Hi I have been looking into getting a Savannah monitor for quite some time now. After all my research I have determined what I need but I am still confused with some things. My questions are, How do I build my enclosure (8'L 4'W 4'H)? Do i use plywood and some sealant? Do i used Plexiglass as a way to see in? I am really not sure... Also, What substrate should I use? I keep seeing people saying a mixture of sand and soil but I don't know which soil to use as i don't know of any brands that sell completely organic soil. Thanks for your time!
