Harvest up to a pound
We’re almost done! See how easy an autoflower grow can be? In week 7, you’re going to focus on maintaining the environment. If you have your plants outside, make sure it’s not too hot or wet. If they are inside, check the humidity. You should be near 40% humidity instead of the 70% you started with during the vegetative period.
How to Grow Autoflower Plants
This characteristic makes growing autoflowers outdoors perfect when you want to take advantage of mother nature’s natural light source. Whereas most plants can only grow during a specific season, autoflowers can successfully pull off two to three seasons instead of one. As long as you germinate your seeds by the beginning of spring, protect your plants from extreme temperatures (the 90s and above), and the humidity stays between 70 and 90%, you can enjoy a very long outdoor growing season.
How do you maximize autoflower yield?
Especially when growing autoflowers indoors , your results can vary depending on the strain and the quality of the seeds. If your plant seems to progress slower or faster than others, don’t let it bother you. Come harvest time, you may find that you were worrying about nothing.
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.
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.
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.
A NOTE ON PH
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.

Germination usually takes 1–3 days. During this time, your seeds will activate and send a root down into the soil and a shoot above the surface. To begin the germination process, you’ll need to prepare a suitable soil mix. Autoflowers don’t need as much nutrients as photoperiod varieties and prefer light and airy soil.
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.
Here’s a great LST example by Santacabrera showing how to gently bend the middle colas of an auto-flowering plant down and away from the center without cutting or harming the plant.
The term “12-12” stands for 12 hours of light and 12 hours of dark each day, and it “tells” photoperiod plants to enter the flowering stage and make buds. During their daily dark period, photoperiod plants need to receive complete darkness without interruption. This light schedule initiates flowering, and must be maintained throughout the entire flowering stage until harvest.
Light Schedule is 20 on and 4 off (20-4). Used that light schedule for the whole grow. This is my first time growing. The plant ended up being just under 2 feet tall at harvest. Harvested on day 67 from seed.

Because of this, auto-flowering clones live short lives and most growers strongly recommend against cloning auto strains because they stay extremely small and will not live long enough to produce good yields.
These are my 4 x Fastbud #2´s (this strain has now been bred into Ice Cool Auto, which may be even better). I chopped 2 a couple of nights ago and the others today. Day 65 from seed under a mixture of 400 & 600W HPS.
