Update:

I have sprouts. 100% germination. All of them are sticking about 1/2" out of the soil now. So 4 days to sprout. Excellent.

I bought 2 of those high-flow Delta 90mm fans and replaced my old fans with these. Ambient (not surface) temp in the container is now 82 degrees. :rasta:
The con with having Delta fans is the noise. Not even a fraction of the noise of a typical oscillating fan, though - just that high-pitched whirring sound from the motors.

I thought I'd add that I'm using a 150-watt miniATX power supply to run my 12 volt fans. I tested it with the three fans running and it is drawing 90 watts.

PSU=90
(3) CFL 30w Day=90
(2) 21W Warm White=42


Roughly 250W draw off of this unit only. :thumbsup:
