what if i plant 3 marijuana seeds at once

Cannabis plant sex organs appear on nodes, the points where branches grow off from the main stalk.

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.

Autoflowers can be started in early spring and will flower during the longest days of summer, taking advantage of high quality light to get bigger yields. Or, if you get a late start in the growing season, you can start autoflowers in May or June and harvest in the fall.

How to sex a pot plant

Once cannabis seeds are mature, the female plant begins to die, and seeds are either dropped to the ground where they grow into new cannabis plants next spring, or the seeds are harvested for processing into seed oil or food products, or stored so they can be sown in the ground later and become the next generation of plants.

Because they grow and flower quicker, growers can fit in multiple autoflower cannabis harvests into the span of one regular harvest.

Make sure the area the seeds are in is warm, somewhere between 70-85°F.

If you’re ready for a more serious approach, make sure you have the space for a proper garden and pop the seeds to see what fruit they bear.

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.

Fill a small seedling pot with an unfertilised or “light” potting mix. Poke a small hole about 1cm deep in the middle and place your seed inside. Cover lightly with soil. Water the soil and cover the seedling pot with clingfilm to lock in moisture. Seeds should germinate in a few days.

2. BAD GERMINATION

As an alternative to plastic pots, you can also use fabric pots (smart pots) or air pots. If you want to learn more about the different pots used to grow cannabis, check our article on the subject.

Recommended pot sizes:

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.
