How to Germinate Cannabis Seeds
The first step in starting your cannabis garden is to germinate cannabis seeds. Germination begins the life of your plants, so it’s vital to understand precisely how to do it. You must first ensure that the seeds you use are matured and viable. Mature seeds are dark brown with light accents and very hard. During the germination process, keep the seeds moist and avoid interfering with them. Seeds germinate best in warm temperatures.
Best Ways to Germinate Cannabis Seeds
There are several ways to germinate cannabis seeds. Here are some of the easiest ways.
Germinate Seeds Directly in the Growing Medium
This is one of the easiest and most common ways. The soil should have a pH of approximately 6. Supposing you use potting soil, do not add nutrients to the soil for the first two weeks. Ensure you plant the seeds a knuckle deep in moist soil, which is 1.5cm (0.6inches) deep. Place a seed into the already prepared hole and cover it with soil. Keep the soil warm with a heating pad or lighting. The temperature of the soil should be 22° Celsius or 72° Fahrenheit. Ensure the soil remains moist during the germination period. The seeds will sprout within 4 to 7 days.
The advantage of using this method is that the seeds will have minimal interference during the germination process. The hassle that comes along with transplanting seedlings into bigger pots is avoided. The process of transplanting can slow down growth and damage roots.
The downside of this method is that there is a risk of overwatering and overfeeding in the early stages. This can saturate the soil and make it difficult for the small roots to infiltrate deeper and become well established, leading to stunted growth and root rot.
Germinate Seeds in Water
To germinate cannabis seeds with water, fill a container with water, and maintain the temperature at 18° or Celsius 65° Fahrenheit. Soak the cannabis seeds in the water. We advise you to use a clear container to see when the taproot breaks through the shell. You should see the taproots emerging within 24 to 48 hours. The seeds must be removed from the water at that point and placed in the soil. Keeping them past that point may drown the seeds, although the seeds will still be viable.
The benefit of this method is that it can be used to differentiate viable seeds from non-viable ones. Viable seeds float the top of the water for some time before sinking. It guarantees the right amount of moisture to begin germinating and helps crack the shells of seeds that are too hard. Water germination also shortens the germination process by making it easier for the plant rather than pushing through the soil.
The disadvantage is that there is interference with the seed. Handling germinating seeds is risky because the roots can break easily. The plant might get stunted if not handled carefully.
Germinate with Paper Towels or Cotton Pads
Using this method, place the seeds at least an inch apart from each other in between two non-porous paper towels or cotton pads. Place them on a plate and cover the seeds with a plate to create a dark, protected space. Make sure the temperature is 22° Celsius or 72° Fahrenheit. Always keep the paper towels or cotton pads saturated. Check on the germinating seeds every 12 hours. The seeds will sprout after 1 to 4 days, although some can take up to a week.
The advantage of using this method is that the paper towels or cotton pads keep the seeds moist and protected. The disadvantage is that the seedlings are at risk of damaging during transplanting. The roots can also tangle in the wet cotton pads.
Germinating Seeds in Rockwool
Rockwool is a mineral wool made from volcanic rock and other materials such as basalt and limestone. You will need to add fertilizer into Rockwool before using it. The pH of Rockwool is 7, so you will need to lower it to 6. To reduce the pH, soak the Rockwool in water for a day. Ensure you wear gloves and cover your mouth when handling Rockwood.
The benefit of using this method is that it is cheap and easy to find. It is also ideal for hydroponic growers. However, there are several cons to using Rockwool. It is bad for your health and to the environment. Secondly, it has a pH that is too high to germinate cannabis seeds. It is also too complicated for new growers and has low germination rates.
Germinating Seeds in Peat Pellets
Peat pellets are compressed peat, which is made of partially decomposed vegetable matter. The pellets enlarge when you add water to it, forming a nutrient-dense medium around the seeds. Soak the pellets in warm water before planting the seeds. When the seeds have germinated, move the whole pellet into the soil or medium where it will grow.
One of the advantages of peat pellets is that it is already optimized for cannabis seed germination. It has a pH of 5.5, so there is no need for any adjustments. This method exposes the seedlings to minimal disturbances during transplanting. They have a high germination rate and are ideal for cloning. It is suitable for beginners. Its downside is that it isn’t suitable for hydroponic setups and must be soaked to enlarge each pellet before use.
Planting your Germinated Seeds
Seedlings that were grown using methods that require moving of the sprouts, they must be moved carefully. When planting, the taproot must be placed facing downward. It should be covered lightly. Avoid overwatering as it can attract molds to your crops. Use fluorescent lights for heat and lighting.
