    Default Rules For Mounting

    Since I recently built my greenhouse earlier this summer I have gotten on this kick of monting a lot of stuff. In my mind, if it's an ephiyte, it can grow mounted. I can save a lot of room by mounting stuff plus I think it looks way better than growing in pots. Anyway, somebody please either stop me or give me the green light on what I am doing. Am I right in my thinking that almost any ephyite will do good mounted? I know it will depend on my care but assuming I can keep them adequetly watered, why not? Also, there is the "general" rule to repot during active growth, does the same rule hold true for converting orchids from pots to mounts? I suspect that I will find that most of the non-resting orchids in the greenhouse will be growing almost year round so it won't matter. Thanks for any help.

    ok...here ya go.

    while studying s/h, i believe that i read that air roots (those that are mounted) act in a different way than ground roots. so if you want to mount stuff, wait for new root tips. that being said, a greenhouse environment is warm and moist, which is conducive to root growth, so maybe it doesnt matter if theyre growing new roots or not.

    not very helpful, right?
    maybe you could do a couple of test orchids?

    Travis, f you mount them during active root growth, they'll attach faster. And yes, if it's an epiphyte, provided you keep up with watering, etc., it can be mounted. The only time you'll run into a problem is if, like kewpie mentioned, you unpot and mount them when it's not the active growing season and the plant doesn't already have aerial roots. Roots that have grown submerged in medium and adapted to those conditions will tend to die when exposed to constant air, and the reverse is true as well: roots that have established themselves aerially will tend to die when submerged in medium. So the best time to mount a plant that will disrupt it as little as possible is when roots are actively growing and can acclimate themselves to their new situation. I don't know what your latitude is, but even in the greenhouse here, there's still "seasonality." You could heat to 75 in the winter to try and mimic the tropics, but you'd have to compensate for winter's lower light levels too.

    Glad you got your greenhouse built. Snap a few pics when you get a chance!

    Here's pics of the GH, I didn't see an appropriate section in the photo gallery but feel free to move them if nessecary lja.

    Here is the site before, it is an existing concrete patio covered by a polycarb roof structure:

    Here is what I did with it:

    <img src="http://img.photobucket.com/albums/v195/Travis_in_OR/Greenhouse/after.jpg">
    I have since added shade cloth and a lot more plants

    Some mounts:

    A ceiling fan and exhaust fan:

    You can see why I want to maximize the mounts. Bench space is getting full already. This is my 5 year plan. In 5 years I hope to buy/build a nice, bigger, freestanding GH.

    Thanks,
    Travis

    Yee Ha! Well done! The structure and the plant mounts look great. If there's a convenient way to do it, you might consider hinging a panel section between the two joists closest to the existing house structure, and covering it with screen. That way, when your fan at the peak kicks on to exhaust hot air, you can get cooler air flowing through without having to keep the door open.

    Good work!

    That still looks so clean It is rather small and might cause problems with overheating and cooling too fast, hope you get a bigger gh before long. But then what do I know about greenhouse growing in Oregon.
    One question: what is that black and blue thing on top near the house? Just curious.
