    Personally, I don't like leaving the agar on. Maybe it's just (again) the way I learned, but agar is, for all intents and purposes, mostly sugar, and I think that leaving it on just adds to the risk of mold and fungus. On the other hand, Antec Labs swears by the "agar-on" method, so maybe, like Ki said, you can try both ways and see which works best for you. One little side note: if you do go the "no-agar" route, when you're rinsing the seedlings in Physan (or whatever you're using after you deflask), it's really easy to get tempted into trying to remove every last little bit of agar from the roots. Don't do it! You'll end up pulling roots off along with that last agar blob, and while the plants will eventually grow more roots, you'll just be increasing their stress.

    Here are some very well-written instructions from Antec concerning deflasking and compotting using the "agar-on" method. It's well worth the read if that's the route you decide to take. They, along with many other well-known paph growers, don't use anti-fungal at all to rinse their seedlings when compotting. There's a symbiotic relationship that paphs have with certain beneficial, "sugar-producing" fungi which grows the seedlings stronger, faster: a relationship that would be destroyed if they were rinsed in fungicide. But whether that applies to other genera as well, I'm not sure....

    Just checked it... good info there. I really like the jig and sphag method he shows. Here's the link: Troy Meyers

    Ki, is that how you compotted yours?

    nah - too lazy to do the jig thing.... but the phals are easy enough to handle that I can mimick it. I use the same idea for non-orchid seedlings - start at one side and keep packing.... loosely. Popsicle sticks (and chopsticks) can come in handy too.

    well, i still havent done anything yet, so any and all comments are welcome. it seems like people (specifically lja, ki, and persistence) generally rinse their agar. i think that i will take kis advice and do a 1/2 and 1/2...see how it all works out. i have definitely been poring over the info on both troys and antecs sites, as well as home orchid growing.
    as a side note, i wonder if the agar-on business is only good for paphs ....the guy who runs slipperorchid.com has this flash tutorial that shows him compotting with the agar attached.

    i think i am too, even though it looks like a really cool idea. im not planning to compot in all sphag, anyway. ive got a mix of small chc, perlite, small diatomite, charcoal, and chopped up sphag that im planning on using. i will, of course, be soaking all of said ingredients in a dilute physan solution. the plants involved are some alba (aurea, if you want to get technical) psychopsis and some neofinetias. does anyone -- for whatever reason -- have any objections? cuz i really really want to know. dont want to be a baby killer.

    Just an update on my end. I did some fungiciding today and found nice globs of mould - the little bits of agar that I didn't catch. Pretty freaky healthy cultures, lol.

    hmmm....your mold is making me rethink the agar thing.

    how often are you treating your plantlets with fungicide, ki? only when you see a problem? or are you physaning them weekly?

    So I got the flask on Aug 26 and deflasked that night - that's 8 days ago. When I deflasked, the plants, potting media, pots and tray all got washed down/soaked/drowned/rinsed with/in physan. About 3 days ago, I noticed some moldy things going on - mostly the globs of agar and some damaged leaf tips - but was too busy to do anything about it. I only got around to doing the first post-deflasking treatment this morning. I actually used regular fungicide (Cleary's at a touch weaker strength) because I don't trust Physan to do much more than help inhibit fungal problems. Dunno if Clearys is ok on flasklings - guess I'll find out. My choices were physan, clearys or rose spray, so....

    sorry about your fungus.

    is the rose spray daconil? cuz i read in another forum that daconil works to stave off damp-off and is safe for the little guys.

    i cant wait until ive got my plants in compots. ill be leaving town tomorrow, and im coming back on wednesday. guess what im going to be doing the first thing i get back!
