Does anyone use a grow tent where the light hangers are curved?

I am in the market for grow tents, but I keep finding all these tents with curved light hangers and they don't look very sturdy. Does anyone know if this design is sturdy enough for the big hoods?

I'm not sure where else you can get them but on monstergardens.com they sell these Hercules framing kits for GrowLab tents. They are designed to slide over the poles for your new tent and they triple the load capacity I think. Just check out the tent section and you'll see them under GrowLab tents toward the bottom of the page. There is even a video. Someone on here had bought them before; you can do pullups from them.

that sounds pretty cool but I'm just trying to get 1 tent that's adequate

i have a 4x4 hydro hut....

i have a 8 blub t5 ,4" vortex fan and a carbon filter all hanging from them...seem strong to me

You never mentioned what you were trying to hang so I just assumed you were trying to throw a ton of shit in there. Any of those tents will support 1 of those XXXL hoods no problem. I just helped someone setup there 8x8 GrowLab tent and he has 2 Magnum XXXL hoods in there plus 2 Can 8" fans and some other little stuff. He didn't buy those Hercules supports and it seems to be working just fine. They wouldn't make a tent that couldn't support what you would need to grow in it. No one would buy it then.

I got my tent from HOMEbox (I've got the XXL) and I love the thing. I costs a bit but it's sturdy and well designed. The metal pipes that you hang lights from are above pipes going the opposite direction so the weight is distributed evenly across the frame (you can look at the assembly instructions to see what I'm talking about http://www.homebox.net/dhtml/product_family_homebox_l.php.) I'd be confident hanging heavy reflectors or carbon filters in my tent.

The smaller tents designed for one light are rated at about 110 lbs and the larger ones designed for two lights are good to about 220 lbs.

Oh apparently there is a Hercules framing kit for HOMEboxes as-well. I think you'd have to really try to need that kind of reinforcement for your growtent. Also it looks like they just replaced the plastic connectors with the same tubing the rest of the frame is made out of.

edit: I just realized HOMEbox is involved with the growlab tents. Neat, I'm sure it's as robust as the other HOMEbox offerings.
