I was recently given a bunch of free plywood, so I decided to use it to build a grow room in my basement. I only had to put 2 walls up and they are nothing special. I’m now at the point where I have to decide what to put on the walls. I’m trying to keep it on the cheap side. So how dose white paint compare to panda film or poly ? Also I have a few shelves in the room, should they come out? Or will they be fine? I plan to get another light and possibly use the whole room or run my tent in the room and have plants in the tent and in the room. I don’t know if I’ll be able to have one in veg and one in flower. I do have a window in the room and I want to seal up any light leaks so I’m leaning more towards the panda film. What’s the cost to cove about a 10x12 room?
