Autoflowering strains provide fantastic results in little time, often surging from seed to harvest in as little as 8 weeks. Both beginner and advanced growers will have a fun and easy time raising these varieties.
Many growers elect to cultivate autoflowers because of their speedy growing rate. Their hardy genetics and forgiving nature also make them easier to grow and therefore more beginner-friendly.
HOW LONG DO AUTOFLOWERS TAKE FROM SEED TO HARVEST?
Follow the fail-safe week-by-week grow guide below for a quick and easy route to harvest time. We cover all of the parameters and variables you need to consider—at the correct times—to ensure your plants remain healthy, vigorous, and productive.
Autoflowering strains typically move from seed to harvest in 8–10 weeks. However, some varieties can take up to 12 weeks to fully mature. Strains such as Bubble Kush Automatic and Quick One fall towards the faster end of the spectrum, whereas varieties like Royal Creamatic and Royal Haze Automatic take a few more weeks to ready their buds for harvest.
It’s important to keep the towels moist because the seeds can rot if there’s too much water. Similarly, the seeds won’t sprout if the towels are completely dry. Don’t make the mistake of directly planting the seeds, especially if you’re doing it for the first time. Once the seeds show a tap root, plant the seeds in the final container.
In general, autoflowers stay for 4 weeks in the vegetative stage, so about 4 weeks. Then your auto will start developing flowers for 3 weeks, and fattening up the buds for the last 3 weeks.
Despite having to keep the seeds in damp paper towels, make sure they are not completely wet, too much water can rot the seeds. The best way to identify this is by smell if the paper towels start to smell like mold, immediately take them out and change the towels.
If you’re new to autoflower growing and are looking for an autoflower grow guide or want to know how to grow autoflowering strains, here are a couple of tips to have you growing in no time.
Some growers use small plastic cups to plant seeds. While this method may work with photoperiod plants, it’s not recommended for autoflowers. If you’re already committed the mistake of planting them in small containers, try to transplant the plant only when the soil is moist. If the soil is too wet, the roots tend to break, and if it’s too dry, transplanting becomes a pain. Of course, experienced growers do transplant autoflowers but it’s not really necessary.
If everything went well your plant should be ready to enter the pre-flowering stage. Some plants will start showing pistils at this point but others will just show signs that they’re about to enter pre-flower, such as the flowering sites turning light-green. The pre-flowering stage happens any time from week 4 to 5. Some may not, but they are super close.
By traditional cannabis plants, we are referring to photoperiod plants. Let’s imagine you plant a regular cannabis seed today. You wait for it to complete its vegetative stage while providing anywhere from 16-18 hours of light. If they are growing outside, it’s out of your control and you can only plant them based on the seasons. Anyway, coming back to the vegetative stage, the plant will grow indefinitely in the vegetative or growth stage until it receives almost 16-18 hours of light. Once the number of hours reduces and it begins to receive only 12-14 hours, the flowering stage is triggered.
Just like in the other growth stages, you should adjust the conditions; During the first half of the flowering stage the humidity and temperature should be the following:
Week 6: First Half of Flowering
Remember that cannabis plants depend on the environment to thrive so make sure the conditions are within the acceptable range. During the vegetative stage you should keep the following conditions for the best plant growth possible:
Just in case you’re clueless about autoflowers, let’s start with:
Seedlings are extremely fragile so make sure the conditions are on point and that you handle them with care!
Considering that you’ve germinated the seeds successfully, you can plant the seeds in their respective containers. Autos can be transplanted, yes, but leave that to the experts. They will do far better if you do NOT transplant them and instead plant them directly in the containers you’ve chosen.
