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.
Due to a shortage of time, not every training technique working for other cannabis plants suit autoflowers. For instance, HST or High-Stress-Techniques work very well on photoperiod plants, but autoflowers prefer Low-Stress-Techniques or LST.
Growers produce good yields with 24 hours, but the quality isn’t as good as plants grown in an 18/6 cycle. The light setup also plays an important role here. Although autos grow well under different types of lighting, they prefer HPS or LEDs over CFL and fluorescent lights.
If you’re adamant on transplanting, though, make sure that the medium is exactly the same. For instance, if your seedling is growing in a potting mix of coco coir and compost, it should be transplanted to another container containing the exact same mix. Water the seedling container a few hours before transplanting to ensure that the soil is moist. There’s a high risk of hurting the roots when the soil is too dry or wet.
Autoflowering cannabis is just great. Without the complications of maintaining a light cycle it can be a whole lot easier than growing standard cannabis. With seed to harvest rates as low as 9 weeks (sorry I don’t rate anything shorter) they’re fast too. But getting a successful autoflowering harvest can be tricky. Discover how to grow autos easily, and get the biggest buds, with our 10 top tips for autoflowers
A nice light mix such as 50:50 coco:perlite is best as it makes sure you get a good wet-dry cycle.
So here are our 10 top tips for autoflowers:
Continue vegetative feed until ALL upward growth stops . The auto will have started flowering before this happens (in a 9-10 week auto, you would expect to continue using veg nutes until week 6)
Great plants need a healthy root system. Even for dwarf autos you need to be using a 3 gallon pot to give the plant enough space to develop a good rootball. Using too small a container will restrict growth and limit the amount of nutrients sent upwards to be used for leaf and later bud growth.

You also need to watch the temperature in your grow room. Cannabis does best at a moderately warm room temperature of 20–25°C. Any excess heat, but also cold spells or chilly nights, can stress your plants, slow their growth, and result in poorer yields.
You don’t need to harvest your entire plant all at once! Chances are, the top buds may be done earlier than some of the lower buds further away from your lights. These buds may need a little more time to ripen. So instead of taking your clippers and collecting them all, take only the topmost buds and allow the others a few days more to finish.
With all the benefits of growing autoflowers indoors, it’s not surprising that they are immensely popular, and not just among those new to cannabis growing. Here are some vital tips on how to best grow autoflowers indoors, so you can look forward to great harvests!
TIP 12: FLUSH
Cannabis can only uptake nutrients when the soil surrounding the root zone has the right pH value. The optimal pH range here is 6.0–7.0. For growing in other media, such as coco, the pH should be lower, ranging from 5.5–6.5. If the pH of your water is not optimal (which is likely the case if you use tap water) and plants can’t uptake nutrients, this leads to sick specimens. The right pH is particularly important when growing autoflowers as they don’t have time to recover. You want to ensure your plants get all the nutrients they need during their short period of growth.
Don’t top, prune, or pinch your autoflowers like you might do when growing conventional cannabis. With autoflowers, the only training method you should use is low-stress training (LST), where you carefully bend and tie down your plants so all bud sites are equally exposed to light. When performing LST on autoflowers, just stick with bending and skip the part where you’d top your plants. If you plan to do LST with your autoflowers as an alternative to a SOG, ensure that you start soon, but be gentle to avoid breaking your plants.
You can also grow your cannabis in organic soil. This will ensure your plants have everything they need for healthy growth all the way to harvest, and you won’t ever need to administer additional nutrients! Some growers make their own organic super soils, which are perfect for growing autoflowers. That being said, it’s important the soil is not too “hot” given the sensitivity of these cultivars.
As the lifespan of autoflowering cannabis is limited, it is less forgiving when it comes to major stressors and mistakes. When plants experience high amounts of stress, growth stalls; while this may be fine for conventional cannabis that can be kept in veg longer to recover, autoflowers don’t have that luxury—they will flower regardless. As such, it’s best to start autos in their final pot right from the get-go to avoid transplant shock.
