No problem broomer5.
What do you want to do for lighting? If you want metal halides, than this canopy is a definite no. It works for the VHO's and PC's, it's just not the best design for it. With the icecap thermal sensing fan I have, it actually stays fairly cool under there, even with there not being much clearance. I want to build a canopy that has doors on the front so I don't have to lift the lights when feeding, etc...
Another heads up, the 48" VHO's, with the water-tight endcaps, are a very tight squeeze between the ends of the canopy! You could probably slide a piece of paper between them! <img src="graemlins//eek.gif" border="0" alt="[eek]" />
