. If you are going to sow your seeds directly into the ground at your chosen site, simply make a tiny hole in your prepared soil, about ¼” to ½” deep, and pop the seed in it, pointy side up. Make sure that the soil is watered and clear all other plants from the area to give your baby a chance to get going.

Planting

If you have started your seed off at home, which is recommended, you will want to plant it out when it is around six inches tall with three or four internodes. Make a hole in your prepared soil that will accommodate the whole contents of the pot without disturbing the roots. Remove the cannabis plant from the pot by turning it upside down and tapping the base. Now place the root ball in the hole and firm it in. Make sure you give it a good drink at this point. Once established your seedlings will soon enter a vigorous vegetative growth stage. From such fragile beginnings plants quickly become full and robust. Unlike growing marijuana indoors, you have no control over the duration of the vegetative growth stage and over the course of a summer plants can become huge. It is a good idea during this phase to feed your plants well with some quality, nitrogen rich, fertilizer. Your cannabis plant is now growing in your carefully selected site. If stealth is important to you, you will want to keep visits to the site to a minimum. If it is safe to visit your site then keep looking and clearing away any plants that begin to encroach on your babies. If you want to grow only female cannabis plants there is one visit that you will not be able to avoid. At some time, probably between the fifth and sixth week of vegetative growth, your plants will display their gender and you will need to act accordingly.

Sexing Your Marijuana Plants

Why sex your marijuana plants?

Whether you remove the males from your grow or not depends on whether you want seeds or sensimilla. Sensimilla literally means ‘without seeds’ and is obtained from female plants that have not been pollinated by males. Instead of putting their energy into seed production, these ‘virgin’ plants put all their resources into THC production and produce weed that is more potent and has no seeds. Of course, you might want seeds to provide for next year’s harvest. If this is the case then you do not need to worry about removing males. Weed with seeds is fine to smoke too. However, if you are like most people you will want to remove those pesky males as soon as possible. To do this you will need to sex your cannabis plants.

How to Sex Marijuana Plants

Before we start talking about preflowers it is worth mentioning that cannabis plants often exhibit their gender before the appearance of preflowers. Male cannabis plants tend to be taller and leggier than females with sparser foliage. Males also have fewer leaf nodes and are often lighter in color than females. If you have plants that fit these descriptions chances are that they are males. The 100% sure way of sexing your plants is by the appearance of preflowers. Sexing is often considered to be one of the trickiest parts of growing your own marijuana, like a lot of things however it is easier than you think and will become easier as you gain more experience. Usually the preflowers will start to show between the fifth and sixth week and appear around the fifth or sixth nodes. Ideally you will need a magnifying glass to get a proper look at them. Female preflowers are small with delicate white hairs protruding. Male preflowers appear as small bumps right on the node. These bumps are the beginning of the male pollen sac. If you have positively identified male plants at your site and you want to produce seedless weed, remove them immediately.

Common Problems

Growing marijuana outdoors means that your plants are open to all the pests and problems associated with outdoor growth. A lot of problems are specific to your locality but there are two major problems that affect marijuana growers everywhere.

Bud Rot

Bud rot, AKA grey mold, is properly known as Botrytis cinerea and is a fast spreading necrotic fungis that can destroy a whole cannabis garden in just a matter of days. Most commonly bud rot affects plants during the flowering phase when kolas get big and fat and damp. The first sign is often when a small leaf sticking out from the kola begins to wither and die. A small, localized clump of mold will quickly appear at this site and this can very quickly infect the whole plant. Left untreated bud rot will turn all your flowers to slime. The best way to treat bud rot is prevention. Try to ensure that your growing area is well ventilated with good air circulation. Some people like to spray their plants with an organic fungicide as a matter of course, whereas other seek to avoid this. If you do spray, only do so before the flowers have began to form. Smoking fungicide is dangerous and to be avoided at all costs. If you find bud rot on one of your plants you need to act immediately. Carefully remove the affected section of bud from at least an inch below the mold with a pair of sterilized scissors. Be very gentle with it, shaking it about will spread the millions of spores to other parts of the plant. Place the infected material in a plastic bag and remove it from the site completely. You will now need to check your plants daily, looking carefully for further signs of mold. Try bending the kolas so that you can see the stem underneath. This is where the bud rot starts. If you see any signs of mold remove the affected part of the plant immediately. Because bud rot tends to affect plants during the later part of the flowering period it is sometimes worth cropping the plant early to avoid further contamination. If you only have a week or so to go before your planned harvest date you might want to consider this.

Spider mites

The other universal problem associated with growing weed outdoors is spider mites. These tiny arachnids generally live on the underside of leaves and puncture the leaf cells to feed. They can cause a great deal of damage and an infestation can quickly get out of hand. Small brown and yellow dots and a scorched look to leaves is the first sign that you may have a spider mite infestation. If this is the case, place a piece of white paper underneath the leaf and tap the leaf gently. Are there small, slow moving specks on it? If so, chances are you have spider mites.
