How much CFM to cool 1000w hps hood
i was wanting to vent the heat directly from my hood so that i could enrich my space with co2. i cuurently have about 72 cf(3x3x8) of space and my hood is standard size(2-3cf). could anyone tell me the amount of cfm i would need to effectively exhaust my hood. And about how much co2 should i inject into my space to reach 1500ppm?
