I've already sampled all of the five plants 2 weeks ago, plus I've grown C99 for 5 years now. I can tell you you can't go wrong with this strain. The high is excellent; 3 tokes and you're buzzing. The smoke is smooth - no long coughing episodes. C99 also clones very well. The only negative with this strain is its susceptibility to mold. I lost about 10% due to this. BTW I'm using the original C99 seeds crossbred to produce F1's. Oh, one last thing : The smell is virtually zero from C99 compared to other strains. Big bonus. I've walked past drug dogs with several joints on my person and the critters just looked bored.
