A bit of background before I ask for advice. I got a baby Sulcata on Sept 30, 2016, his weight was 62 grams. This was my first tortoise so I read a lot of information on this site and built him a indoor enclosure. The enclosure is 8' X 3' X 30", temp kept at 80-82 degrees and humidity at 76-78%. He currently weights around 15 pounds and measures 15" from the front of his shell to the back of his shell and 15" from one side of his shell to the other (almost sounds like he's square ha ha). We soak him everyday, which he totally loves. The way we know he is a male is from time to time when I pick him up out of the water his manhood is hanging out!! I live in the Dallas Texas area and want to build him an outdoor enclosure. I have two ideas and wanted to get your advice. I was thinking on building an "enclosure" (night box) and putting it on my patio with a pig blanket and hanging ceramic heater (I know this would be temp until he got bigger) or building a insulated shed (not sure of size but would take suggestions) with pig blanket and heater (please suggest type). I don't have any trees large enough to put the shed under so it would get pretty hot inside in the summer months (temps range from 90-100 during the day and in the low 80's at night). Is he big enough to stay outside? Do I need a AC/Heater to keep the enclosure in the 80 degree range? Does the enclosure need to have a humidifier?
