how long do you think? Flowering

I have 1 cheisel plant, and one sage and sour!
first off whick one would have the wider leaves and which one would have the thinner leaves?
second how long do you think i should keep them into flowering mode? im waiting untill they are about 2 feet tall which should be at the end of november
third, how much do you think ill get from each plant?

Sativa's have thinner leaves, Indica's have wider leaves. Look up your strains on Seedfinder, they usually have broad guidelines as to how long to flower. Yields are almost impossible to estimate, especially without pics late into flowering. I think you should do a whole lot of reading and researching on everything cannabis. Get a good working knowledge, then when you get stuck on something come to this forum and ask questions. A good general background is a must before going into a grow. Otherwise you wil get in over your head very quickly. GL.

As far as your yield. To many factors, your guess is as good as ours.

Good Luck
