Please critic my small grow room

400w cool tube w/6" ducting/Filter/inline. It pulls cool air from the room it is in and blows it into the next where it dissipates in the large area. Tempts are ranging between 82max and 72min.

Any thoughts or suggestions?

At that stage I would raise that 400 watt a bit higher for those seedlings. Other than that, looks like youre set to grow some herb IMO Happy growing!
