how many moms do I need?

I'm considering a sog setup, and plan on 24p/ month perpetual. How many mother plants do I need to supply 24 clones a month? Moms are kept in 7gal. Soil containers under 400w. MH.
Would 3 moms be good? (10clones each, and pick best 24).

sum1 i know just took 20 from 2 plants so yeh completely cool

3 should be more than enough...if you want 24 then its an excellent idea to take more than the required amt( even 12 from each) so that you get the best of the batch...just make sure you know that they are 100 % female before taking any cuttings from the mom's... just in case one is a male/hermie...wouldn't want more of them!
