How long until harvest for my outdoor Jack Herer (South Africa)

[jamjamdave]

Hi
This Jack Herer was planted into the soil 18 weeks ago in South Africa (we are coming to the end of our summer).

Any advice on how many weeks until I should harvest? (I've only grown our land race - Transkei Numba 1 - which flowers much later at 26-30 weeks).

Cannabis plants arent a ticking clock. There is no real "time" in the sense of how many days it takes to fully flower.

Watch the plant, when it shows you it's ready. Then it's time.
