Which is better? It depends on who you ask...

Some growers swear by the 24/0 schedule, saying that growth is more explosive, especially a couple weeks into veg. Others say that roots experience the most efficient growth during dark periods. I don't think either explanation is written in stone, but neither seem to be all that harmful to the plants.

I've tried both, and didn't really notice much difference either way. I prefer 18/6 now, if for no other reason than the undisputed fact that it saves me money on my electricity bill. :jointsmile:
