I live in North Carolina and it gets close to 100 degrees in the summer and the building I plan to grow in doesnt have air conditioning and I wanted to know if there was a way to get cold air into my grow box. The box will be located in a closet of the building. I don't have enough money for a portable ac and I can't pull cold air in from outside because it will be just as hot out there. I've looked around on many other forums and just can't find the solution. Anything will help, I can't cut holes in the walls or anything because it's one of my buddies places. Thanks in advance.
