    Red face Keeping sunroom cool without airconditiong.

    Hello, I was wondering how the experts keep their orchids cool in the summer without removing the humidity. My sunroom gets hot with the shades down and windows open and ceiling fan on. Last year I lost several to a bacterial rot I believe was promoted by the heat. Can you help with some suggestions. I also have a small humidifier in the room. I keep the room closed off to the rest of the house that is airconditioned. I know that removes the humidity, but my phals need it. Thanks for your response.

    P. S. sorry for the misspelling.

    Joanna - I grow my orchids in a south-facing window, which can make it really hot right near the window, especially in the summer, and despite air conditioning. Humidity isn't the problem - that cools the plants down and you're right - the need that. What I've been told is the key to keeping the plants healthy is really good air movement. I have 4 small "muffin" fans directed in different ways, as well as a large fan pointed toward the ceiling. I also have 3 humidifiers going in order to keep the humidity around my orchids at between 60 and 70%. So, it may well be that you have all the right stuff - you just need more!

    I think air movement is the biggie. I agree with Maura...

    I have mine outside in a shadehouse and where I live summer temps average 95-105 the key for my is misting often to keep the leaf temp down. Air movement and humidity aren't an issue with winds averaging 15-25 mph and humidity averaging 50- 85%.

    Hi Joanna, I think very high humidity, lack of air movement and heat together were responsible for the bacterial rot, as only heat will reduce the humidity and cause scorching rather than bacterial problems. As others have pointed out, air movement is the key.

    Thank you all for your responses. I plan to add more fans in the room along with the ceiling fan. You are all so very helpful, Thank you!

    I grow my orchids in a sunroom, and in the summer the temperature can get to around 90 degrees F. I do not use my humidifier in the summer and with the windows open I do not have any trouble maintaining proper humidity for my plants. (It does get very humid in Chicago during the summer.) I also have a fan that blows directly above my orchids. I have had no problem with rot (so far!).
