    I have some seedlings just out flasked from our lab, and I would like to know which is the best way to grow them??

    Monted, potted?? If potted, with sphagnum, fine bark...??

    The way that I see Golden Gate Orchids do theirs is with sphagnum. I've been told by them, a perceived world expert of this species, that a high loss in the seedlings is to be expected.

    Some I have done mounted if they are large (2" or so), otherwise potted usually in moss in small platic pots and sometimes in fine bark. Tom of Golden Gate Orchids grows his seedlings in moss in plastic plug trays. Once established he moves them to moss in clay pots.

    I grow them in Kanuma , in plastic pots from the food of our bearded dragons ,because it´s perforated round the pot , but not below .
    Moist and cool every time without a cover .

    I had to look up Kanuma since I had never heard of it. Interesting.

    Giles, good luck with your efforts.

    I would go with anything that keeps them constantly damp/moist (not wet!!), good air movement and drainage, preferably something that doesn't break down. This is a good rule of thumb for all the oxyglossum species - So for example the medium that Andrea mentioned would be an excellent choice

    If you are working with seedlings keep them warmer, atleast during the day. - Infact i keep all my plants warm during the day, mature or seedling, and that's atleast at24C (75F). - They show increased vigor and growth.

    Just make sure they don't dry out whatever happens that is certain death.

    Actually, with constant good humidity, it is beneficial for mature plants if you let them dry out slightly/briefly.

    I grow some of mine(mature plants) on cork mount but I also have good luck with tree fern mix(1-2" long tree fern sticks, sponge rocks, small charcoals and moss) in basket. For seedlings, moss might be the common choice and I use moss for all newly deflasked seedlings(all genera in general), but like Marni said, the larger seedlings can be mounted.

    I love Kanuma, and use it extensively for my Nepenthes. I had wondered if it might work for this species... As I understand it, it is volcanic glass which has been whethered by weak organic acids.
