DIY Planter Humidifier
Increase the humidity in your reptile or hermit crab’s cage! Select an unglazed clay planter that has a hole in the bottom. Find a large sponge that will fit inside the planter. Hold the planter and sponge under water so that they both become soaked. If needed, wring out the sponge slightly so that it is not dripping. Set the planter upside-down in your terrarium with the sponge inside. Soak the pot and sponge again as needed.
