How many mother's for 60 clones?

Hi there, I am going to use a 2 60-site aeroponics setup. For a continuous run I will need 60 clones every month. How many mother's will I need for thick SoG tall type clones? Btw there will be no veggie time, it will go strt into flowering after they have rooted to keep them short. 12 mothers? More? please help thanks.

There is a guy on this site that uses 5-6 mothers to get 400 clones every 8 weeks.

3 HEALTHY mothers will be more than enough for you

cheers

depending on the mother size, i can get a good 300 clones out of 2 mothers that are about 4ft tall.

how in the world do you get 300 clones off plants that are 4 feet tall thats nuts
