Hi, I'm going to be making some shelves to hold some small aquariums (think a long stand along the wall or a rack). I'm trying to decide on the material to use for the actual shelf the tanks will sit on I don't expect it to be continually wet, but I'm sure water will get on it from time to time, not to mention humidity.
For that reason, I know MDF is out.
Can I use the outdoor plywood they use for siding? Or do I need to spend the bucks for double sided MDO (
Medium Density Overlay) which is what they use for making outdoor signs?
I don't want the wood to warp or rot from getting wet.
One more question, is 1/2" thick enough, or should I go to 3/4"? The plywood will be supported around the edges, not all the tanks will go all the way to the support.
I've used planking in the past, but its just too expensive and comes in the wrong sizes. A 4x8 slab of Plywood will be perfect size wise.
