@GrowinOld: Oh, I totally intend to set something up at some point down the line. No joke. I'm going to have speakers hooked up to a thunderstorm soundtrack, a strobe that randomly lights... all the pumps will kick on at once, maybe have an extra fogger just for this that also kicks on... For all intensive purposes, I intend to simulate a thunderstorm in the GH. Some day when I have a couple hundred extra dollars laying around to accomplish this. XD But seriously, I want to at some point, and I think it'd be soo awesome. Especially at night. I am also going to hook up a few low-light LEDs to simulate moonlight at night (not because I think it'll benefit the plants, just because I like going in there at all hours of the night and I'd like to be able to see without kicking all the bright lights on). Can you imagine being in there at night, with the simulated moonlight, and suddenly a thunderstorm kicks in? Way too cool, haha.
@nightsky: Thank ya!
