I plan on this summer breeding night crawlers since i'm sick of always having to buy worms for my three salamanders. I was wondering what is the best way to breed night crawlers or earth worms? Would a basement be cool enough for either of those? Would a 27 gallon tub be big enough and deep enough? Is topsoil and compost manure good substrate for the worms? What can i feed them that will keep smells to a minimum, my mother in law has forbidden the them to stink, even if it's in a stinky basement?
