Need help on my outdoor enclosure. My babies need fresh air and I hate leaving them in their tank when I have to leave the house. I'm building an outdoor enclosure so they can have more room, fresh air, and natural sunlight during the day. I'll take them inside during the evening to sleep and on bad weather days. I'll be adding dividers in my outdoor enclosure to separate the different species. I need help though. This is my first. The enclosure is 30 feet by 2 1/2 feet. What substrate should I use? I have a redfoot, yellow foot, leopard, and sulcata. They are all about 3 inches. What should I put in it? Is there special needs for certain species? I live in San Diego near the coast. Any tips and help would be great! Thx everyone!
