oooh, I've done these and I can honestly say that they are a lot easier to keep going than stuff from flask.
A lot of my Aussie Dendrobiums were bought as compots.
It's a good way to get loads of plants real quick. And doesn't usually take as long to get them to flowering size... maybe another 18 months... esp the ones with loads of Dend kingianum in them or the species itself.
actually add some of the coelogyne's. They are also fairly easy to grow, ie cristata or flacidda or maybe Bifrenaria harrisoniae (I have never yet killed any... woo hooo )
good luck with them.
