Lower box temperature

[rodantas]

Hey everyone so I have a small grow box and the light I use in that grow box is a 150W CFL (only one bulb with 150W)

To make the box cooler I use an extractor with 190 m3/h

Right now the temperature of the box is 82.4°.

What can I do to lower the box temperature even more?

Thanks

You could try increasing your intake vent to get more air going through the box.
