I just went back to check how old the plants above are. Wednesday they will be 77 days old. Two have already been harvested. The smaller one above will probably be harvested this weekend putting it at 80 days total. I have 1 fast buds left after that but it looks to have another 20 days or so.
So far fast buds strains are the closest I've grown as far as the breeders timetable. Their genetics also seem to be pretty solid. I have not been disappointed in any of the plants I've grown from them. Saying that I have not found them to be the biggest producers compared to some others. However their descriptors on taste, aroma, growing, and type of high is right on cue. So overall if you want to be able to grow plants that do not disappoint in the quality department they are a good choice.
