Hey everyone, just putting together my room. I have 1 1000 hps , already flowered and wondering how long Do I have to keep my exhaust fan on for? First grow.

Thanks everyone for help and info

through your entire flower stag. when your light is off your fan should be off, unless you have high humid and temp at night.
