What would be the best way to ventilate all chambers in this non-standard cabinet?

My cab is finally built and sealed - Pictures soon, I promise!

Next up: Painting! Before I get started on this, though, I need to get all of the holes drilled for my ventilation system - That's where all you sharp folks come in.

As I've got a fairly non-standard setup going on in my cab, I'm having a hard time figuring out how best to get fresh air in and stale air out of my veg chamber, flower chamber, and utility room. Here are my options as I see them:

Ventilation Setup A

In this setup, air enters the vegetative chamber, passes through to the flower chamber, up into the utility room to cool off the ballsts, then into the ventilation room to get scrubbed and pushed out of the cab. One straight line all the way through. It's pretty simple, but I'm sure there are problems with this that I haven't anticipated - Enlighten me!



Ventilation Setup B

This one is a bit more tricky, but allows for a more modular and efficient approach - At least I *think* it does. Air intake occurs in both the veg and flower chambers individually and "meets" in the utlity room, from which it is pulled into the ventilation room, through the scrubber, and out of the cab. My concern with this design, however, is that the air flow will take the path of least resistance through either the veg or flower chamber, whichever it may be.

What are the dis/advantages of each? Thoughts? Suggestions? Ideas? I'm stumped!

i would say "Ventilation Setup A" is best, due to the air flow path of the veg chamber not going through the utility room, on the plus side, the veg chamber dont smell as stronge as the flower chamber, so im thinking that theres no need in taking a chance that the main airflow path will go via veg room.

you could try it though, if it fails, blank off the veg to utility chamber hole.

Just to make sure you didn't mis-understand my shite MS Paint illustrations, in Setup A, the veg chamber airflow *does* go from through the utlity room - after passing through the flower chamber.

I would want every bit of moving air to make it through the cool-tubes. That would be 'setup A' with holes in the veg room floor instead of the flower room floor. All you have to consider is the light-trap between the veg and flower rooms. Many use PVC with some elbows.

That's pretty reasonable logic. Plan is (if I go w/ setup "A") to use PVC tubing to draw the air from the top of the veg chamber down to the bottom of the flower chamber. From there, it'd go under the slideout shelf to about the midpoint of the flower chamber, where the air would output. Sound solid?
