Hello all! I'm wondering about increasing the humidity around my small orchid collection. I grow on a homemade grow table that has built in humidity trays, always about half full with water, sitting in a south facing window with a sheer curtain over it. I have a thermometer/hygrometer that shows my humidity ranges from 30-45%, temps from 66 to 75 degrees F. I live in Cincinnati Ohio, and am growing phals, a seedling Catt, and a psychopsis (oncid) papilio. The phals and psychopsis are blooming, seedling is too young, obviously.
Is the humidity ok for these plants? Can I use a cool mist humidifier? it's winter and my heater is on, so I know that it's going to be a battle...
Also, I'm hitting 2 orchid shows in my area in the next month and plan to buy a Catt, paph, and possibly encyclia. I know their light needs will vary-- my grow table has 2 levels with a grow light over the bottom level, and I have some ideas--but do you think the temp/humidity I can provide are ok for those additions?
