I grow on a south-west windowsill, with slight shading (double layer sheer curtain). I have 2 fans running all the time and supplement humidity with my humidifiers. I do not greenhouse grow. Do you think the last bit of information applies to my conditions?
    If you grow indoors, you should keep an eye on the medium and when it is dried out, water by running water through the pot. Cattleya orchids need to dry completely before being watered again. They do best in 40 – 65 % relative humidity.

    Great Orchid, I have one which has never bloomed and it has reached a decent size. How much light does it get Bruce?

    Hey Eric, This one needs pretty high light. I grow it hanging in the top of my greenhouse with the vandas. The foliage should be very light green/yellow green for it to bloom. If yours is dark green, it needs more light. Likely that is the case if you are growing it indoors. I read that you have a balcony in your new place, but it is winter. Maybe there is a way to add some supplemental light until it is warm enough to move outdoors or into a brighter, filtered light. Good luck!

    Cheers,
    BD

    It is a good old one this. Registered in 1968 by Rod McL - are they still in business, I wonder ? Has been meristemmed many times I reckon - quite freely available on this side of the Atlantic - or at least from several EU nurseries ( I wonder of I am going to need CITES to bring back plants from Paris - European Orchid Conference next year , after Brexit ?) What a roller coaster we are having in UK at the moment - has quite displaced your presidential election off the newspapers !

    Thanks for your advise Bruce, I will give it the brightest spot and hope for the better. I leave my orchids outside even it's winter here as the minimum temperature is only around 50F (10 degree celsius).

    I mounted mine! Very stressful - but it had no roots. It is a mature plant. Very dark green leaves. (no-no) ! But I grow on the windowsill. Tons of humidity and air circulation. My mini greenhouse. I have been cautioned regarding too much direct sunlight, so I am exposing it gradually. In fact, all my cattelyas are deep, dark green! Care to comment??? Please???

    Likely your plants are still healthy being deep, dark green, but even more likely is that they will not bloom for you. The number one reason orchids do not rebloom is due to insuffencent light. Do not put them in direct light as that will burn the leaves, but they need to be slowly eased into brighter, filtered light so that they get to a nice yellow green color. Good luck, Marcella!

    cheers,
