position the ballast outside of your growbox, and if you can put a fan on the ballast . it gets hot
mobay Reviewed by mobay on . ballast question? I was wonder who out there could tell me if it is possible to position a ballast in any postition,Or are there ballast's that have to be positioned vertical or horizontal.the bulb socket (large base) is fixed to the ballast.Therefore hindering me from using it in a horizontal relflector.Much like a hydrofarm,reflector.Any input would be an asset!
