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
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.
You’ve come all this way, and the end is almost near, so don’t screw this up now! Now you’re probably asking “how to tell if my autoflower is ready for harvest?” Well, after you’ve put in all the hard work, wait for the right time. Growers use microscopes to check the trichomes that usually indicate the right time, but you can harvest when at least 50 to 70 percent of the pistils are amber in color.
It’s important to keep the towels moist because the seeds can rot if there’s too much water. Similarly, the seeds won’t sprout if the towels are completely dry. Don’t make the mistake of directly planting the seeds, especially if you’re doing it for the first time. Once the seeds show a tap root, plant the seeds in the final container.
Most autoflowers reach a height of around 50-100cm but a plant’s size depends on the genetics and growing conditions. Also, all strains are different so you will find Sativa and Indica-leaning autos; Most Indica hybrid autoflowers will stay around the 80-120cm mark but Sativa-dominant autoflowers can reach up to 175cm tall.
8. Overfeeding and underfeeding
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.
This may vary according to the genetics and growing environment, have in mind that it’s just to give you an idea of what to expect, some autoflowers may take less and others take longer.
Often referred to as popcorn buds, the lower portions stay small. However, harvesting the main colas and leaving the popcorn buds on the plant for a week more will increase yields dramatically. Be patient, and let Mother Nature do the rest for you! If you avoid these common mistakes when growing autoflowering cannabis, you’ll soon be rewarded with potent resinous buds that will last a long time if stored properly.
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 .

So, You Want to Grow an Auto-Flowering Plant!
Since photoperiod plants can be forced to remain in the vegetative stage for as long as the grower wants, a grower can take advantage of a variety of plant training methods to shape/train the plant during the vegetative stage, including LST, topping, FIMing, main-lining, ScrOG, etc.
On the flip side, if your grow doesn’t go as well as planned, at least it will be harvest time in just 2-3 months, you’ll learn a lot, and you’ll have the opportunity to try again. That being said, autos are essentially very simple and a first-time grower can easily get a great harvest on their very first grow. Plus, auto-flowering plants (and cannabis plants in general) are hardy! As long as you give them basic care, they will reward you!
Are Autos Easier to Grow?
However, when plants are fast-growing and healthy, many growers defoliate, top or FIM their plants with great results. When is it okay to top an auto?
This is my second grow but my first grow with auto flowering plants. I have the lights set on 18:6. They are in 5 gallon pots with Promix soil. I am also using technaflora nutrients.
