i'm also not trying to be a dick here, but they're called testers for a reason imo..
many breeders will give out thousands of beans as testers.. they could be testing one of many things, germ rates, how they handle different environments, intersex traits, etc, etc.. being that most growers can only grow x amount of plants at one time, testers are a vital part of a strain project..
often times testers will report back with say intersex traits, bad germ rates, w/e, and the entire project will get scrapped and or put on a back burner.. this is the role the person testing said beans plays.. if you're testing gear, ime, it's not best to run a test crop and nothing else, unless you don't mind your time and effort all being for naught, except the information to help said breeder..
to slam a breeder for test beans though, idk, that's why they're called testers and they're not for sale yet imvho..
