I can't say for Colorado, but I think in Seattle, you shouldn't have a problem - can be dry here, and mine have mostly done well - I'd use a skewer in the media, you can use that to check for moisture - it the skewer even feels dry, but cool against your cheek or lip - there's moisture in the media
I know Colorado can be extremely dry, but,maybe try the skewer in the media - I do know these can suffer from rot from being too damp
