Best way to keep humidity up for clones

I built a stand to store supplies and other things for my grow room.. in part of it I made a clone station, put in t5 lighting, doors on it to seal it up etc. I am able to keep temps around 80-83 inside with lights on, its large enough for two clone trays. I was hoping to be able to not use the dome's and just keep the humidity up. I sealed the walls/floors of the wood already as well to protect it from moisture. Ideas what to use to keep humidity in there around 80 or so?

thanks all

Heat mat under your trays.......I would think condensation may be of concern around your lighting prongs though, why not use the domes?
