I love these Veradek planters so much that now I own 6 of them. I started with the taller style that has a removable self-watering tray and liked them so much that I purchased 4 of the smaller style (not self-watering). All came with styrofoam insulation, inside, on all 4 sides and a removable plug in the bottom for drainage. They are beautiful, sturdy, and my plants love them. Even through snow and ice my plants stayed warm and cozy. I'm going to plant patio tomato plants in the 2 that I just purchased.
