47 days start to finish. then 30 days of curing. havent harvetsed yet, going to try the 24hrs of dark on these before i cut them. i posted some pic check them out. Yes the yeild is not alot but when you do 40 yeild shoud be great. i dont sell only for my use so, it should last a long time. sertain strains will yeild alittle more than others so thats a plus. thye veg time is only 10 days then it flower time with the light not changing. no you can not clone life span is not long enough besides you cut a branch you lose bud. if you started 10 and contenued for a month, starting each week soon you would be harvesting every week till you stoped starting seeds.
