They suck because they dont care about you they care about your money all there good genetics left when shanti an neville did. They would rather spend their money on coloring seedd than getting better genetics
lol, i like this answer.. but the real answer is pretty much that the king of cannabis, mr arjan, isn't a breeder, never was, never will be... greenhouse really made their name back in the 90s when they had ace breeder shanti, also part owner of the co at the time, breeding all of their gear..
things went south, and shanti left and sold arjan his part of the co, and then took his mother stock and went over to mr nice seeds with neville shoenbaucher or w/e his last name is..
mr nice now has all of the genetics for the cannabis cup winning strains such as white widow, now called black wiow, and a few others that gave greenhouse the name they have...
arjan is more of a salesman, and a damn good one at that, but far far from the breeder who tries to sound like he is..
they are more concerned with dropping near gear every other month then quality.. it can take years to create and stabilize one strain, yet ghsc manage to drop more new gear then pretty much any other co. out there.. that right there should send up big red flags.. it takes time to create quality cannabis strains..
look at say simon and serious seeds.. they have maybe 5 or 6 strains out.. but they are all top notch, quality that has been worked and stabilized very well.. they are more concerned over putting out a few very good strains instead of tons of bunk.
yah, greenhouse may have won the cc a few times in the last few years, but don't think that amounts to a hill of beans about the quality of their product.. they may have had on distinct pheno of super lemon haze that was super bomb.. the thing is, you might have to crack 100 beans to find that one pheno, and the rest of them are no where near as good.. that's not such a great image imo.
there are much better breeders and seed co.s out there.. many of them are small time, but again, they concern themselves with a couple of strains that are straight up fire, work those lines to create stable hybrids, then release them to the public..
