Autoflowering strains require some preparation, as they will grow quickly and start to flower whether or not you’re ready for them.
Most cannabis plants begin flowering when the amount of light they receive on a daily basis reduces. Outdoors, this happens when the sun starts setting earlier in the day as the season turns from summer to autumn. Indoor growers can control when a plant flowers by reducing the daily amount of light plants receive from 18 hours to 12 hours.
Autoflowers don’t need lots of nutrients because they’re small and don’t spend much time in the vegetative cycle. They won’t need as much veg nutrients—such as nitrogen—but will need more bloom nutrients.
Males will have round balls—these will develop into pollen sacs, which will release pollen into the air when mature.
Some seeds germinate very rapidly while others can take a while, but generally, seeds should germinate in 3-10 days. If it’s been two weeks and a seed hasn’t sprouted, it’s probably a dud and won’t sprout.
Ensure a high relative humidity of around 65–70% (use a humidity dome for germination and seedlings) and keep the soil moist, but not wet.
Don’t use dirt from your garden or any other soils of questionable quality, including old, reused soils from your previous grows. These may contain contaminants such as fungi or pests. Good-quality potting soils from trusted brands don’t come with these risks.
It does happen: Someone hands you a bag of seeds of “some great weed” for you to grow. You’re happy since you just saved some cash on seeds. The problem is, you don’t know what type of cannabis the seeds are, whether it’s sativa, indica, autoflowers, etc. We’re already off to a pretty bad start.
7. NOT MONITORING PH LEVEL
Not using proper soil is another common mistake. So, what is the “proper” soil for growing weed? Well, let’s take a look.
Seedlings are very sensitive and do not take kindly to growing mistakes like improper humidity and moisture levels. Both could spell the premature end for your seedlings.
Recommended pot sizes:
Your planting pots need to provide good drainage. Usually, there will already be holes in the bottom. If there are no holes, as can happen when you buy standard plastic pots, you will have to make them yourself. Make sure there are at least 5 openings, each about the size of a penny. As long as soil doesn’t just fall through the bottom, you’re good.
