Hardon, Del and Bob, thanks for the info i have two computer fans installed in this small closet box. One at the top and one at the bottom. Agreed 2 20w flors are not enough but this was for starters. Today i'm putting 175 w mh. Got to figure out to set up. Bitch is heavy with the ballast installed in the unit. Think ill go to the depot and buy some chain.
Thanks again, ill keep you posted. Sorry i don't have picture capability.
