I have a tent thats 4'x3'x8' (aprox), and i am not really getting the most out of it. I now planning on laying down my tent, and using a hood to get closer to the plants and do more of a scrog setup. Will leaving one side of the hood open work well? If you need any more info please ask. I only have one 6" fan and I believe its 355 or 455 cfm (can't remeber right now). Any advice at all? I live in the bay area so temps don't get too extreme.
