Need Help - Grow Tent Caving In

I have a 10 x 10 Secrete Jardin Darkroom. Im hanging 4 Radiant 8 1000W HPS systems but I believe these are too heavy for the tent, even though the instructions suggest this tent is for four 1000W HPS lights. The center of the tent bows ALOT. Im afraid if I leave them up it will eventually cave in. Can anyone think of some ways to support the center of the tent? Some kind of a stand? I cant find anything online. Any help or suggestions is appreciated.

need some pictures to see what were dealing with......

Just put a support under it. A properly treated 2x4 would work.

I'd chain and bolt it some how to the ceiling!

toggle bolts are typically my answer to everything, a 2x4 would definitely work, but if you were to use 1/4" toggle bolts in the ceiling of the room your tent is in, and some wire, cable, string, or whatever to tie around the center support rods on the tent, you can fix it for literally a couple bucks... you can get em at lowes or home depot, or just about any hardware store... youd also need 1" fender washers with a 1/4" hole... the toggle bolts are rated to hold something like 75lbs or so i believe... chances are the sheetrock would give away before the toggles would... or, you could get some 2" pvc, as its dirt cheap, and cut it to lenght, then get a fitting that would allow you to screw it into a 1x12 or something for stability...
