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.
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.
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.
A NOTE ON PH
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 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.
You can make your own potting mix using the following formula:
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
“Flushing” is when you stop feeding nutrients, and only administer pH-adjusted water in the last 1–2 weeks before harvest. This gets rid of the remaining mineral salts that have accumulated. Without any nutrients remaining in the soil, the plant will draw stored nutrients from its foliage; this is why cannabis in late flowering turns yellow. The goal of flushing is to make for purer and better-tasting buds, as you don’t want to smoke whatever chemicals you’ve fed your plants. So flush them out before you harvest.
You can also grow your cannabis in organic soil. This will ensure your plants have everything they need for healthy growth all the way to harvest, and you won’t ever need to administer additional nutrients! Some growers make their own organic super soils, which are perfect for growing autoflowers. That being said, it’s important the soil is not too “hot” given the sensitivity of these cultivars.
Autoflowers are a class of cannabis that has only thrived on the commercial market in the last few years. Today, they are taking the market by storm with their ease of growth and great results. With these tips for growing autoflowers indoors, you can make the most of your autoflowering grow-op!
TIP 13: HARVEST GRADUALLY
Recipe for DIY light and airy soil for autoflowers:
For germinating your autoflowering cannabis seeds, we recommend using the Autoflowering Starter Kit for best results.
You don’t need to harvest your entire plant all at once! Chances are, the top buds may be done earlier than some of the lower buds further away from your lights. These buds may need a little more time to ripen. So instead of taking your clippers and collecting them all, take only the topmost buds and allow the others a few days more to finish.
As previously mentioned, autoflowers are less forgiving when it comes to major or sustained errors, which means you must water your autoflowering girls properly.
As a grower, your job is to ensure that all the buds receive equal light, and that’s where LST helps a great deal. Most growers begin LST after the plants are “Topped”. Topping is another technique that involves cutting off the tip of the main stem, forcing the plant to grow more colas rather than one. Beginners can even “FIM” their plants, which is another method where you cut off only a part of the tip instead of cutting it entirely.
In particular, full-spectrum LEDs work the best for any type of autoflower. The higher the lumens, the better the yields, but if you cannot afford expensive lighting equipment, CFLs will work well during the vegetative phase.
Cannabis growers are always on the hunt to understand the tips and tricks to maximize yields in autoflowers. Most growers have the talent, but they lack information. And that’s a serious handicap when growing autoflowers. Autoflowers grow fast and produce yields in a short span of time, but that comes only with experience. You could grow them just like photoperiod plants, but there are several stark differences.
It’s also critical to transplant only after the roots have filled out in the container since the soil will drop off in clumps with the roots stuck to them. In other words, wait until the plant is a little root bound. Since there are so many conditions, it’s best to start directly in the final containers. With no disturbance, you’re all set to get great yields.
Sure, some growers grow autos just like photoperiod plants by transplanting them not once by twice! However, they are experienced growers that have attained success after several failures.
LST is a method that requires bending the stems of the plant so that the light penetrates to the lower parts of the plant. Generally, autoflowers tend to grow one main massive cola while the rest of the plant produces small budlets known as popcorn buds.
The pH is an important factor in determining the yields of autoflowering cannabis strains. Whether you grow hydroponically or use soil as a medium, pH is critical. Although many growers assume that the plant is suffering from nutrient deficiencies, most issues crop up only due to pH imbalance.
