I don't have a hygrometer, but I am pretty sure the humidity gets pretty low in summer. My Catts, Coelogyne, Phal (if they don't get burned) & Oncidiums do well, but I think my other plants suffer from low humidity. I am trying to grow quite a few pleurothallis, and a few mounted orchids.
My greenhouse is freestanding, and I only have a garden hose able to run to it - so preferably I can run something with a resevoir.
Does anybody have any recommendations on a humidity system I could set up? I am not picky about if its fog or mist, but it probably shouldn't be a warming / steam type humidifier.

If your greenhouse is small, buy a Hydrofogger (or Two) You plug this device in and it spins humidity-laden mist into the air. It has its own mini reservoir and float valve, to keep the reservoir filled automatically. The problem with an Aquafogger is: unless you have a lot of distance between the Aquafogger and your plants, they will be constantly wet..a problem. Stop obsessing over your garden hose, and get a plumber (or do it yourself) to install a 1/4" OD swamp cooler hose bib (in place of your regular hose bib (that connects to your garden hose. Then you can connect a 1/4" OD poly tube to the small 1/4" outlet on the new hose bib, and run it to your Hydrofogger. Yes, these things can leak, but mine never has...just keep the line out of too much hot sun (i.e., bury it or cover it) and it will function for years.
By the way, you'll need a humidistat to regulate the on-off cycles of the Hydrofogger.
