How long can clones survive in an Ez-Cloner?

Does anyone know how long it's possible to keep clones alive in an easy cloner?

I'd really like to be able to take a bunch of cuttings just before I induce flowering and then have them ready to go after the first group is harvested... is it possible to keep clones alive in an easy cloner for 2+ months?

If this won't work, does anyone else have any good suggestions on how to achieve perpetual clones like this other than keeping a permanent mother plant?

If not, does anyone have suggestions on a good/simple mother plant setup?

I would like to hear what the pros say about this. I just got an ezclone given to me and I'm not sure what all I can do with the bugger. I put my two month old soil clones in mine yesterday, don't see why it won't work unless the roots get to big for the sprayers to be effective....
