ok I started my grow with the wet paper towel and plastic bag. Now I have seedling, so I put them in my super cloner but really don't know if my lights need to be on 24hr, or 18hr on and 6hr off at this point? My seedling has grown about one inch out of the rockwool. I am working with a supercloset but the dvd is no help, it does not break the steps down. It explains as if everything is one process instead of multiple steps.
