You will rarely get better advice than from the Big Finn! There are many other building materials you can use better than cardboard that have reflective and insulating qualities, not to mention may be more fire resistant....mylar covered foamboard comes to mind right away! Take a walk thru a big building supply store and see if you get inspired by anything! They seem to come up with new insulating board all the time, and the insulation and sound deadening properties will help your grow stay stealthy too.
TANKJR Reviewed by TANKJR on . Too Hot? Please help a would be newbie I am planning a cardboard box grow. I am thinking about using 6 23w cfl's. The problem is I am seeing flashes in my head of me sitting in a squad car wondering how I am going to explain to my land lord why her house burned down. So, naturally I am wanting to hear from other cardboard/cfl growers if this is a well founded fear? Rating: 5
