I have only tigrina. I grow in the basement under MH HID lights year round. The temps range from a low of 60 F. to a high of about 80 F. in the summer. Under these conditions I bloom phals, phrags, paphs, cattleya alliance, oncidium alliance, dendrobiums, vandas and gastrochillus. There may be one or two others that don't come to mind at the present.
