After you’ve prepared the mix, add some Easy Boost Organic Nutrition to the blend. These pellets will slowly release adequate levels of nutrition into the soil, providing foundational elements and minerals for the entire growing cycle. Add some mycorrhiza to the soil to help your plants flourish later down the line. These symbiotic fungi will bind to the root system and help your plants uptake nutrients more effectively.
Next, poke a 10–15mm hole into a pot with your soil mix. Sow your seed directly into its final pot to avoid the stress of repotting later down the line. Transplanting causes plants to go into shock, and autoflowers grow so fast that they’ll struggle to recover. Place a seed in the hole and cover lightly with soil. You’ll see your seedling emerge in the next few days.
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 GROW GUIDE: HOW TO GROW AUTOFLOWERS WEEK BY WEEK
8 weeks, with subsequent weekly harvests when growing fast strains.
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.
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.
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.
During the earliest stages of growth, the seedling will only grow as tall as one inch, producing its first set of leaves. By this time, the tap root of the seedling will grow downwards anchoring itself to the base of the pot. If grown in soil, seedlings can be fed plain water or a mild nutrient solution root booster.
By day 42, the plants will begin to fill out and take on a stacked and chunky appearance. The internodal spacing will become filled with flower sites, and the height of the plants will begin to slow down, as all energy is spent on flower production. The resin will begin to form very quickly covering the buds, with the aroma and terpenes making themselves well known. Plant height will range between 70-125cm
Once you have hit the 10-week mark, your autoflowering plants will be fully mature and ready to harvest. The buds will be as thick as golf balls and should have filled every branch and internodal spacing. The terpenes will be the most aromatic, they can be, with the buds encrusted with trichomes, including the surrounding leaves. At this point, you are ready to get your trimming scissors out and begin harvesting the plants.
Now you are halfway through your growth cycle and will notice the growth structure and appearance of the plant will be growing tall, bushy, and with high resistance to strong winds.
Autoflowering cultivars changed the way that Cannabis could be grown indoors or outdoors, without being dependent on specific light cycles. From seed until the point of harvest, autos will begin to flower despite the various seasons during the year, making these low maintenance and highly resistant plants a grower’s best friend. So, if you’re wondering how long does it take for weed plants to grow ? In this article we explain what to consider when growing autos, the benefits associated, the life cycle broken down week by week including our grow tips.
