Proper germination is pivotal to the healthy development of your autoflower marijuana plants. You can go down the traditional route of using soil, or else you can try a container with a growing medium. The paper towel method is probably the easiest way to germinate your autoflower seeds.

24-hour lighting will result in fast initial growth. However, it usually slows down after a few weeks because the plant is without adequate rest. The 18/6 schedule offers a delicate balance of plenty of light with ample rest. You also save money on your energy bill! In one month, for instance, using an 18/6 schedule against a 24/0 schedule saves you 180 hours’ worth of light!

Training Your Autoflowering Weed

As autos contain ruderalis genes, they are more robust than other marijuana plants. Remember, they are based on plants that could grow in the harsh Russian weather conditions. If there is a power outage, a typical cannabis plant will have its flowering and growth phases interrupted. This fact could play havoc with their growth cycle. You don’t have this problem with an autoflowering plant.

Since you can grow 4-5 batches a year, it adds up to a lot of bud! We also recommend preparing the next crop as you are harvesting. Pop seeds before you collect your existing plants to ensure your garden is continually producing. The fact is, you don’t need to worry about changing lighting because your plants automatically flower!

Plants with ruderalis genetics are tougher than those without but still require light to produce food for themselves. Many autoflower growers still believe that providing light 24/7 is best for their plants. This process enables them to absorb CO2 during the photosynthesis process continually. Ruderalis plants grew for a long time in the northern hemisphere. In that situation, they were exposed to 24 hours of light a day on occasion.

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.

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.

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!

TIP 9: CUT THE NUTRIENTS

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 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.

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.

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.
