OH, I think I came across your website a while back or maybe the youtube video because I did in fact see this design many moons ago! I actually have it on my list of things to build once I get my farm!!! I could have sworn I asked you (or maybe elsewhere) if I could use Polyurethane to coat the inside. I was planning to try it anyway. Great to have you here bsfman!

BTW, I went this morning to add some BSF to the bucket of rabbit poop I filled yesterday. Well I had the lid on it, and when I opened it I found hundreds of larger larva on the top. Most looked dead. I had some stuff in the bottom of the bucket before for who knows how long. This evening just before sunset I opened it again because I was going to take the dead ones and feed them to the Tilapia, but now there were 3-4 times as many and they were alive! I'm not sure if the others were dead (it was really hot), but who knows... Hopefully they enjoy the treats the rabbits made for them!
