My rack is melamine, walls on either side. Front and back are open. The back has the wires for the flexwatt (I use them along the rack, not sideways, so the wires go out back). Now I know people have even racks with only "pillars" with no side walls and clear tubs inside with no problems. I have now and then a problem feeder. I don't know if the open back (which is close to a wall but not completely agaist) has anything to do with it? Would the light, although hardly any, on the backside of the clear tub make them less secure?
Perhaps I can cover the back with something. Can someone suggest some way of doing that? I won't be using melamine because the thing is heavy enough already, and the wires and the stoppers at the back will not be redone it is too much work. I need something that perhaps block light, will not disturb the snake, and flexible to cover it. Not cloth though because I don't feel comfortable with cloth that close to the heating elements. So I guess also non flammable and non melting?
Or perhaps I can just duct tape over the outside of the tub on only the problem feeders? Will duct tape on the back outside of the tub have problems if that close to the heat tape? Like will the adhesive come loose from the heat?
