ahahahaha just a tab bigger wouldn't you say? I'm pretty sure with only a coolmist i won't have trouble keeping the humidity levels up to casing standards. For FAE I'm using computer fans rigged to a spare power supply. I might just use a ultrasonic plus the fans, seems more appropriate. I'll use it on a low setting with fans going 24/7.

Wo0t, first post.. So ya, I've quite a bit of experience with LED's.. Not in their application to mushrooms as such, but I have studied them and separately their application as grow lights, etc...
Quote:
nalyudi said: ive read that most production white led's (which are actually modified blue led's) put out blue light from around 450-470 which is just a little shy of the parameters listed on this site. i think in the clear rope, if they are in fact "white" led's, they will work fine. good luck.
^ This is partially correct. (Most White LED's are in fact blue with a yellow overtone, giving a white appearance.) You say if they are in fact 'white' LED's. If what I understand you mean by 'white', this is improbable. It's highly unlikely that those strips will incorporate full-spectrum LED's (White light is composed of the full visible spectrum)
Quote:
they wont be bright enough.
Not entirely true... Colors such as blue or red are located on the extreme ends of the visible spectrum, thus they are harder to detect with the human eye. That's not to say they arn't as intense.
Quote:
LED Rope lights give the most amount of light with least amount of power consumption
Oh how true At least to that specific wavelength. Gotta love LEDs 
Quote:
FYI: white spectrum contains all colors of light. Your mushrooms will certainly get more than plenty of 420nm blue light from a full spectrum bulb to give them direction upward.
Indeed. Unless the exact wavelength of beneficial light is known (Maybe 420nm was mentioned?), I'd say just go with multi-wavelength sources.
Quote:
color freaks me out. my pen isn't blue. it adsorbs everything BUT blue!
heh, ya:) Why's chlorophyll green? (Thus green lights are used in grow rooms where absolute darkness periods are required, as it doesn't upset the sleep cycle.)

shroober, the light rope i was talking about might be incandescent, it doesn't say whether they are LED or incandescent though...

if it doesnt say LED then it is almost certainly incandescent, i would strongly suggest against incandescent, especially if you plan on using them inside the FC, they just get WAY too hot

yea thats true... they also have 2 foot fluorescent daylight's with ballasts at walmart. 12 bucks with 4 buck replacements i might rig this on top in a see-throught tub with some extra PC fans pumping the hot air out of the box. Should work in theory.
