wall surface

[buddog]

I have a building outside that i was going to build a grow room in. The walls of the building are made of metal like a zig zag pattern and has a dull aluminum with some shine surface to it. would this be a good color for light reflection or would white paint be better does it matter.

I would put up white polyvinyl (can be had at grow shops and hard ware stores I beleive) To ensure no light leaks..to ensure security if it was me. I think at Homedepot carries the black outside white inside stuff.

something along those lines is a rubber basement sealer that you can spray on with any water sprayer its not only fills in leaks but will insulate the room and can be painted . i cant think of the name of it right off but its in with the same things they use to tar in holes for roofing
