Yo, I have a thread on here somewhere that I built a PC case, temps are an issue always, best way is to cycle the air from the top out and have your intake be passive and lower in the case. My case has a fan in the back up top and a fan in the front in the bottom. I originally tried to do something similar to your ducting work with carbon filter. dont bother, get some ona gel or block and that will cover the smell just fine, I just used an ona block to cover the smell of a nearly full box for flowering that measured 2ftX2ft. Now for your light traps get some cardboard or poster board, if you get poster board get black, and if you get cardboard get flat black spray paint as well, the black helps lower the reflectivity of any surface its put on, less reflectivity, less light.
the light trap is a simple design and simple concept as well. I dont have this part on my thread(havent done it for my PC case, just the flower box, but same concept) but itll still work. just imagine your case is 20inches tall, and 10 wide. cut 2-5 15TallX5Wide pices of material and off-set them so that one goes the bottom 15 inches, and the next goes the top 15, the next the bottom 15, and so on... obviously use more material and tape/glue to make a box around the 15 inch pieces, just make sure the one closest to the box is at the top, so you get the hot air out first. if the exhaust fan is at the bottom make the light trap on the inside and have the side closest to the fan be open at the bottom and the other side be open at the top, again to take out hot air first.

for yours dont listen to the numbers i tagged in there, make the measurements fit your grow space. this is just what is going to work for my case and is already working for my flower box.

Hope this helps

What do you mean offset? I can't imagine your design. Put one bottom 15 then top 15 then bottom 15? I don't know what you mean.

it is kind of confusing
for a light trap just use a small box with place top of box against fan with side cut out
light doesnt make bends

So should the hole where the air will be going through to the fan be at the top near the fan where the heat is pooling or near the bottom of the light trap? I am concerned that the light will have a chance to make it through an open angle. I'll need to create a light trap for the opening as well

and for intake u want it blowing out the open end at top for intake sucking in from bottom

btw i didnt do that drawing a member here did i just pasted it

So I should have it fitted over the inside of the exhaust in the case with the open side facing the bulbs? And then with the intake you are saying I should have the open end blowing air upwards? Or downwards? I thought you want oxygen blowing towards the roots?

I plan on running to target in a little bit hoping you can get back to me before then.

Can't see it but I took out a screen that was cutting air flow in there and instead put a layer of carbon filtering on those 2 screened sections where the exhaust is housed.


The top exhaust without the housing.


Inside with all fans in view.


Front without the housing piece.

Well since I've put the filter in their the air isn't being reflected back into the box or having a hard time to move through and instead the heat is staying in the top housing and has no where to go but up. I also took the 26w/100w equiv 2700k bulb out to lower heat. Sitting on about 2900 lumens in there right now. I read you need atleast 3000 per sqr ft though. If I took out the filter the temps inside would probably be between 86 and 89. The AC is blowing in the house right now so temps have been sitting at 80 for the past few hours.

Yeah yeah I know, honestly if I had a larger space I would have gotten an inline fan with a nice carbon filter attached and ducting with better light. I was lured in by the DIY aspect of it gutting and putting it together. I could have opted for a larger one but its the least conspicuous in my house hold especially since I am already know for smoking weed as well as majoring in something with computers. So its easy to say I have another computer.

The first pic of the housing being held up is where the filter is in. You can't tell. And its easy to put in and remove because the screen thats holding it on has bendable parts that come through the housing and are bent to stay in place. I have it on both of the screen so the air pools in there. The 80 is the good temp? I think my eldest seedling was suffering heat stress yesterday. It looked like it stopped growing and was closing. After temps went down and after watering it opened up again and is growing. The youngest is the biggest one though now.

Nooo its filtering air coming out. Lol the housing for the top, the top is where the exhaust is...the front is the intake. No filter. Well I am gonna run over to target and get some cardboard cause I can't find anything in my house thats not being used.
