Reptile & Amphibian Forums

Hello, this is my first post to this forum so I'll try to make it decent (with decent spelling, too
I currently keep 2 sav. monitors (Savvy, 4.5" SVL & TinkerBell, 7" SVL), and have had them for 2 months now. They are currently housed in a 8'x6'x6' enclosure, with 3' of dirt as substrate(I just dug it up from my yard, I live on a BIG farm in Ohio, and am certain there are no toxins or pesticides in it). the lowest ambient temp is 78F, with multiple hide and basking spots, the warmest one being 146F at 12" from the lights, at a 14" circumference, which seems to be enough for both of them to fit under. The humidity ranges from 50%-70% throughout the cage.
They are fed dusted crickets, free-ranging grasshoppers, and pinkie mice daily.
I was wondering if it would be feasible to plant their enclosure(I was just gonna do grass, thinking it might keep the humidity levels more stable), and I am aware they are burrowers, as mine have demonstrated, since that was the first thing they did after being brought home.
Also, where does the name "bosc monitor" come from? I know my literature on them is very outdated (National Geographics magazines from the 60's and 70's), but I found more valuable info in them than those pet-store quality books (like TFH and crap).
Also, since I am considering acquiring an Ionides, and setting him up in their current enclosure, I was wondering if it would be possible to house them in my greenhouse, since it is not used very much, and is heated throughout the year(It is about the size of a barn).
Thank you much for any comments.

P.S. Sorry for such a long post, but I just wanted to make sure I had all the relevant info listed.

They were named for John Bosc, as the term savannah monitor describes any one of many monitors throughout the world that are arid to semi-arid grassland monitors. Savannah monitor is a pet shop term that caught on but as I said encompasses many animals. An albig could live in and enclosure that big for a long time and most people dont provide near that much space anyways. I wouldnt worry about grass growing because the people who have it growing in their cages have other problems either too wet, extrememly lazy animal (they destroy any plants). I dont know how warm your greenhouse is and Id suggest 2 basking sites and hides for 2 monitors so they can get away from each other.
