I am moving my operation into a new area of my basement due to the fact that growing in the mechanical room can be nerve wracking I had a guy from the gas company come over unannounced who had to check something out on my water heater yesterday and i made him wait upstairs for about 5 minutes while i dismantled the room the best i could. He couldnt tell. But my wife got scared and gave me another area which is much bigger. My question is I have to build a wall to hide the room and also a wall inside to seperate veg from flower. I am in the construction trade therefore i have no worries about building walls power ventilation and all that i just dont know if i should use drywall and paint it white or if i should use the foam insulation with the foil? both are very close in cost and both are easy I dont like painting but if it will help I will do it My wife also didnt like all the extension cords and flourescent lights hanging all over so she told me to get a better light I will be ordering my HPS next friday sorry for the rambling question and i appreciate any answers

If both of them are easy,
and the both accomplish the exact same thing, one no better than other,
and they both cost the same...

Flip a coin!

mylar is going to be a hell of alot easier to hang, but if I read correctly, your going to be sheetrocking your false wall anyway. I'd go ahead and sheetrock it, you can always mylar over it if it doesn't meet your needs.

High, I am going through the same process of moving and enlarging my grow area. Everything that I have read says to paint flat white. I was thinking that some sheetrock is nearly a flat white to begin with. I am going to try just going with sheetrock un-painted at first. I have also read that foil can actually focus light in some cases and burn plants. I don't know if this is true, but it scares me enough to go with flat white.
