Planting marijuana seeds in dirt

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.

The best germination method depends on the cultivator’s choice. Here are some of the most common ways to pop your cannabis seeds.

When a seed enters an environment with enough moisture, it will increase in size and slowly break out of its shell. A seedling or germ forms from which roots will emerge, helping the baby plant absorb nutrients from the soil. Seeds naturally develop roots facing down and stems stretching upward, allowing the young cannabis plant to simultaneously feed off light and earth.

The seeds should start sprouting in about two days, though older seeds can take up to a week to sprout. You can remove them from the water and place them in the soil at any point once they’ve sprouted. Once the roots are about five millimeters long, they need to be planted.

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.

Preparing to germinate cannabis seeds

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.

First, make sure you use the correct type of soil, either gently fertilized potting soil or a seed starter with a pH level of approximately six (6). The soil contains the right acidity and enough nutrients to strengthen your young cannabis plants for the first two weeks. Be careful not to add more nutrients, or you risk overfeeding and killing your seeds.

When you use normal kitchen foil, poke some holes through the foil. This will avoid the risk of overheating and let air flow true.

Cover your pot(s) with kitchen foil or microwave foil (with the small holes). The foil will act like a small greenhouse, keeping the inside of your pot warm and moist. Perfect for germination.

Step 5: Cover the pots with kitchen foil

Prepare your pots with clean fresh soil. It is often easy to use small pots for this, and transport them to a larger container later.

Make a small dimple in the soil and place the seed 3-5mm deep inside the soil. Don’t bury your seed too deep! When you put your seed too deep inside the soil, it will struggle to reach the surface, and have a high risk of dying before it does.

Make sure your soil is wet, but do not soak it. It needs to be damp but not soaked, otherwise you risk your seeds to rot. In most countries, normal tap water is clean enough to use. Do not add any additives to the water.

Step 4: Cover the seed and press gently

All 5 seeds germinated in 4 days within 24 hours of each other. You can now place them under a grow light, behind your window or outside (during spring / summer of course).

Cover the seed with soil and press the soil gently.

Take great care handling seed and seedling. Most flower and vegetable seeds are simply planted directly in the soil, but because of the value of cannabis seeds, germinating seeds prior to planting is encouraged. Growers can achieve a much higher survival rate by germinating in a non-soil medium and then transferring the seed to soil once the tap root has emerged from the seed.

Under the right conditions, seeds usually open in one to five days, so check them daily. Do not allow the towels to dry, and add water as needed to maintain moisture. Some seeds can take as long as 10 days to germinate, but if seeds have not opened within 10 days, they are not viable.
