I do bonsai moms and that would be nice. Im constantly having to trim them back. When you have limited room and try to keep a selection of strains its a pain.
I recently saw a thread on that topic. Looks really interesting and I may get brave and try it at some point.You could always try grafting multiple mother strains on to one root stock, never done it myself but I've seen others do it when they are worried about plant numbers.

I don't do bonsai mom's myself necessarily. What I do is keep them in a small pot, give them just enough food to keep them happy, trim and supercrop and reclone and start a new mom every few months.
I don't like to keep q mother plant for an excessive period of time because when I've done so for too long a gnat out break or root illness can happen and you end up losing the mother. I find it better to keep a rolling fresh one
I like the idea of having a fresh plant going, you avoid tons of those problems that come with neglected moms.
Oldtimers cloning thread (where ever it is) talked about putting a mother into a suspended state, not dead but in a bonsai state of suspended growth. Anyone know how to do this?
