This week I added a 4 inch duct on the lower left side right by the fan, so it pulls in fresh air from another room. Also, I made a bunch of 1 inch holes in my buckets, then lined them up with mold resisting drywall tape and finally I wrapped the buckets in shiny hvac tape, figured it would help with the light. I have 2 temperature and humidity probes, one by the canopy and the other one lower.
I must say that I was pleased with the progress so far.
