400 watt hps, open basement, need vent or fan?
This is my first attempt at using a hps system, I am hanging the light in a open basement, the rear and the sides will have reflective walls but the front and ceiling area will be open. Will I be ok with a small oscillating fan to move the air? or will I need to further vent to control the heat? I'd like to avoid running duct work, just uncertain of the amount of heat im going to generate. I have a plug in thermo stat for the fan but the wattage is low so I could run it off the lights timer for constant air circulation
