My dresser grow box

Hey guys this is gonna be my first grow, I'm gonna keep a journal here from building the grow box to the harvest. I hope that yall can give me advice on my set up I plan to use. I've done a lot of research so I'll try not to ask too many dumb questions.
This is gonna be done in a dresser that is about 2.3' wide, 1.2' long, and 3.3' high. It's not a ton of space but I'm gonna try and grow 2 plants, in a auto-pot set up. As of right now I've picked northern lights. I'll hollow out the inside, cover it with mylar, and create a secret door. It will all be sealed properly and sterilized.

For lighting I plan to use a 250w son agro bulb that will be in a ventilated glass enclosure seperated from the grow.

For ventilation I'm going with a closed system. The grow box will have 2 holes drilled in the back for an intake and exhaust hose, which will route to another location where I will have my own home made little climate control, as well as the water reservoir and co2 container. This is how it will work: The hoses that run from the box will be routed to another enclosure I will make that will have two 6" inline fans(250 cfm each), one for exhaust and one for intake. I will make adaptors to fit the hoses to the fans, there will be bottle necking though because the hoses from the box will be smaller than 6". Then I'm going to take a small mini frigde and drill 2 holes through the front. Then I take a plastic bottle and some pvc pipes and hoses and make what sort of looks and works like a bong. It will sit in the fridge filled with water being cooled, the exhaust will be pulled through the water and out the top back to the intake. So the exhaust fan is on the left, it draws the air from the box, that leaves the fan and goes through a tube that runs through the fridge, throught the "AC-bong", then back out the fridge through the intake fan. I'll be enriching with co2 via the yeast brew method, I'm not sure how much I should use at this point. The hose from that will merge to the intake and all of it will be run through an inline carbon filter, then back to the box.

The light will be ventillated by 4 cpu fans 2 for both intake and exhaust. They will be drilled and mounted into the back of the box. I might then also have more fans on the other side of the box that will help push the air out, this is all in the glass part by the way. I heard you should only push air not pull though lights so would this work?
The grow box will also have several cpu fans pushing air all around. I'll have thermometers, humidity and ph meters of course.
So here's what I wanted to ask: I'm not sure about nutrients yet. Is there anything specific I should get for Northern Lights or does it matter? Whats your opinion because everyone says something different. I'm considering using club soda or seltzer water too.
Will this set up keep my temperatures where I want them? What about humidity? I dont think I've seen anyone do this before.
Do I have enought light? I was thinking about using flourescents in the chamber for the sides whenever they got big and blocked the top.
How long can I go without ever using fresh air? Can this set up give my plants Co2 poisoning?

Any input is appreciated this is gonna be a sick grow just wait

Alright guys scratch northern lights Im gonna go with chrystal from nirvana.
I picked my nutrients, but is this too much?

The hobbyist bundle from advanced nutrients
http://www.discountadvancednutrients.com/index.php?act=viewProd&productId=252$160
should I get the sensi or connoisseur?
and Bud Candy,
http://www.discountadvancednutrients.com/index.php?act=viewProd&productId=63 $40
I also heard about purple maxx and gravity and want to use those too but will the plant be able to take all of this? Obviously I would ween it on a little slower.
And I was gonna run an autopot set up and I heard lots of nutrients could clog it so is there a way I can prevent that or should I use a dif set up with that many nutes?

subbed + rep

not sure on nutes man thats not my deal, personally i think people spend way too much $$$ on N-P-K when you can get some cheap stuff thats the same as the expensive stuff. i mean nitrogen is nitrogen, there is no brand name and no dollar store nitrogen its all the same :)

like i said i cant really comment as i havent used them before. but if you look at the amount of money your dumping in compared to how much more actual yeild you get not sure if it would be worth it as i grow to save money :)

so heres what I was thinking bout ventilation:
a 270w son agro will mount at the top, under the light will be 2 layers of 1/2" thick tempered glass, with a 1/2" of air between the two. They will seal the light from the grow and there will be 4 cpu fans that are about 40cfm each, 2 of which will sit low enough to cycle air from the buffer layer between the glass. What do yall think about that? I dont expect very much heat.

So for the grow chamber I'm really trying to figure out if I can run a closed system, because I'm using co2. I'll use 2 inline 4" duct fans(about 65-80 cfm each) for intake and exhaust and a 4" carbon filter for scrubbin. They will route thru the wall to a neighboring dresser and loop right back. How can I control heat and humidity? Im not asking for the fundamentals I got that, and no shit itd be easier to run it open that doesnt matter. But this is a small set up and with what I'm doing for the lights and because I have way more airflow than I actually need in the chamber I figure that alone could keep temps where I need them(which would be around 85 for co2 right?). I'll also have 15-20 of those same cpu fans( found em cheap
) place interchangeably along the walls to evenly blow shit around.

Has anybody ever done anything like this? believe me I searched.

I doubt I'll have heat issues but I'd love your input
What Im really worried about is humidity

are you concerned with low or high humidity?

if its high humidity just get some of them silica gel packs that you find in beef jerky bags or shoe boxes, swap em out when they are not working anymore. or you could use a rice sock for humidity but that may get gross after a while depending on how humid it is.

is the second dresse going to be a grow or just a air box? if its just a air box hook up a smalll ac to it , then pull the air going back to your grow cab off the bottom of the box.

sorry for my ghetto paint diagrams, i find it easier sometimes to give a quick drawing of my concept than explain in words and also feel that it helps the other person understand what exatly im talking about.

Here this is my diagram lol. The fans at the top are seperate for the light. The problem with your idea is my second chamber(just for air) isnt very big. plus wouldnt that create too much pressure? if its blowing in from the ac and not leaving it would either have to be a not completelyclosed system or too much pressure me thinks

@skiniti thanks bro I appreciate it.
@matt I havent found an ac unit that is small or cheap enough no. the space is about 16"x24"x"24. Im trying to think of cheaper diy ways of cooling the air within that chamber.

but I think I found my answer guys, liquid cooled light reflector tube.

but fuck paying $300 for that shit I thinks ill make one. Im sure plenty of ppl would like to know how to do that so if I can figure it out I shall post here
