80 CFM or 50 CFM Panasonic Whisper Ceiling
Fan will be mounted to the top. I am not planning on using a scrubber, just want to take into account CFM loss with the PVC elbow inlets. Internal space again is a little less than 3 cubic feet.

I reckon both those fans are too big unless you are really going to run high power lights.
10 -15CFM would be heaps for that size cabinet, you can do that with a single 12V 120mm PC case fan running on 7.5v plug pack to keep it quiet. A single 120mm fan is all you need to cool an inefficient 400MH in a way bigger box than what you are building.

Funny you should suggest PC fans. Cause it looks like thats the route I am going. The Panasonic mounting brackets do not fit on the top of the cab. Guess when they said 10.25X10.25" dimensions it did not include the brackets. Total dimensions are 12X12" for the brackets. Lesson learned.

50cfm sounds fitting

Those PC fans are like 1/10th. of the price of the Panasonic, I know you said you weren't putting a scrubber on it, but what I do is mount the 120mm fan to a hole drilled in the cabinet near the top, and cover the outside of the hole with one of those 7inch round charcoal filter replacement units they use for kitchen range hoods. It' gives a bit of filtering, but the main use is to suppress the light that would shine out the fan hole if it wasn't there.
This kind of filter:

That's an expensive example, they are normally half that price. Just search on "charcoal rangehood filter"
They have a thin layer of activated charcoal pellets, about 1/4" thick, it wont absorb a stinky garden, too many gaps in the pellet layer, but it's better than nothing.
There are rectangular ones as well with more surface area on eBay, Amazon.
Didn't need a light trap with them, it was dim enough. They have a dark mesh layer that kills most of the light.

That setup looks hella tidy, Man. What you growing in there? Any thoughts about mediums/methods yet?

Thanks! Choices on strains are between Blueberry, Northern Lights, Harlequin, or a local mystery strain (think Skunk #1 lineage). & maybe Bubba Kush. Love the classics.
As for mediums, I use soil. Mixture consists of:
EWC, homemade compost, perlite, and a soil base.
Molasses is dashed in there occasionally during the grow. Real simple.
Methods are TBD.

Alright, LEDs mounted!
Right now running (4) 8.5 watt Phillips.
For fun threw in both the 2700k (left) and 5000k (right).

Mr. Sparkle
Looking good, i should of chimed in sooner but didn't think about it till this last shot, but from my past experience your probably gonna have about 10" of that space being unusable due to light penetration and tendencies of the plants to stretch for the light especially when grouped together, well if running say 4 or say 9 plants that is.
Id still run it as is, but you might find your gonna need to lower your lights or raise your pots/tray, just a fore warning
And if you do, you could easily make a tray style carbon filter that could tuck right behind the lights.
I loved building in that way as designing around the fact that hot air rises even with a fan fail it would still circulate air, and in general they also just run cooler.
Also i'm not sure how your keeping the door shut, but i use to use some locks called tot lok's that were magnetically activated so there was no apparent locks or hinges on the out side, they worked pretty slick when setup properly, i used them in conjunction with some double roller catch's to firmly keep the door shut and air/light sealed, and even when the magnet was in the proper place for opening up the doors, i would have to give them a slight tap or push to unlatch, which was pretty neat as you had to know how to open it to get in or you wouldn't without excessive prying.

hang a shelf haflway, grow 2 plants

Thanks! Yeah, totally forgot to mention. I will be using shelving brackets to adjust the height of the bottom tray. I recycled them off of some deceased cabinet.
As far as the door, I have already installed a latch (Pic near bottom of post #18). The tot lok your speaking of seems awesome, although I am one of those people that would lose the magnetic key in the first week
. That setup sounds like Fort Knox to a nosy household guest, which I like. I might use something similar for one of my next projects where I focus on stealth.
