How to grow marijuana seeds with 100 success rate. Day #1 br br I have tried many other seed methods such as the paper towel method and too many things can go wrong especially if it's your first time. br br This is a fool proof way to pop seeds and be sure they will grow after the marijuana seed has "cracked." br br If the marijuana seeds splits open like a clam shell it will grow into a seedling, if not I still plant them and have had about a 50 success rate. br br The seed strains we are popping are Northern lights x big bud, skunk #11, LSD, white lavender and northern flame.
