Jungleboy- I've lived both in the desert, and in humid spots where it could get to 65% humidity. My plants have done a lot better in the desert house than super humid, because once humidity rises above say, 40-45%, thus begins the delicate balance of trying not to overwater, and also avoiding fungus growth on the plants. I think 35% is optimal for plants. If you have certain ones that need more humidity, maybe try a small indoor greenhouse for those plants.
You've got the experienced people answering above- lucky day!! They have good ideas.
Edit: I just have to say....Gene....2000 plants? Wowee! I think that would be the point my husband would say, "Honey, I can't find the door". I would answer "Take a left by the ficus and a right by the monstera then go down the pothos walkway". Just teasing- must be very cool!!!!
