I have a Big Bud sprout in a rockwool cube, in hydroton, with the air pump running inside my tent. Im using a 400w MH air cooled reflector, should I have it on and pulled up to the top of my tent until I see leaves? Or does it not need to be on at all? Also, the same goes for my water pump. Should I be watering the cube in the pellets before I see a leaf?
