I recently got into Orchids. A couple of years ago I bought some Phals at Home D. that never re bloomed. Last year I built a room off the bed room with all windows facing NW. I ran Air condition to it but no return. I moved the Orchids into that room this year on stands next to the windows. In the day the temp stays about the same as the house approx 78, at night I open the windows and let it drop to night time temps. Just for the summer.
I get afternoon sun and evening sun. Right now I have 4 phals out of 6 in bloom and all are doing well. This month I added a Sherry baby, Max tenuifolia, Rlc. Chia Lin, C. Warpaint, Rlc. Susan Fender Ã¯Â¿Â½Cinnamon StickÃ¯Â¿Â½, Oncidium Twinkle - red. These new ones are blooming size.
My question is about light. The windows are double pane Low E meaning coated. I get evening sun most but not all filtered through a tree then the window. I can measure the candle power but since the windows are Low E will that filter out beneficial light? It appears not to hurt the Phals. Since they are blooming since I put them in the room. I do not know if its enough light for the Sherry Baby and Max tenuifolia. I will measure the CP and post tomorrow.
