We bought a horse tank and wanted to use that for a worm bin. We have drilled holes in the bottom and built a wooden top. We have it placed on the east side of our barn but upon checking it noticed it was very warm inside even as I dug down into the casting which fills about 20 inches from the bottom of the bin. We've had a wooden bin for about 10 years. Wondering if this horse trough will work and how to keep it cooler? Thanks
