materials needed

IF i were to build a grow box, what would be the best type of wood to use? Can the wood be able to take the heat and moisture and not build up mold etc?

I would just use some cheap OSB and then put Panda film everywhere in the room.

A good "guide" to follow : https://www.rollitup.org/grow-journals/81504-chill-winston-ggs-escape-paradise.html

Just change the black film for panda film and put it on the inside instead of outside.
