There are a few other substances that can be successful mediums for germinating cannabis seeds, and the technique used with any of these substances is the same as the soil method. Rockwool is a matted fiber material that is favored for its porous nature, and seedlings can be planted directly into it for germination. It can be purchased inready-made cubes for easy planting, and is readily available in home improvement stores.
An easy way to accomplish this is by placing seeds between layered, moistened paper towels. It’s best to use real rainwater for this method, and if you live in a rainy area you can collect rainwater in any receptacle left outside. If you don’t get much rainfall where you live, you can substitute bottled, distilled water instead. Moisten the paper towels with the clean water, making sure that they are not sopping or dripping, and place the seeds between the layers.
Check the seeds daily to make sure that the paper towels have not dried. When they begin to dry, simply pour more water on them and squeeze it out gently. Do not let standing water accumulate in the bag or plate you have placed them in. This process should take between five to twelve days. Sometime in that period, you will see the seed casing burst, and a small but strong root will emerge.
The Straight-To-Soil Method
Purchasing seeds online is the best way to get a good, reliable cannabis plant that will have the best chance of producing buds. You may find seeds in your regular product, but the chances are good that those seeds are either dead or dried out. Dry, old seeds are extremely difficult to germinate. Those seeds in your bag are probably pretty dark and dull looking, and that’s a sure sign that they are either dead, or old and dry. Healthy seeds bought online will look fresh and waxy, and that’s how you can tell that they are young, healthy and ready for germination.
Wherever you live, the springtime is when you see incredible plant growth and new, green life sprouting up all around you. The key to successful cannabis seed germination is to replicate a spring-like condition for the seeds, inducing them to vegetate. This means that seeds should be moist but not soaked, and warm but not hot.
An another great way to germinate cannabis seeds is to use a seedkit. For an excellent explanation of how to use the seedkit, go to Zambeza Seeds.
Growing cannabis from seeds is no more difficult than growing any other plant. It doesn’t take a magic touch or a green thumb, and it doesn’t require special knowledge of horticulture.
Stack two paper towels on top of each other. Fold the towels in half and sprinkle them with water until they are completely moistened but not dripping wet.
Slide the paper towel into a plastic zip-top bag. Seal the bag closed to trap the moisture and prevent the towel from drying out.
Things You Will Need
Spread the seeds out on top the paper towel, covering only half the towel with seeds. Space the seeds so they are not touching and there is about 1/4-inch of space around each seed.
Plastic zip-top bag
Fold the damp towel in half, sandwiching the seeds between the towels. Press lightly on top the towel so the seeds are in full contact with the towels on both sides.

Whether you’re planning an indoor cultivation or outdoor grow, it’s best to germinate your seeds indoors. It’s easier to maintain proper temperature, light exposure, and moisture inside, and you can protect your seeds from the elements. Indoor germination, whether using soil or paper towels, will ensure your cannabis seeds have the best chance for survival.
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.
To germinate seeds this way, lay one paper towel on top of a countertop, place a few seeds, and cover them with a second paper towel.
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. Maintain a temperature of about 72 degrees Fahrenheit, keeping the paper towel wrapped seeds in the dark and away from a windowsill. In two to five days, the seeds will pop inside the paper towel sandwich and emit tiny roots, ready to plant when they reach about five millimeters in length.
To germinate seeds indoors, use any of the methods described above. Within a few days, you’ll have popped seeds ready to transfer to a growing medium.
Germination itself is a crucial aspect of cannabis cultivation. The seed germination process is the foundation of every marijuana plant, and steps can be taken to boost successful popping. For example, some cultivators improve germination attempts by soaking seeds in 1% hydrogen peroxide or a compost tea for 12 hours beforehand to kill any dangerous pests.
