Yes. Since the vegging state is on 18/6 and the flower is up at 12/12... the flowering part of the cabinet could get light interference from the extra light that the vegging needs so in order to prevent such things from happening, you need to isolate both sections from each other so they have their proper light lenght.

Totalpain Reviewed by Totalpain on . My kick ass grow room Hey this is the grow closet me and a buddy built today. I think it's pretty sweet. Under the big chamber is a little area for cloning, the ballasts, and some storage. Once the plants are ready to flower I plan to build a wall between the two lights so i have a flower chamber and a vegging chamber. I've got a room (2ft x 7ft x 8ft) with: 400W MH (on the right) 400W HPS (left) 100W T5 Florescent under for cloning lovin it, best grow room I could hope for only problem is my Rating: 5
