What are the potential problems for either positive or negative pressure inside my tent? Im purchasing intake/outake fans from htg supply soon and there are 2 sizes: High Tech Garden Supply and High Tech Garden Supply My tent is 2X4X7, 400w light, circulation fan
you want the more powerful fan as the exhaust to create small neg. pressure in the tent. if your tent is sealed, you shouldnt even need a intake fan. as the exhaust pushes out , it will suck air in from the intake hole.
