the only thing I would change is the Styrofoam.

cuz I built a Styrofoam grow box a few years ago. It was 3 feet tall by 2 1/2 feet wide and 2 feet deep. and it burned cuz 1 of the 9 cfl light was tuching it and then fire happend.

now I use the huge rubber tubs as a grow box.

well good luck on ur new project.:thumbsup:
