What you guys think of this setup?

Hello all first time here. I have been searching the forums a lot and got a lot of info. Here is what I am going to be running. I am putting together a wardobe closet. It measures 71" tall by 48" long and 20" depth. Its 133cf. I will run a 6" inline fan to the roof of this closet. I will have one 3" passive intake on bottom of the closet with a filter (for dust and so on).
400w MH/HPS (HTG) w/ this reflector (sealed hood):

OR do you guys think i need to go with a cool tube? Heat is a issue where i live and it can get up to 115 degrees outside in summer.

450cfm Inline fan:

Carbon Filter:

The exhuast will run like this: ==Hood==carbon filter==fan==roof.

I am looking to grow 4-5 plants in here. I will also be using mylar, a couple os fans, as well as a humidafier when needed (we get very dry heat here)

What do you guys think. Will be using FFOF soil with the 3 FF nuts. Anything i need to change in my setup? Thanks so much for looking.

looks good, I would change to a much larger intake, at least 6" diameter or you need 3-3" holes. run your filter, hood, fan, roof. your way wont work. all else looks good.

I have read so many people saying bigger hole then the exh, then other people say smaller hole. Why wont hood carbon filter fan work? The hood i sealed so on one end it would be pulling in the air from room, thru the hood into filter and fan. I didnt mean the hood is completely sealed, just the glass on bottom so its sealed from the light heat ray but open on one end to pull air from the room thru the light and thru carbon filter

Nevermind about the carbon filter placement. I see why it wouldnt work lol i always thought they have flanges one both sides. Ok but intake size would i really need to grow 3 3" holes to make it passive?

Depends on what speed your fan is set to. If you only have 1 3" intake hole, and 450 CFM or air getting sucked out, it's going to put quite a load on your fan because there wont be enough air to suck. Also your closet is going to start whistling (like a wind storm).

Yea i wont have it pumped up all the way, so ill make 2 3" holes and see how the closet does from there before i drill 3 of em

Sounds good man. Let us know how it works out.

Yea ill make a log of the build. Should i go with a cooltube sense heat is a issue and anything i can get that will help is worth it or the air cooled sealed hook for better light. I herd the cooltubes no distribute light well

2-3" holes equals a total of 6"x3" your fan is 6"x6"..... 2 is not enough shit add 5 you wont be pissed you did

For the intake you want 2/3 of the exhaust CFM.

The exhaust cfm is 450cfm my closet is 133cf.

So probably 375CFM after filter, and you'll probably want to turn it down to 250 (exchange air 2x/min) Should be good with 3 - 3" holes.

Thanks so much for info .Also should I go with the cooltube sense it gets hot as shit here or just go with that air cooled hood> i herd the cooltubes dont distrubte light well

Cooltube's, if left the same distance away from plants as a hood, will have a little less penetration. But, because it's a cooltube, you can move the light within inches of the plants, giving the same if not more light penetration than an air cooled hood. With that size fan you should definitely get a cooltube (or make one; DIY).

Will do, thank you so much for the help

No problem man

most air cooled hoods work great, some cool better and some distribute light better, do some research and make the best choice.
