Hey everyone as you may already know I am thinking about getting into the UltraHighlands and need some questions answered. I am in need of major help in how to super cool my terrarium to 50-55F at night. I am out of ideas and need people's advice who grow these or know very effective cooling methods. I will be groing them if I ever figure out how to cool my 20 gallon terrarium. So these will be in a terrarium and 20 gallons isn't much but I need help BAD! Please give me some help! Thank You!
