If you used any nutrients, you’d want to start the process of flushing on week 8. This means you stop giving your plants anything other than water. You don’t want any of that stuff in your final harvest. Flood the plant’s soil so that any excess chemicals are cleared before the plant can eat any more of them. This will prevent those chemicals from remaining in the plant when it’s time to harvest. Repeat the flooding process multiple times for up to two weeks, but don’t overdo it. Allow your pot to dry out between flushings.
Whether you’re new to growing cannabis or you’ve been growing pot for years, autoflowering strains are possibly the best way to go. You could be growing autoflowers indoors in soil , or setting up a hydroponic autoflower grow , it doesn’t matter. Autoflowering seeds are ready for harvest in just eight weeks, while still producing potent effects.
Finally, it’s time to do a little trimming. Find some trimmers and remove the small fan leaves from the bottom nodes. You can also cut off any of the fan leaves near the top that don’t look that great. This process will help your plant get more light and reduce the chance of mold developing.
Week 5-6: Flowering
Grow with the Sun
Especially when growing autoflowers indoors , your results can vary depending on the strain and the quality of the seeds. If your plant seems to progress slower or faster than others, don’t let it bother you. Come harvest time, you may find that you were worrying about nothing.
The fact that autoflowers can grow so fast means they spend less time fighting off pests and viruses. On top of that, many autoflowering strains are bred with strong genetics to fight off these risks. The end results are plants that are incredibly easy to grow, even if you plan on growing autoflowers outdoors .
Continue following the lighting, temperature, humidity, and watering guidelines that you’ve been following since the beginning of week 7. If you flushed your plants, the fan leaves might look rust-colored or otherwise discolored, this is perfectly normal.
After you’ve planted the seed, the care begins. Make sure you have enough water at all times, but do not let your plant drown. If desired, add some nutrition at the start of flowering and cultivate your plant completely. After about 10 to 12 weeks your plant will be ready to be harvested.
When it comes to the lights there is plenty of choice. Basically it’s hard to make a wrong decision as each choice is a good one. LED, CFL, HPS or MH lamps, the choice is yours!
Growing with LED lighting is gaining popularity lately as LED lamps are more economical, emit less heat and can be placed closer to the plant which saves space.
In this article we explain step-by-step how to grow autoflowers indoors and outdoors, what you need, which varieties are available for beginners and how long they should be grown. Depending on your situation and preferences, you decide whether you want to grow the autoflower indoors or outdoors.
Growing autoflowers outdoors
Yes, you can very well grow an autoflower indoors without lights. These plants love to stand on the windowsill in front of the window or in the conservatory. In any case, choose a sunny spot. A window sill or conservatory facing south is preferable. This way you ensure the plant of maximum sunlight.
Above you can read that indoor growing offers many advantages. But can you grow autoflowers outdoors as well? Sure you can! Let’s look at the advantages first.
Many growers choose to grow their autoflower indoors which is not strange when you look at the advantages.
“Flushing” is when you stop feeding nutrients, and only administer pH-adjusted water in the last 1–2 weeks before harvest. This gets rid of the remaining mineral salts that have accumulated. Without any nutrients remaining in the soil, the plant will draw stored nutrients from its foliage; this is why cannabis in late flowering turns yellow. The goal of flushing is to make for purer and better-tasting buds, as you don’t want to smoke whatever chemicals you’ve fed your plants. So flush them out before you harvest.
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!
Recipe for DIY light and airy soil for autoflowers:
TIP 13: HARVEST GRADUALLY
Make sure to provide your autoflowering ladies with good airflow. A gentle breeze of fresh air from a ventilator ensures humidity levels in your grow room stay low, which helps prevent the growth of mould. If your plants have dried leaves, which is not uncommon in the later stage of flowering, remove them for some better airflow around the buds.
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.
The other thing you should consider when selecting a strain is its growing characteristics. Some strains may be easier than others to manage, or are known to grow and flower exceptionally fast. If you’re still new to growing, or simply want to grow great bud in a very short time, you may want to take a look at our Easy Bud or Quick One.
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.
