I only use paper towel method..beware of frosts in next few days,not a big problem on my side of lake,but check weather broadcast for next days,should be last frosts of spring,cause weather is shite in Northern Europe right now....have to check my Ruderalis Indica seedlings,I put themstraight into prepared site..one thing for sure Sensi Seeds are mint..100% germination rate..and I got first time problem with Nirvana seeds..Hollands Hope got 0% germination...I would be really angry,if those were my only seeds..bloody angry..god luck Viking
