No fungicides here either. I'm growing in a 48" x 18" x 18" tank with no lid on and a dual 48" shop light on top (also lit by CFL's). Humidity is provided by a mister unit in a ceramic bowl set to be on for 15 minute intervals throughout the day as well from water trapped in eggcrate across tank bottom. One fan blows across the mister and resevoir while two others are hanging from the top and don't blow directly on leaves. With the lids on I can maintain much higher humidity 75-95% but due to spikes growing too tall and damage to plants I have removed them (now only 55-75%, but I mist/spray manually as well). I've tried to inject cooler air from outside but not very successfully. My saving grace for this type of setup is my cool-ish basement which is warmer in the winter and cooler during summer months when I turn off my furnace. My grow area doesn't usually experience extremes in temperature (outside +32 to -48 degrees C, inside +27 to +12 degrees C). Another benefit is that by keeping the resevoir full a plant sitter can maintain my most thirsty orchids when I do travel.

Here's part of it, mostly Pleurothallids on right and Miltoniopsis and Oncidium intergerics on left.
