Inside Exhaust? What am I not getting..

[GrassNewbie]

Just take intake air from the same room you are exhausting to. The exchange is what is important. You will also benefit by heating your home during light time.

I had NEVER thought of that... I'm actually shocked by the idea, it would solve all my problems.

Can you guys elaborate more on the idea? Why haven't I seen this before? :thumbsup:
