Have been watching your cloning deal, is a very important part of my deal, I try and keep it simple and cheap. But left dirt for oasis cubes, like tenacious jell rooting compound, use cover no dome(very leaky dome) to diffuse light**, water (distilled) every 6 hours have timer, reservoir sets under tray for drain out and has aquarium heater to maintain proper heat. This allows me to do couple of hundred in a small cabinet
