how to grow autoflowering weed indoors

Cannabis plant sex organs appear on nodes, the points where branches grow off from the main stalk.

Cultivating males is important for breeders trying to cross new strains and genetics, but most people growing for buds will want to remove the males.

In commercial cannabis production, generally, growers will plant many seeds of one strain and choose the best plant. They will then take clones from that individual plant, which allows for consistent genetics for mass production.

Seeds for these varieties are now widely available online and through dispensaries. It should be noted, however, that any plant grown from these seeds is not guaranteed to produce high levels of CBD, as it takes many years to create a seed line that produces consistent results. A grower looking to produce cannabis with a certain THC to CBD ratio will need to grow from a tested and proven clone or seed.

Growing marijuana takes a certain level of commitment: time, energy, and financial resources, so be sure you can commit to the whole process.

If you don’t like the flavor, effects, or even the look of the bud, then it’s probably not worth growing.

Most cannabis plants begin flowering when the amount of light they receive on a daily basis reduces. Outdoors, this happens when the sun starts setting earlier in the day as the season turns from summer to autumn. Indoor growers can control when a plant flowers by reducing the daily amount of light plants receive from 18 hours to 12 hours.

If you are growing autoflowers indoors , this is also the time for starting low-stress training, if you’re into that sort of thing. Training is helpful; however, it can also be risky and should only be done during the early part of the vegetative stage. Training helps forming buds receive the most energy from their light source – and that is definitely a good thing.

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 .

At this point, your seedling has begun creating energy from its light source. If you are growing indoors, you’ll want to use LED lights to give your autoflowering plant some light. Choose LEDs – they save energy and direct less heat. Plus, they are affordable. You’ll only need a single light to grow a large plant in an indoor autoflower grow setup .

Week 3-4: Vegetation is flourishing

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.

We’re almost done! See how easy an autoflower grow can be? In week 7, you’re going to focus on maintaining the environment. If you have your plants outside, make sure it’s not too hot or wet. If they are inside, check the humidity. You should be near 40% humidity instead of the 70% you started with during the vegetative period.

What size pots should I use for Autoflowers?

Autoflowering seeds are a great idea because they grow faster than regular seeds. They’re also preferred by many marijuana growers because they are easy to grow.

More often than not, weed cultivators don’t just want to harvest once or twice per year. Wouldn’t it be great if you always had some plants ready to harvest? With the perpetual harvest method, you can do exactly that!

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.

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.

TIP 14: HARVEST ALL YEAR ROUND

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.

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.

With conventional cannabis, this would involve at least two separate growing areas. Luckily, with autoflowers, you can squeeze plants in different stages of growth all into the same room. As autoflowers take about 8–10 weeks from seed to harvest, all you need to do to enjoy a constant stash is offset planting by 2–4 weeks. This way, when you harvest one plant, the next is already starting to flower, waiting patiently in line.

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.
