how to plant autoflower weed seeds

Learn to grow autoflowering cannabis.

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.

HOW LONG DO AUTOFLOWERS TAKE FROM SEED TO HARVEST?

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.

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.

For germinating your autoflowering cannabis seeds, we recommend using the Autoflowering Starter Kit for best results.

TIP 4: GROW IN LIGHT AND AIRY SOIL

Autoflowers don’t have all the time in the world to grow. Right after sprouting, your plant will need to spend a good amount of time establishing a healthy root system. When you administer a root stimulant immediately after placing your seed in the pot, this will support your plant in this crucial process. But don’t go overboard as your seedling will be very sensitive to overfeeding. Use only the minimum recommended dose of root stimulant.

Don’t top, prune, or pinch your autoflowers like you might do when growing conventional cannabis. With autoflowers, the only training method you should use is low-stress training (LST), where you carefully bend and tie down your plants so all bud sites are equally exposed to light. When performing LST on autoflowers, just stick with bending and skip the part where you’d top your plants. If you plan to do LST with your autoflowers as an alternative to a SOG, ensure that you start soon, but be gentle to avoid breaking your plants.

Note: Depending on where you live, there may be legal limits on how many plants you can grow for personal use, so make sure you know how many plants you can have.

Cannabis can be either male or female—also called “dioecious”—but only females produce the buds we all know and love. For reproduction, males have pollen sacs and pollinate females, causing female flowers to produce seeds.

A lot of classic weed strains that have been around for a while come in feminized form. Some popular fem seeds are:

Pros and cons of using cannabis seeds

Keep a close eye on the temperature and moisture level of the soil to keep the seed happy. It’s very delicate at this stage. Use a spray bottle to water it—over-watering can suffocate and kill the delicate sprout.

Sexing marijuana plants can be a time-consuming process, and if you don’t catch males, there is a risk that even one males can pollinate your entire crop, causing all of your female weed plants to produce seeds.
