My plants are too close

[ookami]

I have just now reseted the thermometer, so I can check the low temperature during the dark period.

And now I have had a dark period since reseting. 68°F when it is as coldest. That's the room temperature I have. The humidity varies between 25-35%rh.

When it comes to ventilation, my fan moves 160m3/h according to the spec. If I convert that into imperial units, I get 5650 cubic feet per hour. Could that be a reasonable figure? I think I have mostly seen lower figures here on this forum. Anyway, it sucks sufficient air to make the tent walls bulge inward, which I consider a good thing. Then all outgoing air will pass the carbon filter. It seems to work. The only times I can feel the cannabis odour outside the tent, is when I have been handling the plants.
