How many clones???

I have 3 plants all different strains from feminized seeds, all 6 or 7 nodes and 15-18 inches tall.
My question is how many clones can I take from each plant? in addition how long should I wait after taking the clones to switch these plants to flower?

Any help would be greatly appreciated!!!

Pics would help.

you can take clones like 6 off of each plant

dont take too much it does go into shock but you can take like said above about 6-10 and wait like 1 week or 2...like when the plant has been shown its grown past that for a few days

Sweet, I think I'm gonna go 4 from each. Thanks for the quick response guys!!
