My mother plants are doing just fine. Still the size of a bonzai and I have encountered no problems with them.
Sometimes I have forgot to water them 2-3 days but they bounce right back in 6-8 hours again.

I would say bonzai is the way to go for a small to medium op since you easy can keep 2-3 moms on a square foot under a 125W LE and take around 20-25 clones a month from them.
