I was just wondering how long has it taken your plants to get to about 1 foot, 3, 5, and hpw tall were they when you harvested?
I don't really know but im guessing a little over 1 month for each foot of growth. making a mini-greenhouse might help in the early stages but i'm not sure.
I find it takes about a month to reach one foot high, but about then they show their sex, and after I transplant the females into larger pots growth really takes off, and they are about 5 feet tall after 3 months (or they would be if I didn´t tie them down). I think the maximum height obtained is restricted by the pot size that I use.
