b.real, if that black pipe is for plumbing, I gotta tell ya they're not the best way to join pipe in that they are very susceptible to leaks. Not implying you should change the fitting, but you might consider hanging a piece of plastic between the pipe and all that voltage. Also, it might be wise to ensure those power strips are elevated enough that if the pipe ever does leak, and water gets under that dividing plastic, it will not find it's way into the power strips and start arcing.
could there be noxious gas hurting his grow??
