I'm in the research phase of developing a new grow room and I hope you guys can help out. I have a 13ft wide room by 14ft long. Given this dimension I can fit more trays if I use the 3x3 trays, but then heating becomes an issue because if I need one light per tray, that would mean I would need around 10 to 11 lights total. Is this too many lights given the size of my room and how big of an AC unit I would need to cool it?
