I suspect that neither CCI nor SF are all that thrilled that F-rats work just fine as substrate for FungiMonkey's 4-cubic-decimeter self-contained Hydroponic Mushroom Flat (Fresh and delicious, grow them yourself!) and in fact slightly better than the official stuff due to limitations in working around patented/successfully-kept-secret production processes. But, since spore paste is only sold as part of a kit which includes FM's version of growth medium and using a case of F-rats to replace it means they bought a case of F-rats, combining the two products remains a bit of food service tribal lore that the companies put up with.
