Debs,
I use a small heat pump. It looks/works like a window AC unit (drys the air), but includes heating capability too. I live in southern Arizona, so too much
outdoor humidity is NO problem, and most people here use swamp coolers. I
was concerned about maintaining enough humidity
inside the greenhouse when I first installed the unit.
No problem with this . . . the drying effect is
more than compensated for by misters (which I don't run all that much). I have no problem maintaining summer temp's at a max. of 85 degrees (this system
can keep it cooler than that, but that's what I want to maintain) and humidity at 75% plus, with day after day of 100-105 degree high's (sometimes even higher).
With the right kind of programmable thermostat, you have a lot of temperature control. I keep my greenhouse max'ed at 85 for the mid-day hours, then step it down to 75 for a couple of hours, then down to to 65 at night . . . reverse that in the morning. It works fine and the humidity stays up there for me. I think most of my orchids like that daily 20 degree differential too.
Hope this gives you some ideas.
