You could do a strip as you say, but if you add water to the bottom of the sub via a tube the top of the substrate will stay dry and the roots will find the moisture below. This mimics nature as if your T burrows the substrate will have more moisture the deeper it digs, if it hits the bottom it only finds rounded pebbles , nothing that will hurt it. My arid scorpions are set up in a similar fashion , the substrate is bone dry on top but moisture is available if they dig. People seem to think false bottoms are for maintaining high humidity, where they shine is when you want arid conditions and low humidity, a burrow will have humidity which the animal can regulate itself by digging deeper or by moving closer to the surface just as it would in nature. Most people add too much water to a false bottom, I add just enough to stop the pebbles drying out completely, a couple of shot glasses a month is usually enough. You could localise it, but as long as you just add water via the tubes your substrate will stay dry on top.
