Help setup my stealth grow cabinet

So I need some help, I already have a 120 grow light, mylar reflective blankets, soil, Personal fan and cabinet.


Now I need to make this stealth, my parents can't know, and it can't smell.


I need someone who knows which is the best odour remover. and perhaps some tips on circulation.


Here is my blueprint:





can anyone recommend where and how to get good air ventilation?

I wouldn't put those fans on the bottom that you have drawn in green. I assume those are intake fans. Just do passive intake by cutting a single hole and have the outtakes fans drawn air through the entire cabinet. If you want it 100% stealth those fans on the bottom will spill light out all over and it will be incredibly noticeable.

It looks like you have 2 fans going in. I would rig them all as out takes on the back side at the rear. Then cut an intake hole out near the bottom at the rear.

It looks like you have enough room to run a single larger fan with a carbon filter, but you would want to have adequate CFM's with the carbon filter hooked up. It would probably be too many CFM's to keep quiet if you go that route.


In regards to the smell, I've seen some grows on here where people place Ona Gel inside the cab and it completely eliminates the odor of one small plant. This seems to depend on the strain and size of the plant though.

The two least smelly strains seems to be white widow and northern lights from what I've read. Other than that, a fruity smelling strain could be strong, but may not be noticeable as a "weed" smell... I'm not sure on that though.


Whatever you do make sure you have plenty of airflow. I learned this this hard way with my grow. I cannot keep the temps under control without loading my PC case up with fans and thus compromising the stealth.

I would try to run 4x80mm at the very least. In regards to stealth a 120mm-140mm is very noticeable. I have a 80mm that runs dead quiet and would assume other models do, so I would stick to that route.

Hope this helps.

2 things... get a cabon filter, and get yourself some ONA.

with the above 2 items you will be golden.

What is ONA gel?

it's a gel that blocks/absorbs the smell, pretty good shit though

Youll need an extraction fan somewhere on top bro...hot air moves up.

If I was you...Id use the two pc fans and put them somwhere above your light... a simple hole in the bottom will attaumaticly pull air in because of negative air pressur and the fact that your cab is small... with the oss fan blowing on your plant, you should be able to keep it cool in there...

Iv got a buddy who says that this ona gel works really great!

and when you look up for fans, get an eye at the noise (db, 10-15 is dead quiet, you can also use 20-25, it s not dead quiet, but still hardly noticeable) and at CFM (cubic feet per minute, look up for ones with 40+).

Would the fans placed here be good?

Also...in my experience, painting the walls flat white will reflect as good as mylar, but be able to reduce heat by 2 to 4 degres also...

What u just did is actually perfect... this way the hot air from the bulb is constantly pushed out... but putting a simple glass just underneat your light, your cab will probably be room temp all the time...

Mesure your dimension and get a glass picture frame the same mesurments... walmart sells 11 by 15 for like 10$...just an idea...with the 2 pc fans like the last drawing will probably do the job...experiment

thank you for the help, now I just need to make the cuts on my wood to start installing the equipment and wait until my seeds arrive.

don't jeopardize the parent's crib.

yes, that is a good airflow, but be sure the fans are good enough to do their job. i personally use the same scheme and it works well, i got 2 cfl's (23w each), and a cabinet just like yours, the temp reaches highest point at 30-31* C.

what kind of fans do you have? if possible can you link to them? thanks.

Also do you use the scrog method?

i just started, 1 week till seed popped, planning to use LST Training), and as fans i use 2x120mm scythe slip stream

and another 2 regular pc fans (unknown name .) blowing straight at plant, for toughening the stem and not letting the heat build up near the plant.
