I've had this one for about a year now and it is sending out a spike to rebloom. I grow it in a window with other orchids, including phals that rebloom. The humidity stays above 50 and the temp drops about 5 to 15 degrees from day to night as we try to avoid air conditioning and heating. Lowest temp in window in winter is 60F and highest about 82 in summer. When I last checked, the light levels, they were in the 500 to 1500 foot candle range. Mine is mounted and I water it once a day. It completely dry the next morning even though there is some moss on the mount.
I noticed you live in SF and we both get water from Hetch Hetchy which works well for orchids.
Oh great okay, thanks!
I didn't realize that our water was more beneficial, is it because there are less salts and minerals in the water?
