wiring the fixture will be the same as wiring the inline fan. acquire a grounded extension cord, and you're set.

there should be little rings around each socket. these will pull (or unscrew) off. remove all of these, and the front of the fixture is free. pull it open, detach the ground wire from the fixture, and color match it to the extension cord's wire (black to black, white to white, green to ground). then the negative, then the positive. electrical tape, wire nuts, and you have a CFL setup.

oh, ps, i've seen humidity readout strips at petco for terrariums. like $2, i think. you can also buy pH test kits there, as well as pH up and pH down.
