how big can autoflowers get

Sure, some growers grow autos just like photoperiod plants by transplanting them not once by twice! However, they are experienced growers that have attained success after several failures.

Containers must be proportional to the size of the plant. For example, medium-sized plants require at least 5–7 gallon containers whereas big plants need pots that are more than 11 gallons. Remember, the type of container you choose plays a major role as well. Autoflowers love aerated soil that drains very well, so use breathable containers like fabric pots that allow maximum drainage.

Most autoflowers start flowering in the third or fourth week, so start training only if the plants grow fast and remain healthy enough to be trained. If you’re unsure, it’s okay to not train the plants at all.

Most people assume that autoflowers produce small yields, but they can’t be further from the truth. Get this straight — autoflowers can not only produce humongous yields, but the fact that they do so within 2 months isn’t a small feat! But, you gotta follow a small rulebook, so here are 7 tips and tricks to maximize yields in autoflowers if you’re struggling to get the best out of them.

It’s also important to do some research to purchase autoflowering seeds of the highest quality. You can do everything right but it may all be for naught if the strains aren’t meant to produce high yields. For example, Fastbuds catalog shows you seeds ranging from XXL to L yield category, and you can choose anything depending on the space available.

Fabric pots, also known as “Smart Pots”, are plant containers made from vegetable matter, usually coconut coir. When the roots reach the sides of the pot, they become trapped in the porous fabric and naturally trimmed by the outside air. This “air pruning” even encourages root growth and prevents ring roots (that is, they do not outgrow their pots). Another advantage of fabric pots is that their porous structure makes it almost impossible to overwater your plants. These are inexpensive, and you can easily poke holes in them. They are available in many sizes and colors. However, they are not very robust and can split, and they do not protect roots from extreme temperatures.

Unless you know your cannabis very well and can accurately estimate how much water each plant will need, it is best to buy a container with holes/perforations in the bottom. In fact, you should still make your life easier and opt for holes, even if you know exactly how much they need. This allows excess water to drain and oxygen to flow through the growing medium, reducing the chance of root rot – a problem that occurs if the soil is left too wet for too long. Don’t over water – stick your little finger an inch into the soil to see how moist it is before watering.

Fabric containers

The main disadvantage of fabric pots is that they dry out faster than ordinary pots. You will need to water them more often or use larger pots with more soil to keep this from happening. Fabric pots are also less robust than standard planters. Since they are more like bags, they are more likely to tip over.

Another consideration when growing outdoors is to opt for white pots, as they store less heat than black or gray containers.

Clay pots, for example, will remove moisture from your soil, which is why you need to water more frequently. Metal containers can rust, store too much heat and even cause contamination. Wooden containers are excellent for growing weed, but they are often very large and expensive. The most common choice are plastic pots. These are inexpensive, durable, and clean. They’re nothing special, but they’ll do the job and do it well.

The typical auto-flower plant size is from 7 to 20 inches (17cm to 50cm) but it may be smaller if the conditions are harsh or exactly the opposite if they are perfect.

Here are the most common environmental factors that can influence your plants size the most:

Pot size

Pot size is very important aspect for your autoflowering plants size and if the pot is too small then your plant will become root bound and it will stun the growth. For regular plants the rule of thumb is to get a gallon (3,7 liters) of dirt per foot (30,4 cm) of the plant height. That means if you are planning to grow your plant 60 centimeters then you need at least a 7 liter pot. In general you can grow your autoflower plant to its fullest potential in 1 to 3 gallon (3,7 to 11.1liter) pots but be sure to read more about pot sizes before getting the right one.

The light cycle also affects these day neutral plants and if the majority of the day it is dark in the growing room then your plants will also stretch and won’t be able to produce dense and huge buds, but if they get the proper amount of light (18 to 24 hours a day) then they will grow like real weeds and you will be able too see height changes every single day!

Basically all of these previously mentioned conditions can affect the plant size but some may affect it more than others and there are also those SUPER autoflowers that grow huge so be careful what strain you get!
