Maypop " They should be coming in at night if the temps are dropping below fifty but can still enjoy the nice days. Bright outdoor light will make for better blooms even if you can't get them out every day. Oncidium and Dendrobiums can take full fall sun if they are used to bright summer light. Phals like very bright, indirect light or several hours of early morning sun. If you bring plants in be sure to put them someplace cool at night so they have the temperature swing they need. Fertilize with an orchid fertilizer weekly to encourage bloom set and allow all three of these orchid species to almost dry between watering during this cooler period. Always water the plant first and then fertilize to prevent burning roots."
