Hey 10jed;
Don't know if it was my idea or not, I had seen other people use soil beds with good results so I thought why not make a hempy perlite bed? Its much easier to carry around than individual containers and gives each plant more room to spread its roots.
The dimensions are roughly 5" deep, 13" long and 7" wide. I placed the hole on the 7" side about 3/4" from the bottom.
