I'm new here but have been looking around on here. Currently in my first grow. just looking for all I can to help out. I got to thinking and wondring if you could build a growbox out of styrofoam? Not cheap styrofoam but heavy dutty commercial styrofoam? Seems like with it already white there would be no need for mylar/paint, and styrofoam allows oxygen to pass through it. It seems like heat issues wouldnt be as big of any issue, and it seems cheaper and a good alternative to a budget build. Anyones take on this?
