ant-fungal property, and maintained all the other good characteristics of perlite/vermiculite, it probably wouldn't be worth the premium to me........I've always had a VERY good hatch ratio when using vermiculite. But I do know, that MANY people DO NOT mix the two correctly, and is a huge determining factor in hatching success!!....I've never had any fungus issues to speak of either, as too much moisture without enough ventilation will certainly make fungus more likely(as well as swelling the egg and drowning the embryo).......then you have the other side of the spectrum, with eggs being too dry and shriveling up!!....but if it is like the other guy said,...all premixed with correct moisture content, just dump & go, I suppose it might be better for some,......also, for people that incubate on a very large scale, if you didn't have to maintain it at all, I could see a definite advantage!!,.....I guess we'll all find out soon enough if it is a great performer!!...........................Doug
