2 400w lamps both on for 20 hours a day one with a HPS and one with a MH. The MH lamp on mother plants and new clones 20/7 . The HPS lamp on auto-flowering strains for 20/7. but for flowering clones or possibly flowering mothers could i take them out of a dark closet across the room and put them under the HPS lamp at 11 am and then at 11 pm put them back in the dark closet? I know its alota work but its less work than another light and room. then across the room i have a cupboard that i planned to grow males (and breeding females) under CFL.
