starting autoflower seeds

It’s important to keep the delicate seed sterile, so don’t touch the seed or taproot as it begins to split.

The main drawback to growing from seed is there is no guarantee as to what you’ll end up with—if you buy a regular pack of cannabis seeds, it will be a mix of males and females. You’ll need to sex them out (more below) to identify the males and get rid of them, because you don’t want your females producing seeds.

These are referred to as “bagseeds” and whether or not you can grow one will depend on where it came from.

Step 2

Cultivating males is important for breeders trying to cross new strains and genetics, but most people growing for buds will want to remove the males.

After completing these steps, it’s time to wait. Check the paper towels once a day to make sure they’re still saturated, and if they are losing moisture, apply more water to keep the seeds happy.

Even if your seed sprouts fast and grows vigorously, it still has roughly a 50/50 chance of being female and producing buds, instead of turning out to be a male.

Females will have a round structure with long hairs—these hairs will develop into pistils, which will catch pollen in the air.

You will need to invest in a few pieces of unique equipment, but by using stone wool blocks, you can create a perfect utopia for germinating cannabis seeds. Soak the stone wool blocks in the same way you would a soil medium. The wool will retain the moisture and prevent the need to water during the early stages of germination. After the wool blocks are soaked, stick them in a plastic tray that also has a lid. Large cake tubs are ideal.

There is, of course, a far simpler way to germinate seeds. Ideal for beginners, the feminized starter kit by Royal Queen Seeds has everything you need to kick-start your next cannabis project.

USING STONE WOOL BLOCKS

Often overlooked, it is all too easy to assume that the vegetative and flowering stages of cannabis growth are the most critical parts of the plant’s life cycle. However, with the chance of failure high unless you know what you’re doing, poor planning when it comes to germination can make or break your next grow. Giving your cannabis seeds the best possible start on their journey to bulging buds is a surefire way to encourage a healthy and robust plant.

Your growing pots will need to be placed in a damp climate that is within the temperature range listed under our golden rules. After 4–10 days, you should see a young seedling sprout, while the roots will have begun to develop underneath the soil. The entire plant and its soil can now be transferred to a larger pot, where normal growing routines should start.

Two or three weeks after germination, your young seedlings should be ready for their new home. At this point you have two options; transplanting them into soil pots, or taking on the challenge of hydroponics. You’ll know when the seedlings are ready to be moved because the root system should start to poke out of the bottom of the wool blocks. As long as the roots haven’t begun to engulf the bottom half of the wool block, they will seek out water and nutrients in their new surroundings and continue to grow downwards.

Maintaining the ideal temperature (between 22–25°C/71–77°F) and moisture for germination is tricky. Leaving seeds out in the open environment or on a windowsill is far from ideal; a DIY climate-controlled cupboard would do a much better service. A warming mat is perfect for maintaining a constant temperature, but it doesn’t tackle the issue of moisture.

The chamber can be used with any type of medium, Rockwool cubes, peat pellets, coco fiber, perlite, or even soil and they keep the best environment for sprouting seeds and the first days of the seedling.

So when germinating autoflowers you should keep the temperature between 21-26°C and the humidity as close as 90% as you can.

Scarification is a method used to make ridges on the seed to help water pass through, to do this properly, you will need a piece of sandpaper but you can improvise and do it with a matchbox.

Step 3

If you are storing seeds for your next grow cycle, you need to keep them in ideal conditions.

Sprinkle a little bit of water if needed, you’ll know they’re ready to be transplanted when the radicle is around 1-3cm long.

First of all, we need to understand the anatomy of a cannabis seed.

As the title says, grab a glass cup and fill it half with water.
