OSB is a type of ply wood made from compressed wood chips. You could use any 3/8 ply wood. OSB is cheapest. Polly is black and white plastic. Black on one side and white on the other. When your stapling the polly inside the table make sure the staples are on the out side of the table.If you have staples in the dirt they will rust. Rust isnt very good for your plants. Hope that answers you questions.

Tranoble Reviewed by Tranoble on . "THE SEALED ROOM" 3lbs A LIGHT THE SEALED ROOM Listen im not very good at writing this stuff down. You can post reply's with any specific questions and I will answer them best I can. My pictures of my room are 1 week from cutting down. Based On A 4 Light Room. Pictures are of a 8 Light Room. I start by sealing my room as best I can. From there I start by building a 8ft by 8ft box with 2x6. Then I screw 2 sheets of OSB 4x8 sheets to the bottom (sort of like a water bed box). I line the inside with polly making Rating: 5
