I'm up in the north and I have seedlings that are going to be four years old this coming summer. My estimation would be at least 6-7 years before I register them and have enough to sell. Here it take 2 years before I see bloom on my seedlings. I don't use a greenhouse or lights to grow my seeds. I just plant them in beer cups and put them in a south facing window.
I clean my seedling bed out after the second year of bloom. Most of the plants are just blooming for the first time. Yes I know this is brutal , but I don't have much room and I make lots of seeds every year , so I need to keep the rotation going.
