You can start from seed in 12/12 with any variety, but some do better than others. In my experience some seem to lag behind, and take just as long as if you had vegged it, but others take off like any a vegged plant right into a stretch, and flower. If you want to do a perpetual harvest grow on 12/12 start double the seeds as usual, and weed out the weak ones.
scrumby Reviewed by scrumby on . Quick Question: Youngest Flowering start? Hey How young can I start the flowering process? Currently plants are on 18/6 under CFLs, roughly 4 days since they popped up from the soil. A guide I've been kind of following starts on day 16, but I'm on a time crunch so is 14 days too soon? What is the minimum? Thanks Rating: 5
