soaking marijuana seeds should sink

In general, growing cannabis from seed can offer the opportunity for growers to possibly create something new which can be exciting and different. Besides genetics, phenotypes based on the grow environment can create different alterations of the same cannabis strain (Conviron, 2017). An individual can easily purchase seeds online or by pollinating and hybridizing one’s own seeds for use. Cannabis growers may find more success by first floating or soaking their cannabis seeds in filtered water, than planting directly into a growing medium.

The germination of cannabis seeds depends on the right amount of heat and moisture (NGA, 2018). Since viable cannabis seeds float on the surface of the water, they are able to retain the proper ratio of moisture and air. Seeds that do not float may be sterile or underdeveloped. When you roll the seed in your hands prior to floating the seed, it should be firm and brown with the occasional dark stripes in appearance. Immature cannabis seeds appear green or sometimes white and as stated above they will sink to the bottom when you attempt to float them.

These cannabis seeds were floated in 8oz white paper cups covered by a pot tray. These cups were then placed under a T5 light approximately 1ft away from the tops of the cups.

Other than drying out over time, one disadvantage of the paper towel method is that there is a chance of hurting the taproot. Be careful when checking on the seeds, and do not move them too much.

Some people use paper towels right after the water soaking method to get the remaining seeds to germinate. You can use paper towels from the start as well. The first step is to dampen the paper towel and put it on a plate. Place the seeds on it before folding the paper towel over.

The life of a cannabis plant begins in the germination stage. It finally starts to sprout after a period of being dormant. Even a seed that is a few years old can become a thriving plant. Growers need to provide special care when trying to germinate weed seeds – like they do with any growing plant.

Wet Paper Towels (recommended)

There is more than one way to germinate weed seeds. Each one comes with its benefits and disadvantages for growers. Common methods are:

Next, place the cubes into the bowl and let them soak for one hour. After an hour, take the Rockwool out. They can maintain the correct water-to-air ratio, so it is important not to squeeze the cubes. Like regular starter cubes, Rockwool usually comes with holes already in them. If not, make one that is a quarter-inch deep. Carefully insert a seed and push them to the bottom. Cover the top of the hole and wait. The seedlings finish germination in an average of three days.

However, the Rockwool method also has some drawbacks. The material does not break down since it is not a natural substance. As a result, the cubes are not an eco-friendly option. Rockwool has poor germination rates, and it comes with a high pH level. The material also can affect your health. The Environmental Protection Agency found that the fibers in Rockwool can irritate the skin, eyes, nose, and throat. You may experience a sore throat or coughing.

The seedling plugs and cubes already come moist. However, the setback is they dry out over time. Once you open a package, you have over a week to use them. Many products do not provide less than 50 cubes. If you plan to germinate only a few seeds, you could end up wasting a lot of cubes. Therefore, this method can be less cost-effective than others.
