Hey guys, I am doing a grow right now and I am having to use two pretty needed arts of my house, which is causing some issues when visitors come. I didn't think I had an option until I discovered a hidden space in the house, but it stays very warm, it is similar to an attic. My plan is to build two makeshift rooms, on for veg and one for flowering out of a reflective insulation styrofoam type board. Then I'm going to set up a carbon filter and a can fan with some silencers on it for ventilation. My question is if I have these two rooms built, and have the air inside the rooms being moved out to the remainder of the space, will that keep the area inside significantly cooler? The temp is close to 100 up there right now due to the summer heat, so I just need to know if I am going to have that big of a problem trying to cool a 4x8 and 4x4 area.
