If it is any consolation, I grow outside, so the RH is what it is, I can't do anything about it. Since early November, the mid-day RH is maybe 30% maximum, some days it has gone down to low single digits - with high temperatures ranging from 95 deg F at worst to about 70 deg F when it's comfortable. Forecasts look like more of same for several more weeks. Nights have also been quite dry (one aggravating factor for all the fires, alas... ). And even the sensitive plants such as thin-leaved Pleurothallids are fine - I just water well in the morning, everything is dry by nightfall when temps drop as low as 40 deg F or a bit lower. The mounted plants, and the nearly bare-root cold-tolerant Vandas are doing quite nicely in low RH. Orchids are tough and adaptable!
The good part... flowers don't get botrytis when temps dip at night.
