If i were to change the lighting schedule, i wouldnt do it until they have a couple sets, then change to what you want. I think its more of a personal choice
whatsthatsmell Reviewed by whatsthatsmell on . Seedling Question How tall should seedlings be? I have a few that just sprouted yesterday and I don't want them to stretch. The CFLs are about 4 inches above them; too far away? Also, when is a good time to switch from 24 to 18/6? I don't want to do it too early because I have read that it might cause stretching as they stretch out to find light in the dark. Any help would be greatly appreciated. Thanks! EDIT: The CFLs are the big 150W equivalent. Rating: 5
