mother clones

When I create a mother clone, and I keep her in a continual vegetative stage, what's to stop her from growing to be 6 feet? I don't have a lot of space and would love to have a mother clone to take cuttings from, but at the same time not have to deal with the hassle of having this huge plant. How do I control her size?

Thanks for the help!

pruning, and also U can tie plants down, and train them to grow many weird ways....

You have to train them as soon as possible, you cant just take a 3 ft tall plant, and bend it in half.. It has to be a slow and as the plant grows.
It is possible though, you can have a shrub type grow if you can pull it off, and start early enough..

I havent myself done this, but Im sure its pretty much the only way..

Pot size will limit its growth. When it gets too big just make a new mom out of another clone.
