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.
As previously mentioned, autoflowers are less forgiving when it comes to major or sustained errors, which means you must water your autoflowering girls properly.
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.
TIP 11: ENSURE GOOD AIRFLOW, HUMIDITY, AND TEMPERATURE
When starting your seeds, and for young plants, you can also use standard fluorescent lamps such as T5 lights. These use very little energy and don’t get warm, so there is no risk of burning your sensitive seedlings.
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.
For germinating your autoflowering cannabis seeds, we recommend using the Autoflowering Starter Kit for best results.
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.
Follow the fail-safe week-by-week grow guide below for a quick and easy route to harvest time. We cover all of the parameters and variables you need to consider—at the correct times—to ensure your plants remain healthy, vigorous, and productive.
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
You can make your own potting mix using the following formula:

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.
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.
As the name suggests, autoflowering strains don’t require a change in the light cycle to enter the flowering stage. Many growers choose to keep their autoflowers on a light schedule of 18 hours on and 6 hours off during the entire growing cycle. Other cultivators choose to keep their lights on around the clock in hopes of maximising photosynthesis and growth rate, however, this can get quite expensive.
You can also minimize headaches and avoid the hassle of seed germination and sexing plants by starting with clones.
Seeds can also form in plants with genetic disorders or instability, like hermaphrodites—plants that develop both male and female reproductive parts. Generally, stress and genetic disorders are viewed as bad, so temper expectations with any plant you start from a bagseed.
What are feminized cannabis seeds?
Even if your seed sprouts fast and grows vigorously, it still has roughly a 50/50 chance of being female and producing buds, instead of turning out to be a male.
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.
