The answer, unfortunately, is no. You can’t pop your cannabis seeds submerged in water. As you might have guessed, water actually inhibits the germination process. The purpose of soaking your cannabis seeds in water is to soften up the outer shell and prepare it for germination. This process also allows air to enter the seed’s embryo, which contains all the nutrients needed to start a new plant. While it’s true, that soaking helps get seeds ready for germination, it doesn’t actually do anything to help them grow after they’ve sprouted. That’s why you should do everything you can to avoid letting your cannabis seeds stay submerged in water for too long. If you’re going to soak your seeds before planting them, make sure you remove them from the water as soon as possible so that they don’t have time to develop mold or other harmful pathogens.
