    I have 7 or 8 Vandas, 6 are seedlings bought over a year ago from R.F. Orchids. The oldest one, from 2012, has bloomed 3 times for me. The 2nd time, the flowers lasted for over 4 months....indoors.
    I live in North Carolina where the humidity is high in the summer, where they are kept. Winter time it's very dry because of indoor heating. Late fall they come indoors until May. The artificial lighting is 4 4 ft. T5 fluorescent bulbs and one 150W HPS. The T5's are kept on for 12 hrs./day, the HPS about 1.5 hrs. What works for the Vandas and Oncidiums is 2 humidifiers. They're used during the day and turned down a bit at night. I also mist the roots in the AM before going to work. The humidity is usually 55-65%. If it's raining hard, I can sometimes turn them off completely.
    I also have a Lou Sneary Bluebird from Chadwick and Sons. It's mounted on tree bark and bloomed 6 weeks after bringing it home. Another vanda that has adorable blue/lavender flowers.
    Yes, a lot of work but they're worth it! I can't wait for Pachara Delight to get bigger and then bloom. Vandas are gorgeous in full bloom. Good luck!

    Hi Puppies2 and thanks for the detailed response. It's appreciated! I like very much what your doing for your Vandas. Ive got about 25 or so Vandaceous type orchids and though I have the 44 foot T5 fluorescent bulbs I don't have the 150 W. HPS. I have three good humidifiers. My humidity on a windy, cold day like today is 50% to 60% depending on how high the wind gusts get. Winds here can go on for weeks at a time, especially in March and April you can count on it happening every year. Winter is more intermittent depending on the cold fronts coming in. 25 to 60 mile per hour gusts of wind are common in the High Desert. We had a hours lull in the wind speed in the afternoon and after heavy misting the humidity jumped up to as high as 76%. Once the winds picked up again it was back down to 50% to 60%. The winds and heat just blow the humidity down. A indirect Misting system should help or its certainly worth a try. The summer is our rainy season and I have a large capacity evaporative cooler for a 8 by 14 foot greenhouse, so humidity or high temperatures are not a issue May to at least mid November. For those in high desert cllimate's this gives you all an idea of what has helped so far. I've had 8 Vanda types bloom so far in 2013 with one more in spike as we speak. This has been a slow Vanda flowering year. I hope for more blooms next year. AL

    We get wind storms in Denver during the winter some times. In fact, I dislike the wind storms more than anything except maybe hail. I have had debris hit the side of my car going to work in a wind storm and dent me. Trucks get blown over regularly here in Colorado. Especially on the north/south routes.

    I don't know if I qualify to respond since I live in south Florida, but I will anyway, lol, I've found I had to keep concrete away the vandas growing on the edge of my shade "house" , once I replaced it with lava rock on the ground the roots and leaves were visibly better, I believe the concrete gave off a baking heat, I mention this Al because you noticed a difference of yours growing over plants. One of the best things I ever did was get a patio mist system at a box store and set it up for the vandas, they loved it, my dens liked it , but my catts hated it, and anything mounted took off like crazy.

    I think Vandas are easy if you grow them in tall vases . Just fill the vase up for 30 min every week then drain the water .. i turn the plant up side down until water stops.. I used tomato fertilizer this year and they are all in bloom

    @ Timur. This is something uniquely Dutch. You are the second person from the Netherlands to highlight this method in OTF. I think I'll try this with one of my vandas.

    You always qualify to respond Ed. I value your opinion. Have you ever noticed that most orchids lovers are intelligent people? This of course includes you Ed. The misting system idea sounds like the best option in my greenhouse and though I have very minimal space I think i can make it work. Thanks for giving me your first hand experience. AL

    I think vase culture with Vandas can work well, especially in the home. In my green house though I don't know how I'd capture enough light unless I hang the Vanda high towards more sun. Do you keep your Vanda's in very bright indirect light Timur? Like window exposure or skylights? AL

    The vase system looks really interesting. I wonder if it would counteract our dryness and help them to thrive. Now I need to repeat after myself, I do NOT have room for more large orchids, I do NOT have room. Probably a losing battle.
