Small Rack Construction

I'd go with 1/2" if 3/8" isn't available. With wood it is better to go thicker than to go thinner than what is recommended.

Also, I would advise coating everything in a layer of sealant to make it water/humidity proof, as well as heat resistant. Melamine is often used for constructing racks, if you can find the right dimensions. I, however, cannot.

Dont use the 1/4 inch stuff. I made one and some of the shelves warped and now the tubs dont fit.
Im making a new one with half inch so i can counter sink some heat rope into the shelf.
Here is a simple picture i drew in paintbrush just to give me an idea.

Im using the big apple heat rope thats 27 feet long and they have a new temp controll thats like 30 bucks.

Is sheathing plywood okay? I found that in 3/8". It seems like it may have chemicals. The pegboard looks a little more intruiging at this point, but would something like that warp? God, this is a pain!

It's thin but it's pressed and tempered, and formaldehide free.
