Sorry guys and gals, life got busy, and the grow room had no room. Finally made some space and transplanted the Crescendo ladies into 3 gallons. They will sit in those for the next few weeks until I can move some more stuff around. Tangie cookies starts flower tomorrow so 8-10 weeks and I'll have plenty of space.
Update. The dimmer switch in the mars TSL-2000 has bit the dust (light flashing randomly). Contacted mars and they confirmed the dimmer switch is junk, and charged me shipping for a new one. For the mean time I reduced the light output using the drivers (pull the tiny rubber plugs and use a small phillips screwdriver) and disabled the dimmer function of the dimmer switch.
Got an update from mars hydro... Despite charging top dollar for shipping the part will take 20 days to get here.. Not impressed.
