Inside the Greenhouse I have made one of the wooden framed beds into a bog garden to raise Carnivorous plants. The center is a pond area that serves the frogs well and they are free range frogs so they travel throughout the greenhouse eating bugs and are very happy. The bog is lined with pond liner to keep the sphagnum peat moss moist and it absorbs water from under as I pour pond water into the sides of the beds. Avoiding potting mixes with added fertilizers greatly increases the chances of Carnivorous plants surviving as well as not handling the plants. My next step is to build a cover for the entire bed suspended with the ability to move since the constant direct sunlight on terraria can produce high temperatures capable of killing the plants.
