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.
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.
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.
TIP 11: ENSURE GOOD AIRFLOW, HUMIDITY, AND TEMPERATURE
As previously mentioned, autoflowers are less forgiving when it comes to major or sustained errors, which means you must water your autoflowering girls properly.
The best solution is to make your own soil mix at home.
As for the right type of light, LEDs are now replacing HPS lighting in grow rooms and tents everywhere. They may be more expensive outright, but they use a lot less energy than HPS, so you will save massively on energy costs over time. If you’re using an LED grow light, you may want to see whether it is also equipped with UV lights. Some growers say that UV light makes for better taste and potency.
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.
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.
LIGHT SCHEDULE FOR AUTOFLOWERING STRAINS
8 weeks, with subsequent weekly harvests when growing fast strains.
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.
Autoflowering cannabis plants are hardy, fast, and easy to cultivate in confined spaces. What’s not to love? Learn how to grow them week by week below.
To set things straight, let’s begin by saying that autoflowers are really easy to grow. In fact, beginners can try growing autoflowers with little to no experience as long as they understand the basics 1 .
For example, cannabis needs more nitrogen in the vegetative stage. In the pre-flowering stage, nutrients with more phosphorous are preferred, and in the flowering stage needs a lot more potassium than nitrogen or phosphorous.
1. Knowing the basics
A dry pot will be easy to lift whereas container with lots of water will be heavy. The trick is to not let the soil go too dry or too wet, so water the plants only when the pot isn’t too heavy or light.
This solely depends on your climate, you need to remember that autos prefer dry sunny days so if you’re planning to have just one grow cycle, you can start them 1-2 weeks into Summer, and if you’re planning to have 2 harvests, start the next one right after finishing the first one.
Of course you can, you can grow autoflowers in a greenhouse all year round as long as you keep the inside temperature to a minimum of 15°C and there’s enough ventilation, airflow, and sunlight.
