Here's one for you to think 'laterally' about?

 

Why do we set up grooms with the extraction at the top and intake lowdown?
And, is this really the best way to go about things?

Hot air rises...

So extraction at top to take out all of the hot air, the cool air circulates round the plants from beneath, fanning them like a chinese lord from tenko.

Smells linger better in hot air as well or so im told. Sounds sensible.

If the extraction is below the top of the space then it's likely that a layer of warm air will accumulate above it, and keep on getting hotter.
 

And, is this really the best way to go about things?


Arguably not.

It's almost exactly the reverse of what happens in nature, where the tops of the plants tend get the cool, fresh air and the lower parts sit in a stiller and more humid environment.

It's really difficult to control things that way, though.

Does farting in the groom help things at all?

My thoughts too.
But the only thing we are controlling this way is heat?

Rather than cooling the air straight away, and maxing the heavier weight of CO2 (it sinks not rises). And also getting a more stable overall heat spread. ?
