For freshly cut clones, give them ambient light only. Do not put freshly cut clones under direct light. When you see roots, THEN you can gradually give them more light. When you see new growth, you can give them full light with the rest of your plants in vegetative growth. The light cycle for clones should be 18 hours on, 6 hours off. The mother just make sure it's 18 hours of light per day.
