Monitor your soil every day and keep it moist. Within four to seven days, you should see tiny stems sprouting from the 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.

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.

While many plants can be germinated in the ground, cannabis seeds are fragile enough that you should germinate them before planting.

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.

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.

Keep things dark but turn on your grow lights at the first sign of sprouting. Once the seeds have sprouted, you will need to provide plenty of light. Preferably, they should receive it 18 hours a day.

If it has been well over a week without any signs of a sprout, it is likely a dud. Germinating cannabis seeds requires patience. Keep in mind that the method you use can influence how long it takes.

Do Cannabis Seeds Need a Light or Dark Environment for germination?

The early development stage requires things like warmth and a gentle touch. You can approach germination in multiple ways. A couple of them are better than others. This article will provide you tips and other helpful information on how to germinate weed seeds. Soon, you will have many healthy cannabis plants growing.

While cannabis seeds primarily need to remain moist, you can soak them in water overnight. All you need is a glass cup. Fill it with three-quarters of a cup of water that is filtered or pH neutral. Make sure the temperature is neither cold nor warm. The ideal temperature is lukewarm.

Here is an explanation of each germination method.
