What is the fastest you can grow a single plant? No specific yeild, just the shortest you could grow a plant that'd produce buds.
fast flowering strains finish in 45-50 days. If you go 12/12 from seed, you won't see flowers til 3 weeks or so, so that means 65-70 days from seed. From clone I bet you could go 12/12 from the time it was cut and finish it in 50-55 days, but it would have shit for yield without a root system either way. edit- I have no experience with auto's, so I have no idea how long they take.
