Frigaultanswered grow question 4 years ago Yes otherwise the water will catch onbfure and burn your house down.... Just kiding.. no it isen't necessairy... Just put it in a dark place at around 22 degree celscius. I use my washroom cabinet.. just remember to remove it pass 48h or they may drown du to lack of oxygen. And put in soil regardless if it cracked or not.. .. after futing is soil you can mist but don't water if soil seems dry.. that's about it. Yiu can flip a see thru cup to maintaint humidity. I just mist a little. Seedling needs to find theur water by diging for it..
