Hi all! I'm looking for some advice on my outdoor enclosure for my two redfoot tortoises that are about three years old. I live in SW Florida. I just finished extending my Lanai for them. Their main house is always accessible for them but it's under the covered part of the Lanai. I'm going to make a large concrete water bowl, plant more edible plants, and make sure they have deep shade. My biggest concern is what to use for substrate. I definitely want a variety for them. Maybe some grass and cypress mulch. What else would be good? Right now it's just natural dirt and some old cypress mulch. I know orchid bark is good but think it may be too large of an area and not cost effective? I also plan on hosing it down once a day to keep up the humidity. If you have any suggestions I would appreciate it! Thanks!!!
