Very nice job JS. I wonder if this could be scaled way down to keep the stealth of the cab? Again great freakin job contrats on the successful build.

Okay time to get serious about venting and duct work. You'll notice me using flex tubing along the way. I just use this to test things. However, the final ducting will all be 4" PVC. The smooth inner surfaces definitely cut down drag and air friction.
At this point I'm using flex tubing to get the cool tube exhaust to the port in the wall. Some shots looking up.
Up until this point, I had been connecting things to the cabinet using the inline backflow fittings (like the one attached to the wall in the first pic above. However, I found that sanding the hole a bit bigger, I can get the 4" PVC to slide in and give a really good tight fit. I then use a straight coupler which my inline fan assembly fits into perfectly.
It's coming together nicely. You'll note all my 12v wires are all ghetto right now. Once I get the ventillation up, I'll start making clean power runs to all the fans.
Notice all the tubing coming down. Since all connections are semi-permanent, making adjustments is super easy. I have many options on where I can pull "clean" air and where to dump "dirty" air.
We'll talk a bit more about the overall "air plan" in a bit.
It truly feels like you are sitting in line for "Space Mountain".
So whatcha think?
peace

WOW!!
A lot of thought went into that!!
Nice work!

Okay the next post isn't for the squeemish. If you don't like blood and stitches...move on.
I was working on one of my side projects to insulate the garage door with rigid foam (pics coming up shortly). I was cutting the foam with a utility knife while yacking with the wife (about good stuff)
and just lost concentration for one second and fffffffttttttt, the knife just laid right into my thumb which was carelessly sitting in the way while holding the straightedge. The foam boards are 4ft wide so you have to shift your hold on the straight edge as you move along the cut. I usually hold things down with my knuckles since it keeps the fingers out of the way....like I said careless.
I thought about just wrapping it up and letting nature take its course but I figured it was deep enough where the skin flap would probably turn black and fall off leaving a big hole in my thumb. Add to it the skin flap would eventually dry out and start getting caught on everything like a huge hang nail. So off we went to the emergency room for 4 1/2 hours, $100 deductible, a nice conversation with a cool doc and 4 stitches...3 of them directly in the nail!
It's pretty funny I can go all day working and come away with scrapes, cuts and bruises that I have no idea how I got them. This one got my attention!!!! Thank goodness I've taken about 10 First Aid/CPR classes (keeping me from freaking out) so I had serious pressure on the cut from the start. Isn't marvelous when special training just "kicks in" and you do the right thing without thinking about it!!
This is all just a day in the life of a DIY Cabinet builder!!
As you can see it hasn't slowed me down...much.
peace....and for goodness sakes be safe!! It just takes a split second to die!!

Man!!! Take care of that thumb!!! I did something very similar one time.... Only I opted for no stitches. Well it kept bleeding for like a week or more before it finally closed up! Well I think you did the right thing!!

Haha looks like you've been working hard, things are finally taking shape for you i hope 
exceptt you thumb which has probably changed shape heh heh heh ... dont worry we all do it i nearly cut my finger off with a stanley knife when i was wiring the flex connector on my reflector. just let the scar be a reminder of the effort youve put in

Very impressive build! I have a question for you about this rigid ducting. It makes sense that you are using it for reducing drag. However I wonder if you might be better using flexible ducting inside the rooms if you ever intend to change the height of the lamps. I imagine you have considered this, but do you plan to move the lamps, or the plants, to keep them inside the brightest area around the bulb? Or is the system going to be totally fixed, in which case how will you deal with over-vigorous growth into the bulb and prevent burning?

I never knew just how useful my left thumb is!
I went to go get my stiches out and when the nurse cut them, the wound popped open again. She looked at me sternly and asked if I had kept it dry. Looking back at water changes and all the other crap working in a hydro environment I had to fess up (if you go back to my grow journal you'll see pics with the bandage off). New stitches and water tight tape for me.I'm an idiot after all!!

Hey that's it! I just needed a bigger scar to make my war stories more dramatic. Can't you see me in 30 years (in an old geezer voice) "...back in '10 during the great marijuana war of California ...."
Yeah and sometimes I wonder when it will end.
The worst part is all the stooping, bending, reaching, twisting, etc. I try to run 3 miles a day with no issues, but working on this cab for an hour makes my body feel like I ran a marathon. But truly it's satisfying work when it's all done (and the pain isn't that bad 
). 
Leo. Does that make any sense for you? Next time you look my horoscope up, keep in mind my creativity is "iterative". The idea may be good but it takes several times to get the right implementation.@ jsgamber - u gt sm creativity man...keep it up...superb ! jst loved ur wrk n d detail of it....wts ur zodiac sign...? best of luck fr ur kompletion n growth...
Thank you for giving me your time and welcome to the collaboration! Make sure you go through those guys journals too. They have ideas and information that I have used along the way. Also they have taken some of my ideas and made them better!
Hey Stealthboy! Make sure to check out my grow journal to see how my cabinet functions and my use of mini reservoirs.Very impressive build! I have a question for you about this rigid ducting.

My chambers are 35" high and my reservoirs are 9" high giving my 26" of grow space. Because of limited space, the lights are fixed in place so rather than lowering lights I just raise the plants. Besides 250W is a bit too intense for clones close up.
In my mother/clone chamber this height is perfect because the moment my mums hit the ceiling they get chopped up into clones.
My flowering chambers will be running SCRoG and I'll be putting my clones straight to flower as soon as their roots are established. The flowering rez will be 13" high (with screen) so I'll have 22" to grow buds! I hope they hit the lights 'cause I want an excuse to have to cut some samples!
However, I'll probably put a screen around the tube to deflect.With the mini rez's, I can re-arrange them any way I want to get the best lighting.
Let there be light in the first flowering chamber. In other words, let there be HEAT!!
After getting my 430w Sun Agro hooked up, I closed up the cabinet and sealed it up with Duck tape to run a test. I don't yet have the door seals in place. Unfortunately we hit 100*!! My mother chamber above hit 91* and fried a couple of my clones. I'm thinking I may have AC in my future!

what if you had your cool tube drawing the air from within the cab, working along with the exhaust? But only do it for this one cab. It would be an easy and cheap test, even if you dont have caps for your holes, just use duct tape. that or try to shuffle lights so that the hotter higher wattage lights are on top, decreasing heat and wattage on the way down. i think you already thought of that though, cant remember, so many threads... everything is looking good though, excellent duct work, you should do HVAC!!!
Did I mention my garage door is west facing and is made of aluminum and is in direct sunlight for about 4 1/2 hours. By 4:30pm the door can't be touched, the temp for the first 3ft inside the door is 95* plus making the back of the garage between 85-90*.
To solve this, I installed the same 3/4" rigid foam insulation that I built my rez coolers from. The result is amazing! Garage temp at noon (before direct sunlight) was 75*. At 4:30pm it was 76*!
Now to garage ventillation. The garage has two vents on the north (cooler) facing wall. After much consideration, my plan is to exhaust out the upper vent and let the bottom vent remain passive. I'll be building a custom fan box over the upper vent.

Hey gumball,
I tried that test on my 250w chamber and it actually got worse. The cool tube works best if it's drawing it's own clean air rather than dirty air from the cab. It just took higher cap fans on the exhaust ports to keep things in check.
I may be looking at using those Ultra Kaze fans on the exhaust ports for the flower chamber! Either way I'm going to need some more air flow!
But before I can test it out, I need to get the doors sealed up!
Keep throwing out ideas (cheap please)
But like I said, It may come down to AC. Time to find some cheap portable units.Oh I already have them for the cool tubes. But I bought the 100cfm for cab exhaust. I may need an upgrade and I may need one that takes me out of PC case fans
But I still have some testing to do. I'll know better once the ambient temps are good and I get that flower cab set up. Those flower cabs need to stay at most 85* but I'd prefer 80*. At least I won't have to worry about keeping humidity down.
I've been doing quite a bit of research on ventilation with fans, static pressure, Equivalent Duct length, etc. Here's a pretty good guide http://lib.store.yahoo.net/lib/rewilliams/ventilationfanguide.html. I've also been trying to nail down how much cooling I will need based on HID lamp output and ran across this article as well http://www.aquaculture-hydroponics.co.uk/admin/web-inf/uploads/documents/cooling-bound.pdf.
As my research is nailed down I'll fill you all in!

are your other walls insulated in your garage? how much did insulating the door help your cab temps? i know, i am full of questions!!Did I mention my garage door is west facing and is made of aluminum and is in direct sunlight for about 4 1/2 hours. By 4:30pm the door can't be touched, the temp for the first 3ft inside the door is 95* plus making the back of the garage between 85-90*.

Yes as well as sheathed in OSB with 5/8 drywall over that. The mum cab used to climb up to 90* and now it goes no higher than 80 (and that's probably when the garage door is open for awhile) but mostly stays around 78*. Garage ambient temps are currently around 73*. Bottom line, it was a significant difference for the afternoon temps. I only used 3/4 foam at a cost of $8 per 4x8 sheet.
By all means keep the questions and comments coming!!!! If I get no comments I don't get motivated and if I don't get motivated I do no work and I have no pics and if I have no pics I start to feel guilty which reminds me I need to keep growing weed....wow what a nut case I am!!
