How many mommas do I need?

I want to be able to have a crop every two months.
If i'm planning on growing 8 plants at a time how many mommas do I need?

Thanks,
Bill

Idunno two?

I would think atleast two, maybe as many as four.

just need one sold mom that you can clone from. just pick your best female (which does not have to mean the tallest)

You can get away with one good mother, if done right some people can take as muc has 20 clones from a mother.. Also say you want 8 every 2 months get 9 and grow your self a new mother every 2 months, then when the new mother is rip, get rid of the old, so she is always fresh, infinite clones if done right..
