8 weeks, with subsequent weekly harvests when growing fast strains.

Germination usually takes 1–3 days. During this time, your seeds will activate and send a root down into the soil and a shoot above the surface. To begin the germination process, you’ll need to prepare a suitable soil mix. Autoflowers don’t need as much nutrients as photoperiod varieties and prefer light and airy soil.

A NOTE ON PH

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 typically move from seed to harvest in 8–10 weeks. However, some varieties can take up to 12 weeks to fully mature. Strains such as Bubble Kush Automatic and Quick One fall towards the faster end of the spectrum, whereas varieties like Royal Creamatic and Royal Haze Automatic take a few more weeks to ready their buds for harvest.

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.

Because of this unique trait, outdoor growers can achieve multiple harvests during a single growing season. By germinating seeds week after week in early spring, you can theoretically rake in your first harvest after

Week 9: It is almost harvest time

That is the point.

As the flowering stage proceeds, you’ll want to continue lowering the humidity if you are growing indoors yet keep your plants well-watered. It is very easy to develop mold during the flowering stage, and that can ruin all of your hard work. That’s why you need to pay attention to the amount of water in the air and soil. A watering can helps you keep track of how much you are giving your plants. We include one in our Complete Kits.

Make sure you avoid three things.

To carry out a SOG with autoflowers, you’d simply plant your seeds directly into even smaller containers that allow you to fit as many plants as possible into every square metre of space. How many plants you want to use for your SOG, as well as their exact pot size, will depend on the space you have available. This may also vary from strain to strain. Feel free to experiment to find the ideal pot size and number of plants that produces the best yields in your indoor grow space.

The sea of green (SOG) method is really just a fancy term for growing a lot of smaller plants in your grow room for bigger yields. Autoflowers are ideal for growing in a SOG as they are already smaller by nature.

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.

TIP 8: CONTROL THE PH LEVEL OF YOUR WATER

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.

Recipe for DIY light and airy soil for autoflowers:

Autoflowers don’t have all the time in the world to grow. Right after sprouting, your plant will need to spend a good amount of time establishing a healthy root system. When you administer a root stimulant immediately after placing your seed in the pot, this will support your plant in this crucial process. But don’t go overboard as your seedling will be very sensitive to overfeeding. Use only the minimum recommended dose of root stimulant.

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.
