How many clone cuttings can you take of one mother plant a month?

I am new to growing, I am trying to figure out how many clone cuttings can you take of 14 mother plants a month?

I think three to four clones every two weeks per plant is a good starting point, so say for 14 plants you're probably averaging at 100 clones a month in my opinion.
That's quite a lot of plants, if your new to growing you're probably are taking on too much with that many, and you won't be able to smoke them all that quickly.

I had a couple mother plants like a year ago I probably could have taken 100 clones off each one.

Depends on how big they are and how healthy they are. But to answer your question... hundreds.

6-8 every two weeks or so depends on size the longer you veg it the more shoots you will have to choose from dont cut more than 25% and let heal for two weeks and repeat

From a plant in a 5 gallon pot I'd say 60-200

I used to get a tray every two weeks from my normal sized moms in 5g's without even noticing it. Took about 4 or 5 month to get them to that size on average.
