My goal for this setup is to make some of my highland Neps happy. Most of my Neps do fine in my basement conditions but a few, such as N aristolochioides, need it colder. I haven't bought anything for this setup yet. I'm looking for feedback on how you think this will work.
Enclosure: Darkroom DP90 Propagator - 3' x 2' x 2'. I like that this is a compact enclosure. I wish it was another foot taller but I couldn't find anything between 24 inches and 48 inches. http://wormsway.com/detail.aspx?sku=DP224 $80
Lighting: T5 2' 4 bulb fixture. I don't have a brand/model picked out. ~$100
Cooling: 8000 BTU window A/C unit through one of the windows in the enclosure. Free, already have an extra one lying around
Humidity: Ultrasonic humidifier, I don't have a brand/model picked out. ~$50?
Temp/Humidity Control Zoo Med HygroTherm seems to be the standard. ~$70
Total cost: about $300
