Damn, got a non- auto instead of an auto for your fitst grow...that sucks.....typically, autos will finish wihtin a few days of a breeders rec...but if it doesn't auto, finishing time will be questionable also. You'll just have to watch the obvious things for a photo .......receding hairs, swelling of pods, trics etc.....
I do mostly autos although I throw a photo in some also.....I have my grows set up perpetually with a staggered harvest which is easy to keep on schedule as autos do finish pretty much on time.....
As secret one said, getcha some stable autos to enjoy the fruits of what autos have to offer. The allow me to keep quite a selection of meds to chose from year round...
