Growing cannabis is an art that requires patience. Only growers that understand the science and lifecycle of the plant will succeed. The rest either fail miserably or simply give up. It’s not uncommon for beginners to fail. And since practice makes man perfect, keep at it until you finally harvest a big bunch of nugs that remind you of all the hard work.
The seedling stage is the most important stage. The plant will take a long time to recover if there’s a mishap at this stage, so be very careful. If growing indoors, hang the lights at least 17-20 inches above the seedling. Reduce the distance as the plant grows bigger. CFLs, LEDs, MH and HIDs will do as long as the seedlings are comfortable.
You can kill the plants faster by overwatering them. Not a myth; it’s a fact. So, go easy on watering. And, make sure that you supply enough water to keep the soil moist. Moist, not dripping wet or dry. As the process of photosynthesis goes on, new sets of leaves will appear.
As you enter week 6, the appearance of buds is even more apparent. A little defoliation doesn’t hurt now. Defoliation is the process of removing extra leaves to provide more light to the lower parts of the plant. Don’t overdo it, though, because the plant relies on the leaves to receive nutrients. Continue with nutrients meant for the vegetative stage as the plant will shoot up vertically.
The seedlings begin with only two true leaves. After a couple of days, a third leaf will appear. The plants don’t need any nutrients on the very first week if you’re growing in soil. For those growing in hydroponic setups, reduce the strength of the nutrients by half to allow the seedlings to adjust to them.
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.
Some growers also flush during the pre-flowering stage, when the plants are transitioning from the vegetative into the flowering stage so they can start feeding from zero, as said above, this won’t hurt your plants but should be done properly.
If you wait too much, the buds tend to produce a couch-lock effect leaning more towards the Indica side while buds harvested too early generate unpleasant psychoactive effects. Also, the main colas ripen faster than the lower portions of the plant.
Macro and micronutrients
So, if it’s your first time, stick to commercial nutrients. And, the topic on nutrients is incomplete if you don’t talk about pH. Depending on the medium 2 you choose to grow, the pH must be regulated accordingly. Cannabis plants love acidic soil, so the pH must be maintained between 5.5 to 7 in both soil and hydroponic setups.

Do autoflowers grow normal or smaller because of the Ruderalis genes?
Now that you know the basics and what to avoid, you’re all set up to start your first autoflower indoor 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.
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
8 weeks, with subsequent weekly harvests when growing fast strains.
A NOTE ON PH
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.
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.
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.
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.
