Hi, I'm new. Just checkin out the website. How do you view the classifieds? I'm interested in general room setup equipment, not seeds/plants or anythings. :confused:
Only a split-system will do what you want. Uses refrigerant so no air escapes that way. All portable and window units will exhaust the air and odor. Split system acts like a fridge for that room. High BTU and high CFM can cool large rooms with lots of heat.
