GG84 you are right, I do have two of the same fans, one running in and one running out. I guess my idea was that one could pump in cool while the other pumped out warm, but I suppose that is an inefficient use of the energy. With the use of negative air flow I can move twice the air with the same amount of energy.

I am going to try that tonight and I will update you on the temp change next time. Lets pray for some cute little sproutlings for the AM.

Golden, I won't make the mistake of thanking you for the help again.

Keep the peace everyone.
