Autoflowers have finally earned the respect they deserve. More importantly, they have earned a place in your grow room. With our guide to achieving maximum yields, you will crop the biggest harvest possible from your autoflowers!
TAKING AUTOFLOWERING CANNABIS YIELDS TO THE LIMIT
Autoflowers grow blazingly fast and don’t rely on light hours to enter bloom. As they make growing weed a lot more convenient, autoflowering strains have become very popular as more high-quality strains appear on the market.
There are several things growers can do to encourage bigger yields from their autoflowers.
1. START AUTOFLOWERS IN THEIR FINAL CONTAINERS
Autoflowering cannabis will race from seedling to stash in a quick 60–90 days. When autos are stressed too much or their growth is otherwise slowed, they will still bloom at the same time, and your yields will suffer.
To max out yield, you should sow seeds directly into their final containers. Alternatively, you can germinate them using the paper towel method (or whatever your preferred germination method may be) and then put them straight into large pots. A healthy root zone must be fostered early.
2. USE BIGGER POTS
The bigger the pot, the more the roots will develop and the bigger your plant will be. If you constrain it in a pot that’s too small, your plant’s development and production will be reduced. It is recommended that you use 15–20-litre pots to maximise results without overwhelming your plants. A pot that is too big will be a waste of substrate and fertiliser.
3. CONSIDER POT MATERIAL
A healthy and strong root system means healthy plants with great yields. Consider “smart pots”, like the RQS fabric pot, to give you an advantage in this domain. With their ability to prevent plants from becoming root bound, fabric pots are better for overall development.
In addition, fabric pots make it nearly impossible to overwater your cannabis as they facilitate excellent drainage.
4. USE AN AIRY GROWING MEDIUM
Autoflowers grow fast and vigorously, and have only a limited time to do so. Because of that, you want to support their growth in every way possible. A loose and airy growing medium makes it easier for your autoflowers to develop a strong root system.
If the substrate is too compact, you can make it suitable for autoflowers by adding some perlite and coco coir. See our article here for more tips on the best soil for your autoflowers.
5. ADD A ROOT STIMULANT
Another way to support root development is by adding a root stimulant. One good way to do this is by introducing beneficial fungi into your growing medium. Mycorrhizal fungi increase nutrient and water uptake, protect plants from disease, and generally encourage an optimal growing environment.

6. START SEEDLINGS INDOORS
Whether you are planning an indoor or an outdoor grow, make sure to start your seedlings indoors.
As you and your plants are on the clock from day one, you want to ensure your seedlings root well. A cool white CFL, appropriate LED, or even a sunny windowsill are adequate. Just make sure vegetative growth goes smoothly; ready or not, your autoflowers will bloom on schedule.
7. SUPPORT PLANT STRUCTURE
Staking or plant support of some kind may be needed to keep your plants upright and their buds healthy.
There are several ways you can go about this. Bamboo stakes and strings, trellis netting, or tomato plant cages can all be used to help a plant carry its heavy load. If you want more tips, see this article on five ways to support heavy buds.
8. OPT FOR 18 HOURS OF LIGHT
Opinions differ on whether keeping plants under a constant 24-hour light cycle is beneficial. 18/6 is still the most common, and will save you money on energy.
Indeed, you could potentially grow them with less light, but we are aiming for a huge harvest, so you’ll want to provide them with as many lumens as possible. More light, more buds. Easy.
When grown outdoors, your autoflowers will thrive in the fine summer weather. Sunlight for 18 hours is not essential because Mother Nature’s grow lamp is infinitely more powerful than any artificial bulb.
9. USE REVERSE OSMOSIS WATER
Your water may be fluoridated or chlorinated, or may contain other impurities that hinder healthy microbial growth in the soil. In short, if your domestic water is unsuitable for drinking, it won’t do good for your cannabis plants either. You can solve this by using reverse osmosis water.
Simply spoken, reverse osmosis is a filtration process that results in pure, ultra-filtered water. With this, you are in total control of the mineral profile of your water. This can benefit the growth of your plants and your yield.
10. DIAL IN NUTRIENTS AND PH
Autoflowers are usually smaller, so they drink and eat less compared to large photoperiod plants. If you’re using ordinary cannabis nutrients, a good idea is to start out with 50% or even 25% of the recommended dose.
Soil growers are advised to use lightly fertilised soil for autoflowering cannabis. Heavily fertilised soils will burn these babies. Aside from supplements like enzymes, vitamin B, and beneficial fungi, autoflowers don’t really require large doses of base nutrients during their short vegetative stage. Heck, with good-quality soil, your plants may do just fine without additional nutes all the way to harvest.
If you must add nutrients to the soil early on, do so sparingly. Generally, bloom nutrients and boosters are all that’s needed during their life cycle. Even in flowering, low to medium doses of nutrients will suffice. Over-fertilising plants is a common yield-thwarting mistake autoflower growers often make.
Autoflowering cannabis has come of age now both potent and productive. With our simple 10 step guide, your next autoflowering marijuana harvest will be huge.
