Today I switched to 12/12. I'm going to be running the light from 10am to 10pm. The BH, BW, and BK clones are a 100 days old. The AK, SLH, and RD are 91 days old. I'm going to hook the HPS up tomorrow before the light comes on. These girls are big they range from 2 to 3 1/2 feet so I'm kinda worried about height problems. I'm planning on LST them to keep em short, just haven't got around to it yet. I was planing on starting the Fox Farm tomorrow at half strength with a little Grow Big in there for the streach. I'll probably just stick to their feeding schedule for now.
