Really? I was sure you would have said a thick layer of moss. Why? Because you have a deep box and succulents mostly only need moisture.... oh well.



I first saw this technique in a major magazine... and I have always like it.



I live in Florida and yes I still need to shelter or cover my succulents in a freeze that lasts more than a short time.



If you have any old wooden drawers, you can use them as well.



Oh yeah, why do you caulk the seams? I am thinking to hold the box frame together? I still would recommend drilling some air holes in the bottom. \



I do love this idea and a good one to build your own frame.
