My "grow room" is my living room which has a narrow clerestory and not much additional light. My living room is cool in the summer, but during the winter when I have my avocados indoors, there's not much light for them.

I want to put a reflective covering on my wall behind my plant benches... I don't understand the difference between Orca's light tight, and non light tight. What is the difference?

I see you offer "light tight" but it's the same price as the non-light tight at Orca's site... so I wonder how to tell the difference ...

Also, do you know if the Orca will insulate if there's an inch between it and the outside wall? I'm keen on that property.
