How many mums to keep

right im setting up a grow and i need to be able to take 30 ish clones at a time how many momma plants u think i should keep?

3 should be fine. Mums the word! =)

i can only manage 20 uniform clones off of one little moma,so atleast 2

thx chaps was thinkin 2-3

I think 2 mothers but each grafted to produce 3 strains, making 6 strains in all.
But then again, that would be for personal use and I would never need 30+ clones of the same strain.
