check out the home improvement stores they carry inline duct fans that are really easy to wire up to a plug and timer. cheap fix. I have to open my box :jointsmile: during the light phase to help with heat, but I have 60k lumens in a small box. I am sure you lose a bit of light but its a quick fix depending on your location.
