    Default Tolumnia placement?

    I'm wondering what I should do with my Tolumnias. I have two of the little things and right now they're in an Eastern window. I'm wondering if I should put them outside with my Catts, though? I've read these things like lots of light, but they're one of those orchids that have pretty contradictory information online. I'm a bit intimidated by their small size...I'm afraid if I put them out to hang out with the Catts they'll fry. I'm assuming they tougher than their size gives them credit for, though. Any experience and suggestions with these? (They're also growing in tiny pots with no media)

    I'd stick with Oncidium lighting.

    i would definitely move them outdoors. i grow a few outdoors all year round, but i have bloomed them in a south facing window. they like high light, think vandas and cattleya. even a little early AM sun... like as the sun is rising, or maybe as the sun is setting, but no direct sun during the day. they need to be acclimated slowly and once settled don't like to be moved around. i have not had the best luck with them in the little clay pots, but better luck with small 3" tree fern pots here, because it is so dry. in a more humid place it might be different. daily misting!! first thing every morning if outdoors.

    In nature, they originate in tiny twigs of sparse shrubs on the windward side of Caribbean islands - Hot, scorching, with frequent showers and drying winds.

    For me, they do best when hung up with the vandas, and I agree with coeruleo - frequent watering.

    I just upgraded the placement of 2 of my Tols that are mounted together on one large cork wood slab. Moved them outside and gave them sun exposure. Both seemed stunted in their previous pottings, so I thought I would try them mounted. And see how they do.
    I know I will have to water it morning and night while outside.

    Raybark .. I water my tolumnias twcie a week .. put them at balcony, sun facing north (too bad my apartment is such) but at the end, I found that few stems were rotten due to too much water ... pot wise with proper drainage and medium with added small styrofoam.
    What do you think really gone wrong?

    Tolumnias, in my experience, need a LOT of air flow to the roots. The only time I've been successful with them in pot culture is in tiny clay "thumb" pots (they're just big enough to stick your thumb into them), and no medium whatsoever.

    They'll likely never do well with only north-facing light.

    Kind of off topic, but I think Tolumnias are one of the few orchids that are just as fascniating and aesthetically pleasing as a plant out of bloom than with flowers. They're like succulents!

    I currently have mine in thumb clay pots with no medium in an Eastern window that recieves direct sun for about 5 hours in the morning. I tend to water almost every day, as they dry out quite quickly.

    I've found that due to the thin nature of the leaves of the plant they are harder to burn than wide-leaved catts.
