1) If I'm pumping Co2, even small amounts, into a sealed environment, am I not creating a positive pressure that needs to vent.
2) I like the idea of a balanced louver that is pushed open by positive pressure. Anybody have a picture of that?
3) Is there a need to do air exchanges in a closed loop system?
Living in Southern California. I am in ground zero for insect infestation. I have lost crops to aphids, whiteflies, budworms, spider mites and even fungus gnats. I am going with a closed loop system this winter with automated control. I am trying autoflowers to limit my exposure time. In 2020 I built a 10x20 outdoor screenhouse., I watched in horror in September as tiny whiteflies crawled thru the screen. Soon, I reached the seasonal limit for spraying spinosad and I had to trash (6) 7' tall plants that would have yielded kilos. My determination to suceed knows no limits.
