Galapagoensis enclosure

[Chilon]

Hello. So I recently got a 4 inch long S. galapagoensis yesterday and i got it settled on a big enclosure. It is a plastic bin that is 24 in. Long, and about 12 in. Wide and tall. No top ventilation but it has multiple holes in every side of the container this was to prevent humidity from escaping fast. So about 1/3 of the substrate is pure peat, other 1/3 peat and sand and the last 1/3 is pure sand ( i am using black desert sand by exoterra) the dry side is the sand and wet side is the substrate with peat in it. Would this be sufficient? There are 2 cork barks for it to hide in as well and I also need to know how will I heat its enclosure up without blocking any of the holes?
