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.
When starting your seeds, and for young plants, you can also use standard fluorescent lamps such as T5 lights. These use very little energy and don’t get warm, so there is no risk of burning your sensitive seedlings.
TIP 11: ENSURE GOOD AIRFLOW, HUMIDITY, AND TEMPERATURE

After your cannabis plants have sprouted, don’t feed them for at least two weeks. Even then, you may only want to give nutrients if a plant shows signs of a deficit, like yellow leaves. Autoflowers grown in standard potting mixes should do well all the way to flowering with no additional nutrients. From here, you can start to administer bloom-specific solutions.
Autoflowering cannabis tends to be at its healthiest when given just the right amount of nutrients. In some cases, plants can go through the entire seedling and veg phases without any supplemental nutes, as most soil mixes already contain enough macronutrients and micronutrients to support these phases of growth.
60–65 days from planting your seeds. Since many autoflowers won’t get taller than 50–70cm, they are ideal for growing indoors, where space is often limited.
Nutrients play a big role in growing autoflowering cannabis strains. Autoflowers are compact, so they don’t need loads of nutes in order to survive. In fact, autoflowers grow best when light fertilizers are used. It’s also important to feed the right nutrients at the right time.
After all, a plant that gives you lip-smacking buds in just 2 months deserves some research, eh? Autoflowers may scare you at first, but if you avoid a few common mistakes, you’ll harvest much more than you can imagine, and it only gets better.
6. Do not transplant
The appropriate pot size can also help you control the height of your cannabis plants, usually, a 12L pot will allow your plant to develop to its maximum, an auto in a 7L pot will grow up to 70cm and in a 3L pot will grow around 40cm.
Autoflower cannabis has always sparked debates among growers in the cannabis community. Due to a dearth of knowledge or experience, many growers avoid growing autoflowers. Beginners are expected to only grow photoperiod plants, and while the fear of something new and unexpected is understandable, you might discover something more amazing if you just try.
Sometimes, it just so happens that the plant refuses to respond even if you’ve done everything. In such cases, flush the plants with lots of water (at least double or triple the size of the container) to reduce any nutrient or salt buildup so that the plants can breathe again. Flushing is typically done at the end, but it doesn’t hurt the plant even if you do it in between because it reduces buildups to a good extent.
However, their yields aren’t as spectacular as those obtained from photoperiod giants, but, the trade-off for brevity makes the decision worthwhile for most growers.

LIGHT SCHEDULE FOR AUTOFLOWERING STRAINS
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.
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.
The pH value of your soil will determine how well your plants can access the nutrients within. If the pH becomes too high (alkaline) or too low (acidic), nutrient lockout will occur and deficiencies will set in. Cannabis plants thrive in a soil pH of between 6.0 and 6.5. Use a pH tester to track pH throughout your grow.
