I have a tray with a heating pad, I want to germinate my seeds in rockwool and keep them in the tray. how much light do they need and when is a good time to transplant them to my waterfarm?
2-4 23w cfls are fine. transplant when there are well rooted. Or just stick the rockwool right into the waterfarm and hydroton and put the light on that. Have done it both ways.
