You can do it! I don't know where you are in Texas and if humidity's an issue for you, but Id consider starting them in a 'grow house/tray', or an old aquarium, something like that where you can maintain a higher humidity while the get their bearings so to speak. There will probably be a mix of sizes in the flask, from some almost as big as seedlings you may have bought individually to some that are just past (or even still) protocorms. I'd put them in compots with similar sized siblings. The smallest ones will probably die off; don't be sad, they would have anyhow. They should be good growers, the only thing I'd worry about is a quick spreading fungus or rot damp off which can wipe out a compot in a day. Just keep an eye on them. I agree, once you get them going you should have no problem selling off the extras, I'd buy one of those! They should be stunning in, oh, four or five years...
