I second everything tiny has to say. RW holds moisture veeerrryyyy well. I only flood twice a day because any more and i run into overwatering issues.

Personally i dont like to run my lights at 24/0, ive noticed better root growth during 18/6



your gunna want to bump up the lighting though, any longer and youll notice stretching and your seeds will become very lanky. I would opt for a 6400K or 6500k bulb, it emits more blue light which is more beneficial during the vegetative phase. Plants need the blue light in order to stay short, stocky, and bushy.
