Wrong....... these do get quite big (and tall). I remember Mosca mentioning that he tried to breed more weight into the strain, using a particularly heaving yielding parent. But, you are correct- normally, C99's don't yield much- which can be expected because they are (1) short flowering and (2) sativa. I know I averaged over 2.5 oz. per plant, which is high for my grow style. I will look for a pic or two over at THCFarmer of mine a ways back. The buds were all about the size of golf balls or slightly larger, thick and dense like a kush, but sweet (or citrus) smelling. I know my ONLY complaint was on the potency, but I let them go too long, around 58-60 days.
