will upgrage later just have one of these that i got for my wedding and have no need for it but want to get a few LG.

I dont see why not as long as you make sure there are no gaps for them to get out of. Also make sure you put breather holes in the tubs, but very small holes, many of them though. Also what are your plans for heating and humidity?

UTH. someplaces say Sand some say Aspen.
What would you suggest?

Where will you place the UTH?

There is no shelf to tape the UTH on which means you will have to tape it directly to the tubs, which could make it difficult to open and close the tubs, it would also mean that the middle tub would get heat from the bottom and the top, and finally it would not be very convenient when it comes to cleaning.

So while it might work it probably would require some modifications.

i was thinking for humidity a moss in the hide.
How would you suggest to heat?

I recommend indoor/outdoor carpet or newspaper. If you are an experienced leopard gecko keeper, sand is OK if you use a fine grade reptile sand. I do not recommend sand as a substrate for new leopard gecko keepers because new hobbyists may not recognize the signs of sand impaction (gecko eating substrate) which can be fatal.Keep two pieces of carpet on hand to make cleaning easier (when one is soiled, remove it for a thorough cleaning, simply replacing it with the second piece. When the soiled one is disinfected and dry, you can just swap them out again).

Paper towels are a great substrate for juveniles or sick lp geckos.

Substrates to Always Avoid
Wood chips, wood shavings, corn cob, walnut shells, and gravel are not appropriate choices for leopard geckos.

As far as the heat goes this could be a little hard dealing with that set up but I would think that a three inch flexwatt equipped with a thermostat would do the job. Install it down the backside of the rack. Make sure though that you have a thermostat.

For your humidity/moisture
Take a long water dish which I line with peat moss and pour treated water into everyday. To cover the dish and moss I have a half log over it. Geckos hang in the moss when they feel dry.

If you don't care about the looks, another really slick way to make a repti-sauna is to take a gladware type container, cut a hole twice the diameter of your gecko in one side atleast a 1/2 inch from the bottom of the container. Line with peat moss, and drench with treated water. Put the cover back on and place in the habitat. This will take care of the humidity needs of your gecko.

Goodluck!

The greatest Leo substrate, learned after 12 years, is actually slate tile. It spreads the heat well while not getting super hot, there's nothing to ingest, it's fairly easy to clean and it's relatively cheap.
Just make sure the tile is 'rough'. The glazed stuff is too slippery. :)

As for those drawer things... unless you used back heat I don't really think they would work out too well. Also, many of those units are a bit flimsy. You could try it, tho. :)
