A few days max. You should not have to water for a while because you dont want the soil too wet, just moist.they are planted. used an entire water bottle on all four party cups. htey are udner me light. how long you think they will take to break through the soil?
At this point you cant go wrong with 18hrs on. It really does not matter until they break ground but 18hrs is a good place to be.wht lighting schedule should i use
