It's the only thing i could think of . The setup i'll want this winter will consist of top and bottom shelves with the bottom shelf having vegatative seedlings and the top shelf having the flowering buds. So i'm guessing the bottom shelf will have lights on when i want to turn off the top lights for flowering .

The reason i'll want this setup is because i want to switch from indoors to out. The shelf table will be for cloning with the top shelf for mother plants and the bottom for the clones.
