They are in a hall way and the air is likely being sent back into the room with a mix of fresh air. I can extend them further. I'm also considering venting some air from outside at least in the cooler season, summer is a different issue but I usually don't grow in the summer. I think it best I leave them the way they are until I fix my watering issue. That way I'll get a better idea of how my changes effect my grow.

Thats what i thought... that the exhaust would mix with the fresh air. But... that didnt work for me at all.

Trust me....you will need to find a way to either exhaust outside or to pipe in fresh air in from outside... one or the other, preferably both.

Unless, maybe... you can exhaust way way far from your space.

I can post some pics later of what happens when plants are starved of co2... it is truly sad and embarassing...
