i will be building a rack system to house my snakes.. it will only be 5 32 qt sterilite tubs but i was wondering about materials to use... ill be using flexwatt and a helix thermostat to control the temps but should i use 1/2 plywood or melamine... cost is sort of a concern to me and also care.... can i just cut and use the melamine to do i have to seal it like i would the plywood? cause if a lot more work goes into the plywood then ill prolly just end up using the melamine..... anyways what do you guys think would be best to use?
