Wasn't sure where to put this thread. I need ideas of what to use to raise my pots 2" off the ground to keep the water flowing. I had to put a carpet in my grow tent to keep the container from sucking up the cold from the concrete floors. I was thinking of buying 5" square tupperware containers and drilling holes in them. I don't want them deeper than 2-3". This will be fairly expensive option though. Anyone have any ideas for cheap drainage? I thought about going to buy some fencing and bending it to what I need. That just seems like a lot of work for nothing.
