I'm 100% with you on this one but the room was conceived with an ebb 'n flow irrigation system in mind so bringing the lights closer is not possible: I'd have to drill new holes in the ceiling and relocate all the lamps cause now they're too close from each other. I'd also have to re-install longer duct and longer chains. I'll probably do that while the plants dry before next crop. I'll also buy a CO2 injection kit for the next crop to increase yield.

Thanks for the good comments guys! Realy appreciated:thumbsup:
