germinating weed seeds in paper towel and plastic bag

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.

Set the sealed bag in a warm area, such as on top the refrigerator, where temperatures are between 70 and 80 degrees.

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.

Gently water the soil with a spray bottle and situate your pots under a fluorescent lamp. Keep seeds away from the windowsill, as the temperature is too volatile for germination. In general, you’ll want to keep the temperature in the range of 70 to 80 degrees Fahrenheit.

The downside of water germination is that once they’ve popped, you’ll need to maneuver them into their growing medium manually. This is a delicate process, as germinating seeds are extra fragile, and any harm risks the development of your plants. Make sure to place the seed roots down in the soil when you transfer to a pot.

How to germinate seeds in soil

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.

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.

Soil is an easy, more natural method with which to germinate your cannabis seeds. The soil protects the fragile roots from any interference, and soil is, after all, where a cannabis plant would grow in the wild.
