homemade grow tent? walls

I want to make a grow tent to reflect and hold all of the light in for a veg. tent. I am planning on about 15-20 3" pots to veg. I have (2) 2' T5 kit plus I want to add a 250 MH light. What is the best material to use. I do have mylar to layer the walls if I need to. Any and all opinions to get the best would be greatly appreciated

i have thought about making a homemade tent also the only thing that comes to mind is panda film its not to expensive u can get in like a 6 mil which is pretty strong thats what i would use im sure there are other things out there but the price compared to just buying one is prob not worth it u could just build ur frame and then wrap ur frame like a present then stick one of those zippers on the front and ur done hope that helps man ...widow

I'll check it out and see if i can find it on Ebay or if you know a place that has it for a good price lemme know please. I am running on a tight budget right now

I used black/white poly on a 3/4" pvc frame.

alright thanks the poly I seen was panda film so I will stick with that. Now I have to figure out how much I will need. Thanks
