It was a 3 step process that transpired over the course of a week and a half as I slowly adjusted things with it a little here and there.

1.) Simply introducing the plants into the grow room cooled the temp by 2 degrees. I think this is mostly because of the cool damp soil. I water them every other day with 48 degree water at a 7.0 PH level.

2.) I removed the ballast from the grow room. That dropped temps about 1-2 degrees.

3.) I trimmed a few feet of ducting off of the blower fan to give it a little more horsepower. This did me wonders as it dropped temps down about 4-6 degrees. The seals to the blower were not air tight either, fixing that halped as well.

So in short... I introduced plants, removed ballast, then fixed the blower ducting.
