yea i been growing some bagseed for about 4 1/2 weeks now n i wanted to kno when i should start 12/12 schedule.
Usually anytime after they reach about 12 inches in height. I'm sure other people have before then but that is a good guideline to go by. If you aren't in that much of a hurry, wait until they are at least 18 inches or taller cause you"ll double your yield.
