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.
8 weeks, with subsequent weekly harvests when growing fast strains.
LIGHT SCHEDULE FOR AUTOFLOWERING STRAINS
The pH value of your soil will determine how well your plants can access the nutrients within. If the pH becomes too high (alkaline) or too low (acidic), nutrient lockout will occur and deficiencies will set in. Cannabis plants thrive in a soil pH of between 6.0 and 6.5. Use a pH tester to track pH throughout your grow.
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
Autoflowering strains provide fantastic results in little time, often surging from seed to harvest in as little as 8 weeks. Both beginner and advanced growers will have a fun and easy time raising these varieties.
Want to grow a big autoflower? In the open ground, roots have free rein. Logically, your autoflower can grow quite large, but when it is windy or raining your plant is less easy to protect.
Outdoors you can grow in pots or in the open ground. Both methods have advantages and disadvantages. Let us therefore first briefly explain them.
Growing autoflower indoors without lights, is that possible too?
Step 4: choose the autoflowering medium for outdoors
In this article we explain step-by-step how to grow autoflowers indoors and outdoors, what you need, which varieties are available for beginners and how long they should be grown. Depending on your situation and preferences, you decide whether you want to grow the autoflower indoors or outdoors.
For successful breeding you first choose a suitable place. Preferably in your own garden or on the balcony. In any case, make sure you have a place with sufficient sunlight.
Use a lightly fertilized, well aerated growing medium. Think of soil mix or coconut. Air pots are very suitable but also dark pots of 15 – 30 litres with drainage.
One of the most important factors for growing autoflowers outdoors is the soil. For firm buds you need a decent soil. Autoflowers like a light organic soil. Organic potting soil mixed with nutrients such as cow- and chicken manure, compost, bat guano, blood meal or permite form an ideal medium. Such a mixed soil is more than sufficient to provide the autoflower with nutrients during the whole process of growing and flowering. In case you spot a nutrient deficiency during cultivation it’s always possible to add extra nutrients.
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.
Then again, if you happen to be a medicinal cannabis user, or for some other reason choose not to get high, a low-THC, high-CBD strain like the excellent Solomatic CBD can be a good choice.

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.
As previously mentioned, autoflowers are less forgiving when it comes to major or sustained errors, which means you must water your autoflowering girls properly.
With autoflowers, you don’t need to worry about light schedules like you would with photoperiod plants. When growing autoflowers, you can just leave your lights on a 18/6 schedule (18h on, 6h off) for the entire grow, and can even grow them under 24 hours of light. Which schedule is “better” is open to debate. Many growers use the 18/6 schedule, as this gives good results while using less energy than a constant 24h cycle.
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.
