Growing Marijuana From Seed
Cannabis seeds require three things to germinate: water, heat, and air. Because of this, there are many methods to germinate your seeds. The most common and simplest method involves the use of paper towels saturated in water.
For this method you will need:
- Two clean plates
- Paper towels
Step 1: Take four sheets of paper towels and soak them with distilled water. The sheets should be soaked but shouldn’t have excess water running off.
Step 2: Take two of the paper towels and place them on a plate. Then, place the cannabis seeds at least an inch apart from each other and cover them with the remaining two sheets of water-soaked paper towels.
Step 3: To create a dark protected space, take another plate and flip it over to cover the seeds (like a dome).
Step 4: Make sure the area they’re kept in is warm, somewhere between 70-90°F.
After these steps have been completed, it’s time to wait. You can check the paper towels to make sure they’re still saturated, and if they seem to be losing their moisture, you can apply more water to keep the seeds happy.
Some seeds germinate very rapidly while others can take several days. You know a seed has germinated once the seed splits and a single sprout appears.
This is the tap root, which will become the main stem of the plant, and seeing it is a sign of a successful germination. It’s important to keep this area sterile, so don’t touch the seeds or the tap root as they begin to split.
Once you see the tap root, it’s time to transfer your germinated seed into its growing medium. Small 2-inch pots are a good place to start. Fill the pots with loose, airy potting soil and poke a hole in the middle about a quarter-inch down using a pen or pencil.
To transfer the seed, use a pair of tweezers to gently pick it up, then drop the seed in the hole with the tap root facing down and lightly cover it with soil.
Next, you’ll need to water the soil. Initially, use a spray bottle to provide moisture without over-saturating the soil. You want to give the seed water, but over-watering can suffocate and kill the delicate sprout.
Pay attention to the temperature and the moisture level of the soil to keep the seed happy, and within a week or so you should see a seedling begin to grow from the soil.
Types of marijuana seeds
There are few aspects of marijuana plants that are more important than the seeds. Everything begins with the seed, so you’d better make the seed count. In other words, you should carefully decide what type of seed you would like to buy. Let’s look at some of the options.
Regular marijuana seeds
Regular seeds are, just as they sound, the normal type of marijuana seed that most people have traditionally grown with. These seeds will come with approximately 50% male and 50% female, so you will have to diligent about removing the males if you are growing with regular seed.
Feminized marijuana seeds
These seeds are ones that will only produce female plants. These aren’t naturally occurring — they need to be created to get them to be all female (which is also a marijuana grower’s dream). Buying feminized seed is the most efficient option for most marijuana growers.
Seeds that autoflower are not photosensitive, instead they start to flower based on timing. In other words, they flower automatically. These can work really well for growing all year round, although it doesn’t make much sense for indoor growers who already can decide when they want their plants to begin flowering by manipulating the light cycle.
