DIY Planter Platform Cave

Use planters to create a basking platform with underwater caves for your pet turtle! Cut out a portion of each planter for a cave doorway and cut out a dip along the edge of each planter base. Place one planter base upside-down, use aquarium silicone to glue a planter cave onto the base and glue the second planter cave on top. Attach the second planter base on top of the structure, fill the planter base with rocks, and set a piece of tile on top of the rocks.
