Sealed hood ventilation

Discussion in 'Lighting' started by beardedbotanist, Jun 23, 2015.

  1. So I am running a 600w plantmax MH conversion bulb in a sun system xxl hood. I am currently running it 23/1. I have my ventilation going...
    Carbon filter-fan-duct-hood-duct-out of room.
    My question is...
    Do I have to run the fan the entire time 23/1 the light is on, or can I run the fan on 2 hours off 1 hour?
