I was a volunteer EMT/firefighter in high school, and before the military. Then I used my GI Bill to go to college for my RN. I bounced between infectious disease care (mostly TB and HIV/AIDS) and psychiatric nursing, but have also worked with hospice care. At first it seemed really strange having immuno-compromised patients on the same floor as highly contagious ones, but negative pressure isolation rooms for TB, and positive pressure isolation rooms for the HIV/AIDS patients. Then it was our job not to cross contaminate. That was my first job out of college, and it was still the early 90's. The AIDS epidemic was still new more or less. It makes me laugh to think about it today, but back in those old days as an EMT, Universal Precautions hadn't even been implemented yet!
I wish that I had the room to run multiple tents. But I live in a tiny apartment, and had to break down my home music studio in order to make room for the small grow op that I have. Interestingly, my tent running negative pressure is cooler than the air temp of the room. When I open the tent to look at the plant, the temp can spike 5F or more. (And I have a 2000watt
Bestva led in a 3x3 tent).
Thanks for outlining your air pressure management. It gives me things to think about.
And i definitely want to thank the OP for posing the question. It's been quite interesting reading the different opinions.
