Greenhouse is almost exclusively renown for being the worst breeders aroud, they buy their cup wins, they dont earn them.
Well, I'm no fan of Greenhouse (and in fact I won't buy their ceeds at all), but I think this is a bit of an exaggeration. I think there probably are worse breeders out there, for one thing.
To me Greenhouse is more like the "McDonalds" of ceeds in the sense that they're the largest seller by volume irrespective of quality ("over ten billion served"). Although at least some of their genetics are questionable, and a portion undoubtedly mediocre, I'm sure out of their 20+ lines at least some of them are good. I realize this is damning by faint praise, but you probably could do worse.
Danny Danko of High Times magazine recently made a point of saying that Greenhouse has gotten a lot of flack over the particular issue of cup cheating (and it most certainly IS true that this particular house has been guilty of bribery in the past, effectively buying cups), but their last High Times Cannabis cup win was in blinded judging, so it must have meant something.
Without parsing his statement too much (ie was it REALLY blinded?, etc), in general I think its a bad idea to attribute too much meaning to contest wins.
Even stipulating legitimate judging, the criteria the judges use to pick winners probably aren't the same as what you should be using to grow strains at home. Specifically, the judges are only judging BUDS, they are NOT judging STRAINS, and this distinction is absolutely critical.
Specifically the judge are only looking at appearance, scent, flavor, potency, and high quality. They *can't* judge how hard it is to grow a strain, how hermie-prone it might be, how pest resistant, how stable/unstable the genetics, nor how good/bad yield is, and all these things matter a great deal to growers.
If you can only expect to see the cup entrant pheno in 1 out of 4 plants from a pack (or fewer. . .or NEVER), that's a big issue for growers that the judges will never be aware of. Likewise, if a particular "haze" is hermie prone, low yielding, and takes 18 weeks to finish, most growers aren't going to want to grow that in their homes, regardless of how good the buds turn out to be. If a particular plant is highly susceptible to bud rot or mites, etc, again, this is something of great interest to individual growers that isn't going to be reflected in a contest win (or loss).
Another issue unique to judging is that with 20+ entered strains to test in a relatively short time, the judges can't possibly really smoke and test all of them. Their first step is typically just to narrow the selection down by pure visual "bag appeal". This means that anything that wasn't trimmed right, cured right, or even just a strain that looks a bit "leafy" by nature might not stand a chance of winning, even if its great. Take the same 20 strains, and have them grown by different growers, trimmed and cured differently, and the outcome may well be different.
Almost by definition, judges are hardcore smokers, who've tried a lot of buds and probably smoke frequently. So they may have a sort of "critic bias", in that what appeals to them may not have the same appeal to the ordinary smoker. They're looking for something "different", even if most smokers may not be.
As another issue, I don't think High Times has ever actually publicized its cup entry criteria. Its certainly NOT "open entry", and I suspect its "invitation only" for their advertisers, which, assuming its true, presents its own set of issues. Of course, just because a given breeder's plant "A" wins a contest, that doesn't necessarily mean that their lines "B", "C", "D" and "E" are equally noteworthy.
The point is, the various cups are mostly intended to serve as publicity forums for their sponsors and their entrants. In that regard, they work extremely well. Even if the cups legitimately do select the best BUDS from a given set of entrants, that doesn't mean that the winning entrants are necessarily good choices for any individual grower. More simply, its a bad idea to pick a strain JUST because it won a cup, and by extension its a bad idea to choose a particular breeder just because they have won one (or more) cups.
That Greenhouse has won fifty-gazillion cups tells me mostly that they have figured out how to win cups. Whether or not being the most successful at what might be termed cup "gamesmanship" is the same thing as having "earned" the cups is debatable, but I don't think it tells me much at all about whether I do. . .or don't. . .want to grow their strains.
