Waterproof mat for Akerbar large?
Well, I thought I'd sufficiently sealed my Akerbar (25.25" size) with silicone sealant to keep it from leaking between the frame and the bottom tray. Turns out, I did not! Or perhaps the sealant separated a bit.
Regardless, I need a waterproof mat that I can set it on so that if any more water leaks out of the bottom, it won't spill all over my dining table (where the greenhouse lives) and the floor beneath.
There are tons of options on Amazon for products like this, with a raised edge to keep spills in place. Most seem to be either for use as pet feeding mats, or undersink mats. They're great, except none of them have suitable proportions - I'd like one that's just a bit larger than the footprint of the greenhouse, but most of the ones I'm finding that are long enough are way too deep.
The best options I've found thus far are rubber boot trays. Those do come in the right proportions, more or less... but they're not very attractive, and I eat at this table. Anyone have eyes on a silicone mat with a raised edge that's a good size for this particular greenhouse? Thanks in advance!
