me again

hey guys got another question for ya's i have to change my room set up is it ok to use 4ml black plastic for the walls of my room with mylar or some other reflective on the inside? and should i make it a little bigger to walk into or just big enough for the plants? thx again

Its all personal preference...... Depends what your doing.... Be careful near the walls if you are only gonna use plastic and mylar for walls.... You could buy Panda plastic which would be white on the inside and black on the opposite..... I believe Panda is at least 5 mil for the cheapest stuff.... I like walking in my room. I didnt see your other post so I dont know any of the other specs for the room/
