I have three bathtubs (cost was right, all given to me!) I have one for a rain collection device which also serves as a place for my dogs to jump in and cool off in hot weather and tree toads to breed in. I put wire over the other two so no animal will fall in and get stuck, but my intention is to use them for earthworm breeding beds, which I read somewhere on the internet (don't remember where) was a good use for them as long as you keep a sponge or filter in the drain hole and tip them slightly so extra liquid from the worms can drain out -- a super liquid fertilizer for the garden!(posted 9628 days ago)Just a thought so the tubs can be used by Hendo and others who don't use them for waterers any more!
