Should be pretty good for an inside grow room. I think the value of humidity really can be seen when air temps are high 85+ degees and humidity levels are above 50%.

Low humidity during dormancy doesn't seem to trouble plumerias at all, but they are more prone to spider mites when it's hot and dry during active growth. My summers are in the 80's and 90's, with lows in the 50's and 60's, and the humidity is very low, with dewpoints rarely in the 50's. I'm always on the watch for spider mites! If you keep your plants indoors all year you'll have to watch out, because air conditioners create extremely dry air.

Thanks for the input K and Michael. Nice to hear from you K :) Glad to hear the humidity here is on the safe side.

Hi Michael. Temp rarely goes above 75* here in the summer so no air conditioning. I'm paranoid about spider mites growing indoors like I do. Spray with neem oil every two weeks as a preventative- know they lie in wait and it's a matter of time. Any other suggestions you might have I'm all ears :)
