Need HELP Designing my STEALTH Closet Grow Tent!

Well I am about to get the Secret Jardin DarkRoom II Pro 60 - 24 x 24 x 64 Inches in the mail and putting it in my closet (36 x 28 x 66 inches.) I will be getting a carbon filter around the 1st week of flowering most likely. I have a 400w iPower Cool-Tube Ballast (Dimmable) with a 400w MH/HPS bulb. Only running on 50% whole process. Probably 75% the last two weeks of flowering. I have a 4" VenTech Inline Fan (240 cfm). I have 4" Hydrofarm ActiveAir Non-Insulated Air Duct (25 ft). I have a SE Electronic Stepless Controller, AcuRite Temp/RH Monitor, and also will be doing a SCRoG with Dr. Plant Support (2 x 2 feet.)

I will be growing in (2) - 5 gallon Smart Pots.
Medium: 1/2 Fox Farms Ocean Forest, 1/2 Fox Farms Happy Frog.

Any ideas? Suggestions? I would love some sort of design to have ventilation before/after I get carbon filter. I will be using one 4" inline fan & 1 oscillating clip on fan until I can afford another one with the carb filter.

Thanks

This is the plan I have drawn up so far, please correct any mistakes!! INPUT!

So far so good man! - ZTELTHY

Looks good. Get the carbon filter now and put it in front of the light so you dont need another fan. Some strians are very stinky in Veg!

So you guys believe I will only need one fan?? and just a carbfilter?

One is fine in a tent that size. Filter>Sealed Hood>Fan pulling air out>

Now will it be ducting out of the tent > filter > hood > fan out duct out otherside of tent??

You want the air to go through the filter as it exits the tent to kill the smell.

This is almost identical to the build I'm doing so maybe I can learn from you. Any changes in your filter/fan/light setup? FYI - in some of the posts I've read regarding the light/fan order it has been mentioned avoiding putting your fan after your light to avoid drawing the warm air over the fan and shortening the life of the fan.

you want intake by lights
and extake low fresh air dense bud
