I'm working on getting the materials I need to complete the hybrid acrylic/natural design. The design calls for an optional wooden floor. Laser cut hydration vents in the floor allow moisture through as ambient humidity. A thin plastic film sits above the hydration reservoir just beneath the floor, keeping the wood from becoming saturated or getting in direct contact with the sponge/water.
Anyways, it is likely that thinner material would work best, as there will be less distance for the humid air to travel from the sponge section, to the nest area where the ants are being kept.
Any moisture on the inside of the nest can soak into the top of the wood, but the bottom of the wood floor is protected by the film, with only holes and slots cut to match the vents in the wooden floor.
Does anyone have any experience with 1/16" hardwood? It's either that or 1/8" plywood with hardwood veneer. I'm wondering whether the glue that holds together the plywood may be less durable in a semi-moist environment. Likewise, I'm wondering if 1/16" will be too thin and prone to warping. Maybe I should get both and see?
Here is the list of hardwoods I think would be most suitable, simply from the perspective of color contrast with respect to housing ants. Time will tell if ants will be able to find a way to chew through these wooden floors—not that they'd get anywhere with the PETG film underneath. But that's not a concern right now, as much as the ability to work with the thinner, 1/16" hardwood material over the 1/8" plywood varieties.
