    Does anybody have any experience deflasking this genus?
    I acquired a flask of Microcoelia obovata and the seller suggested to keep them on a bed of spanish moss and keep them constantly moist. My understanding is that this species is from rather dry environment and experiences prolonged dryness in nature. Should I let the newly deflasked seedlings to dry out or still keep them constantly moist at 90% humidity?
    Any input is much appreciated, thank you!

    I use a large terrarium with 90-95% relative humidity on my newly deflasked seedlings but I've never deflasked anything leafless.

    My only personal experience was deflasking Microcoelia exilis. I mounted them on hardwood with no moisture retentive material and had very little loss. They dry very quickly.

    For Chiloschista I lay them in a try with landscape fabric underneath them. They do not root on to the landscape fabric, but do develop until ready to mount. You could put a thin layer of spanish moss on top.

    I've been told that for Dendrophylax sallei it works well to lay them out on top of spanish moss.

    Thank you, Marni.
    Did you mount even the smallest seedlings of M. exilis right out of flask as well? What humidity did you maintain around your mounted plants?

    I de-flasked M. gilpinae last year onto a bed of Spanish Moss (Tillandsia usneoides) in a largely open nursery flat. I kept it watered often and found the Tillandsia dried quickly but maintained a humid environment that kept the Microcoelia roots active.

    There is a local nursery that does this with all or most of the leafless species they de-flask out in a shadehouse, and they have very good success.

    Thank you, goods.
    Did you keep newly deflasked seedlings shady?

    By the way, if anybody wants to trade Microcoelia seedlings, I'd be down for that as soon as mine are established.

    Yes, I did mount all of them immediately. The humidity in that area is about 75 to 80%. If I had known at that time about laying them in a tray I probably would have thought differently about it.

    I was growing them under lights, so it's hard to translate that to under sun conditions. I would say they were getting fairly high amounts of light, though.
