I'm wondering if an emergency blanket is an effective material to line the walls of a indoor grow? They are relatively affordable, I found this listing on ebay http://www.ebay.ca/itm/New-Emergenc...in_0&hash=item4d05e84490&_uhb=1#ht_4145wt_986 and was wondering if it would work. It's pretty hard to dig through all the forums to find what you're really looking for these days. Thanks in advance!
From what I have read the emergency blankets produce hot spots. I read flat white paint was the cheapest and easiest way. I did that first then went and bought mylar from my local hydro store, cost about 25 for enough to do my 4.5x4.5 room.
I saw on a DIY grow box thread a guy used this stuff called panda film for his falls and flooring. It's waterproof and heat reflective
