I know this is a old thread and I didnt read thru all this one yet, but I had to add, I ran the G13 labs c99, not sure why, prob user error but the plant from seed was like hay and I feel bad for posting it was crappy, I had cloned the plant before flower and I am glad I did, all the clones were clasic c99 smell, taste, it was a grapefruit x Pineapple pheno type taste smell, I got fox tail buds longer than my arm on the clones even. Lots of crystals and fast flower and fast veg, 52 days flower, same as classic C99. Yes I am prob one of the top Brothers Grimm C99 fans (and have grown 1,000's of their c99 back in the day, still run them now but I Am not going to run G13 labs version again. The female seeds version is great also and the Mosca BX-1 version I run now is sweet too. There are a couple others that Use real brothers grimm phenos also I hear but the Doctor green thumb is high priced but then again he has S1's. Prob best you could get. But others are close.
