how to grow autoflowering weed indoors

For germinating your autoflowering cannabis seeds, we recommend using the Autoflowering Starter Kit for best results.

Essentially, this entails having multiple plants in different stages of growth at any given time. In this way, you can time things just right so that there is always weed ready to bloom and harvest. This gives you the potential for a never-ending supply that doesn’t require excess effort from you!

TIP 4: GROW IN LIGHT AND AIRY SOIL

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.

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.

Many cannabis growers overfeed their cannabis plants. This isn’t too surprising, seeing that makers of cannabis nutrients want us to believe our plants require constant supplementation to survive and thrive. Nothing could be further from the truth.

What soil should I use for autoflowering seeds?

Grow with the Sun

You’ve reached the best part of this autoflower grow guide – the end. Depending on your specific strain, you may be ready for harvest anywhere from 10-12 weeks. You’ll know it’s time when most of the trichomes are whitish, and the pistils are brownish-red.

Week 10-12: Harvest time!

Our complete grow kits include everything you need to go from seed to your very own supply of high grade medical cannabis.

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 .

If growing male and female cannabis seeds, they’ll start to show their sex organs, or “pre-flowers,” after 8-10 weeks from germination.

The main drawback to growing from seed is there is no guarantee as to what you’ll end up with—if you buy a regular pack of cannabis seeds, it will be a mix of males and females. You’ll need to sex them out (more below) to identify the males and get rid of them, because you don’t want your females producing seeds.

Transplanting germinated cannabis seeds

Keep a close eye on the temperature and moisture level of the soil to keep the seed happy. It’s very delicate at this stage. Use a spray bottle to water it—over-watering can suffocate and kill the delicate sprout.

Germination is the process in which a seed sprouts and begins to grow into a new plant. Also referred to as “popping,” germination is the very first step in starting your weed grow.

These are referred to as “bagseeds” and whether or not you can grow one will depend on where it came from.

Autoflowering strains require some preparation, as they will grow quickly and start to flower whether or not you’re ready for them.
