I am growing Cindy 99. My clones under flowering are fairly short and bushy, but they were flowered immediatly, no veg at all once they were transplanted into dirt (1 gallons). However my mothers grow pretty tall. The branches seem to like to go out at 90 degree angles, might just be a specific phenotype or something on this plant. They regenerate quickly, faster then my Trainwreck.

Are you sure its C99? The smell is very distinct.
