I have often considered trying to hook up an evaporative cooler for small
special setups such as Darlingtonia or highland Nepenthes. It would seem to me
that a small submergible pump and a fan operating on the same timer could be
hooked up, perhaps using a loose weave fabric as the evaporator. Has anyone
tried this? How about the growers with greenhouses - has anyone made their own
big unit instead of buying one?
