All cannabis plants, whether tall and lanky Sativa trees or compact and sturdy Indica bushes, start from a single weed seed. This tiny brown nut contains everything necessary to eventually yield hundreds or even thousands of grams of potent buds! However, to reach that point, it’s important to place the seed in a special environment that will trigger life inside it, crack the shell open, and let the roots and stalk out.

In this article, we’ll be explaining how to germinate cannabis seeds and tell you about the best ways to do it. Before we start though, it’s important to know what environment cannabis seeds are most likely to pop in. Since in nature, they germinate in spring, logically, you want to put them in conditions that mimic fertile ground in spring – think plenty of moisture, little light, and mildly warm temperatures of around 18-22 C (64-71 F). Now, you’re ready to learn about the best ways to germinate cannabis seeds. Let’s dive right in!

Three Main Methods Of Cannabis Seed Germination

The following three methods have proved to be some of the easiest as well as the most effective. This means each of them is a great way to help your cannabis seed to sprout.

Germinating Cannabis Seeds In Soil

When spread naturally, marijuana seeds germinate directly in soil. So, why not recreate the natural process? This method is great for beginners because of how few steps it requires. All you need to do is make a 1.5-2cm (0.5-1 inch)-deep hole in the soil, place your seed in it, and lightly cover it with more soil. Then, water the spot above the seed and keep an eye on it to make sure the area stays moist most of the time. It’s also a good idea to cover your starting pot loosely with a plastic bag or a wrap to keep the environment humid and warm until the seedling shows up from the soil. This method is preferred by many because it eliminates the stress of transplantation that, at times, can be too tough on fragile seedlings.

Germinating Weed Seeds In Water

If you’re not ready to get your hands dirty just yet, it’s fine! Some growers start their seeds in a glass of water. This method is easy and quite effective. Practice shows that germinating in water normally makes around 90% of weed seeds pop. This method is pretty self-explanatory – all you need to do is place your cannabis seeds in a glass of fresh water away from light. Usually, the nuts crack open on the second day. For older seeds, however, the process may take up to 7 days, which is also fine. After the taproot shows, the seed is ready to be planted. Some growers wait for the seeds to drown (about 24 hours in), then transfer them to a wet paper towel – the method we’ll be explaining next.

How To Germinate Marijuana Seeds In A Paper Towel

This next method is a true classic that’s been shared grower to grower for generations. It’s also pretty simple and has everything you need to maintain the perfect environment for cannabis seeds to pop. To use this method of germination, place your seeds on a clean paper towel, fold it over them, and spray the towel lightly with water. After that, put the moist towel on one plate and cover it with a second plate to keep the seeds in the dark and not let the moisture evaporate. That’s pretty much it! This method can also be modified and improved upon. For example, instead of a paper towel, you can use two cotton pads for each of the seeds – these will be easier to open when it comes to removing the seed. Instead of plates, you can also place your seeds in an airtight container or ziplock bag to ensure the moisture stays in the towel/cotton pads.

How Long Does It Take For Marijuana Seeds To Germinate?

Your preferred method won’t make much difference in how long it takes for marijuana seeds to germinate. What actually matters when it comes to germinating cannabis seeds quickly is the quality of the seeds, their genetics, and how old they are. Normally, fresh seeds of good quality will never take more than 5 days to show taproot. However, if your seeds have been waiting for their hour for a little too long, it may take them around 10 days to germinate. Luckily, this won’t affect any characteristics of the future plant.
