i grew two strains of c99,and the ones i grew were ok but i wouldn't keep them.i know people will attack me on this,but i think it is hard to find what i call a keeper.for all the hype of this strain i was expecting more,but it never even came close to my grapefruit,but maybe it makes better cross,we will see,but i have had a lot better.but what do you expect for 7-8 week weed.
