I can't thank you all enough for the nice comments. Maura your absolutely right as to the on going pursuit of orchid happiness. I still am having one more Grow Light installed in a week or so (for next winter) and a fairly large 3500 window mount evaporative cooler installed at the same time for our hot, dry, long summers. Not only should that cool the greenhouse, but it will add more humidity also. Thanks again you guys! AL
