I just got one of these yestarday and I acclimated for 2 hour, and placed in my sand bed. I noticed couple hours later that it was expelling some kind of clear strings of some sort. The OB was under 1 250 MH and thats it. Now OB is under 2 x 150 HQi and 2 x 130 dual actinics. Also are all OB supposed to be dark at the base and green or whatever colour highlights? Because mine is pretty white/tan at the base, but good green flourescent colouring.
