Germination is the first stage of the cannabis growth cycle : the process that brings a cannabis seed out of its hibernation period and starts the cannabis growth process. After all, seeds in a bag don’t spontaneously start developing roots. Also known as “popping” seeds, seed germination begins when a seed receives environmental cues letting it know the setting is perfect to start growth.
The environment in which seeds germinate also plays a role in the outcome. While there are several different germination methods, each requires proper moisture, minimal handling, and warm springtime temperatures between 68-72 degrees Fahrenheit.
What is germination?
It’s essential to acquire high-quality cannabis seeds for germination, as these will go on to become high-quality cannabis plants. Seeds that are fresh-feeling or too green indicate that they haven’t reached full maturity, while pale-green, white, or very dark cannabis seeds may have trouble sprouting. However, it’s tricky to know the outcome of a popped seed, so trying may be worthwhile. If you’re not ready to pop your seeds yet, store them in a dark, cool place until it’s time for germination.
When a seed enters an environment with enough moisture, it will increase in size and slowly break out of its shell. A seedling or germ forms from which roots will emerge, helping the baby plant absorb nutrients from the soil. Seeds naturally develop roots facing down and stems stretching upward, allowing the young cannabis plant to simultaneously feed off light and earth.
To employ water germination, fill a glass with tap water and let it sit until it reaches room temperature or around 65 degrees Fahrenheit. Add two to three plant seeds per cup and allow them to sit, watching for any changes. Change the water to fresh tap water every two days, making sure it stays at room temperature.
If you’re one of those people that have to have control over everything you might find yourself wondering how long cannabis seeds germinate. The long and short of it is that it usually takes 24 to 48 hours for the cannabis seeds to germinate. If they are placed somewhere moist, warm and dark, like a cupboard or in a propagator. These are ideal places for the Cannabis seeds to germinate and they will crack out of their protective shells.
After another two days, they should have a pair of leaves then continue growing for another two weeks until they begin the vegetation period. If you are concerned that the seed cover is still on the leaf or concerned about how long the cannabis seed germination will still take, just remember the more warmth and moisture (not dampness) will accelerate the process for the Cannabis seeds to germinate and within 24 to 48 hours it should be completely out of its shell.
So now you know how long cannabis seeds germinate, what will happen after?

There is the risk here of damaging the roots during transfer, the risk of the seeds getting too much light, and of course, the risk of drowning. Some people do prefer this method, but we find it to be way too risky when compared to the others.
You don’t want to use overly porous materials here because once the roots start to come out of the seed, you run the risk of having them grow into the porous paper towel. The result here will be that the roots are hard to remove from the paper towel, potentially damaging them before you get the chance to transfer them into good potting soil.
Once again, use a plant sprayer or just drip some water onto the paper towels to moisten them. Be sure to get them wet enough so that the seeds inside get moisture, but don’t soak it to the point of dripping because you will drown the seeds.

Now that you know how long it takes for a marijuana seed to germinate, you probably want to know how to germinate them in the first place. Well, there are several common methods used for weed seed germination.
It does kind of come down to chance, seed health, and the conditions. Trial and error and repeated tries are things you will have to deal with if you are going to attempt marijuana seed germination.
Let’s quickly go over each of them, how well they work, and what you need to do in order to achieve success with each germination method.
Simply take the peat pellet, soak it in warm water for a couple of minutes, plant the seed about 1.5 cm deep in it, and then place the peat pellet in a fairly dark area with the proper temperature level.
