During the summer it was staying about 8 degrees cooler than the outside temp. I put the defused poly carb over the glass windows. The auto vents stayed open all the time. They just open more in hot part of the day. I did not use a fan at all this summer. The vents had enough chimney effect to do the job.

I have now taken the poly carb off the glass windows. It is cooling off at night and getting hot during the day.

The vents close at night and open the daytime. So now it stays warmer at night and cooler in the daytime than the outside air. This time of the year it just makes the temp changes milder.


I have the system running good enough to support the deep water culture. I need to get starting plants every couple weeks to get to my goal of a constant lettuce supply.
