I didnt put on the hoods ,they are to wide. I have 32-33" from pipe 2 bulb. I also have the stands pre-fabbed for 5 more pipes. Im looking at doing 10 pipes now and a small space between in the middle. I have a low profile container with ropes on either side to help move large amounts of light weight gear from one end to another. I took down the pipes and placed them on far end to do final lighting, wiring, venting and floor to roof clean. It only took 15 minutes to disassemble and move since i made the stands 2 piece now. I got all ballast screwed up top and 80% wire clean n neat. All wire is run threw the joices so its very tidy and completely out of site and out of the way.
I have 1 1000 watt burning with a 7" air king clip on just blowing threw it and you can touch it. Its pretty warm but no problem holding your hand on it for a few seconds. With 1100 cfm cooling just the bulbs , im sure they will be very cool to the touch. I got some fogger type fittings I may install in every other joist as well , so if i encounter anything that needs to be sprayed it will make a breeze( probably getting a head of myself).I'll take some progress pics tommorow, heres something to look at of some other nightmare room 4'x6'x8' 2000 watts 30 plants,scrubber and 2 38" tall fans, underfloor intake AND exaust. Intake was rooms dimensions boxed and plumbed outside exaust was 6"-10" for smooth flow due to a 90 degree elbow then exited out of intake box then 15' to outside.
