Only in enclosed spaces. Depending on the natural humidity of your area, you'll have to dump the small units daily unless you set up an auto-"dumping" tube system. It's good for keeping mold growth down in enclosed spaces though. Disclaimer: I basically live outside in a costal region. I dump the thing literally daily if not twice. The plants love it. For your purposes it would work. I can recommend the cheap amazon waykar unit. Comes with a tube system for consistent water disposal, as long as it's ground level. Embrace the day to few-day disposal process and it'll work out.
