When the plant starts to flower (throws pistils) is usually the start of flower no??
Breeders usually use the day they flip as day 1.
The start of flower isn’t what’s important. The end of flower/harvest is though. Don’t count the breeder days. Don’t use pistils as a indication they are ready. Buy a cheap microscope and check the trichomes.
I always love watching this debate. Been about 10 months since this was on the front page. As a personal medical grower I just don’t count. The plants can’t count, why should I. I have a journal so I can get a time line. Grow the plant, flip the plant, the plant will show you when it’s done. No counting needed.
