auto flower grow

Can you grow autoflowering cannabis in a greenhouse?

Talking about nutrients, some growers try to make their own nutes. While it’s completely okay to do so, you should avoid doing it if you’ve never done that before. Nutrients are expensive and it’s tempting to make your own, but try to attempt that after you’ve gained some experience.

After all, a plant that gives you lip-smacking buds in just 2 months deserves some research, eh? Autoflowers may scare you at first, but if you avoid a few common mistakes, you’ll harvest much more than you can imagine, and it only gets better.

10. Frequently Asked Questions About Autoflowers

Yes, you can, although it’s not recommended if you want to get the best results possible but if this is the only way you have, make sure your plant gets at least 4-6 hours of direct sunlight a day and that you’re using at least a 10-liter pot.

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.

But when compared to a photoperiod plant, an autoflower has a limited lifespan so things such as stress, damage, or a bad environment can ultimately affect your auto’s height, so it’s ideal to provide optimum grow conditions to get the best results possible.

And this is true for all plants. Can you expect to grow tomatoes if you’re clueless about using nutrients? Or, can you harvest cucumbers if you don’t even know when to harvest them? No? Similarly, autoflowers need you to follow a few basic guidelines like other plants, and you’ll do just fine if you take the time to understand them.

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.

Their impressive resistance to pathogens and pests allows them to withstand the challenges of outdoor growing.

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 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.

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.

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.

If you have low temperatures during early growth of an auto you may permanently reduce the ability of your auto to reach it’s full potential. Likewise, if you have serious nutrient issues, overwatering, poor lighting etc you will also likely see permanently stunted growth on your autoflower plants.

Because many indoor autoflowers are cultivated under 20 hours of daily light, they prefer slightly lower light intensity than a photoperiod in bloom. The logic is simple to grasp. Any light will produce a set amount of light, measured in micro moles (μmol) per square metre per second. When that light is on for 20 hours per day (autoflower seeds), it produces a greater the number of daily micro moles then when it is on for just 12 hours per day (photoperiod feminised cannabis seeds). Therefore, in order to retain the same amount of daily light (DLI, or Daily Light Integral) autoflowers can give better results with a slightly lower powered light compared to the light requirements of a photoperiod strain in bloom.

How to kickstart your autoflower growth properly?

Indoor, or outdoor, cannabis plants will struggle to reach their full potential without access to intense light with the right spectrum. If you don’t have sufficient light it will definitely compromise the final autoflower height.

Because the average autoflower height tends to be somewhat shorter than photoperiod strains, many growers find that they can manage with slightly smaller grow tents. This means that the recommended grow tent height for autoflowers can be shorter. You may be able to grow your autoflower seeds in tents which are perhaps just 1.5m tall.

The harvest quality and quantity are determined by several factors. Your autoflower seeds need the best possible start in life, that means good germination and care in the first few weeks. At all costs, avoid over watering and overfeeding your delicate young plants since this may permanently restrict their potential. Trying to grow in waterlogged soil is one of the most frequent reasons that growers end up with small autos.
