| Desertgal - Okay, I just did the test myself with similar results. This morning I started with dry trays and showed a reading of 51% humidity in the room/area where my orchids are all gathered together. After filling the trays with water I have been monitoring for the last half hour and it is stabilized at 63% for the time being. I do have forced air into the room and also a small fan about 10 inch square or so blowing in the general direction. My guage is placed in the middle of one of my levels/group of plants - at plant height. So, based on your and my tests it would appear indeed that we can affect the humidity by AT LEAST 10% This is certainly not as beneficial (will not raise into the 70-80%+ range) as those fortunate enough to have a greenhouse, but still worth the effort - provides SOME "extra" humidity to our plants. Thanks for the challenge! mike |
