what size PVC Pipe for a 1000W or 600W HPS Grow Tent?

1st Question: Is a 5'x'5'x7' room a good size for a 1000W HPS? Is it too small for a 600W HPS? I am going to start with the 1000W but may move to the 600 if it ends up being too hot.

2nd Question: What size PVC Pipe should I use for the tent? From doing some research it looks like I will go with the 1" pvp pipe and split it probably 3 times to be strong enough to hold the hood and exhaust fan. Is a 1" PVC Pipe with 3 breaks in it so it flexes less enough to hold a 1000W HPS Hood with the exhaust fan?

Here is my story if anyone cares.

I am in the process of constructing a PVC Pipe grow tent to house a 1000W or 600W HPS light. I have both lights and prefer to use the 1000W but I may want to go to the 600W if it proves to be too hot. I am not 100% sure what size pvc pipe to use for the tent. My plan was to make something like a 5'x5'x7' tent which is going to be my flower room. I was going to go with 4-6 plants in soil but may move to some type of hydro later on. This is not my first time growing. I was forced to take down my nice grow boxes that I made from wood so I want to make something less of a hassle to take down if I have to again.

Thanks for the replies!

Bump.

Any advice?

I guess this should go in Grow Room & Design forum.

My bad.

I recently built a tent just like you plan.

i split the shit out of it. had a split every 6 inches.

by the time i was done i ended up paying almost 90 bucks just in pvc. it goes quick when you are tryin to make it sturdy.

if i can make a suggestion.

dont use pvc. plan and simple it sucks. it also allows gassing with temps over 82f

wood is the way to go my friend. if space isnt an issue and you have the tools i highly recommend using 2x3s and panda film. if you need something strudier than panda film. you can use 2x3s and reflective insulation board, 2x3s are usually 2 bucks a piece and the insulation board will be about 8 bucks for a 4x8 sheet of 1/2 inch. 1/2 inch allows light seepage. 1 inch does a better job. i think thats like 15 bucks a sheet.

I'm with Johnbo....go with 2x3. I used 1" PVC for my cloning/CFL tent which was only 4' x 2' x 4'. For my grow I used 2x3x8 which was $1.49 a pop at Home Depot. My grow is 3'x5'x7' and running 600 watts HPS. For yours I would go with a 1000 watter.
