The paper towel method also has its risk, as the fragile seedlings can be damaged during the potting process. The tiny roots can also get tangled in the paper towels, so make sure to move the seeds to potting soil before roots grow too long. Use your hands or tweezers to gently remove each seed from the paper towels and place them in a prepared growing medium.
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.
The paper towel method is also a common way cultivators pop their seeds. Some even use this method with cotton pads instead of paper towels, but the necessary steps are the same.
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.

The best germination method depends on the cultivator’s choice. Here are some of the most common ways to pop your cannabis seeds.
Use a spray bottle to moisten the paper towels and then store the cushioned seeds between two plates, under a face-down bowl, or gently place them in a plastic bag. Photo by: Gina Coleman/Weedmaps
How to germinate seeds in water
When the seedling stems reach two to four inches in height, it’s time to transplant your cannabis into larger pots with more room for roots to spread down and out. After you’ve done this, you’ve successfully germinated your cannabis seeds into proper, young plants.
While many plants can be germinated in the ground, cannabis seeds are fragile enough that you should germinate them before planting.
In reality, without a successful way to germinate seeds, you’ll have nothing to work with.

However, this is not always the case. Depending on the species, seeds can stay viable for quite some time. A date palm seed that was around 2000 years old germinated several years ago, making it the oldest seed to germinate. It was stored in hot dry conditions, shocking it was able to germinate!
Cultivating cannabis from a seed is not as easy as many beginner growers might think. Various factors are involved which will ultimately determine if the cultivator is successful and has a large harvest, or if they fail and have to go back to the drawing board. Learning how to germinate cannabis seeds is the first step to becoming a cultivator.
How Do You Know If A Cannabis Seed Is Viable?
Watching a cannabis seed germinate can be a lot like waiting for water to boil — it takes time (typically a couple of weeks). The seeds will eventually crack open and a white root will shoot out of the cracked cannabis seed shell. The white root is often referred to as the taproot. Once your sprouting seed has a strong taproot (an inch or so) it is ready to be transplanted.
When Is The Seed Ready To Be Transplanted?
Germinating marijuana seeds is not difficult, although it does take attention to detail and the right environment. Successful germination takes the right amount of moisture, the right temperature, and a decent amount of light (sunlight or artificial light from low-intensity grow lights).
