Well as the topic states this is speaker box that ive made from scratch, I thought up of the most stealthiest cabinet i can think about and i put it all together. The cabinet measures in at 40" in height, 20" wide & 20" in length, I am going to be using a 250watt Metal Halide for veg with my ballast outside the box, As seen from the back of the speaker box i have Two 100mm 4"(inch) plastic port holes which i am using for the extraction of the air, what would you gents suggest? > ( A ) I cooltube the light with one extractor fan pulling the air out to the one port THEN using the other port beside it with a mounted home made carbon filter extracting out ?, however i do have One 75mm port infront of the box on the top at the same height as the two ports extracting which i was thinking of using but at the same time thinking of closing. ( B ) leave the cooltube out, Use my reflector & mounting that i have, mount two carbon filters on both ports extracting, perhaps even extract with the 75mm port too ?

Excuse me for rushing into these questions but im sure ventilation in a speaker box like this is going to be my main concern and anybody that would be reading and seeing this, correct ?

Let me move onto the pictures & do the explaining, i think throwing out everything at once on the post then taking a look at the pictures makes things a lil confusing.


Sisalation(reflecive stuff) has been attached to only two sides, still busy with the rest.

This is a plain picture without the grilles attached, it looks a little messy on the top but this is because i havent screwed the top on properly due to the light not being put on yet, plastic corners like the bottom will be attached on the 4 corners on top aswell.

This shows hows the finish look will be, note i havent fixed the grills on yet, i am making a plan to make it look like there's a speaker behind there & ive just come up with a plan about 3 hours ago : ) new pics to come soon!

Getting to the intake ports, you will see i have placed them nearly in the middle of the box in front, these are also 4" ports which i will be ducting a little so i can curve a 90 angle for a light trap. On the other hand, i would like to leave the fan part to you professionals, what would you gents suggest for that ?

As seen from these pictures you can see the front and the back, maybe you wondering why's there's nothing attached to the back except the bottom piece but i have attached the picture of what i explained concerning the extraction from the two 4" ports which are placed at the back on the top as seen below.

Here's a close up of the two 4" port holes that fit onto the back, This is how it looks from the inside.

Outside Close up

This is the lighting fixture as described and seen, 250 watt Mh/hps switchable ballast with my reflector and the e40 bulb holder mounting.
I will be placing the ballast in a metal box outside of the speaker box.
I know this is a quite a big light for such a space but im planning on making it work, i would really appreciate help from you guys on this!

Yesterday i attached the lighting fixture with the 250 watt metal halide, i drilled to holes on the underside of the top panel of the speaker and placed the mounting with the wire going outside the box leading to the ballast, this was just a little test i gave a shot, yes this might sound odd but after i placed the light i put on the middle door temporarily then i put on the panel as i showed with the two 4" ports on top, so basically it looked like it was closed up like it would be if it was finished, i have a zalman pc fan about 80 cfm's & another coolermaster fan at about 50 cfm's i left the light on for about 4 hours with the fans running, no intake fans just two extake like i explained, 4 hours later i felt the box and temps seemed to be at about 30 - 35 degrees celsius i think in Fahrenheit its about 90 maybe 100 ? So what you guys think? maybe get another 80 cfm extracting and putting two intakes would sort this out ? Im no expert on fans and all but im just trying to give an idea. i know you guys can help me on this, i aint doubting it !

This is the 80 cfm computer fan below.

Down below i attached a picture of my other growing media, Bio-Bizz Grow , Bio-Bizz Fish Mix, Forgot to put the picture of my Diamond Nectar, Bat Guano, Syringe for nutes and 4 small pots even though i am considering growing 1 blue cheese feminized seed that i have from big buddha.

and with the last pic, my vermiculate & i hope im correct "Coco peat bricks".

This has been quite a post for me, i hope i have explained everything in enough detail, i will really appreciate any help that you guys can offer, if there's anything ive said thats stupid or out of line, even if it doesnt make sense please let me know about it, thank you! happy smoking it up guys peace out !:smokin:
 
Thanx man, thats what im planning on doing, i think putting two of those zalmans shud do the trick, im also in winter at the moment so my room stays quite freezing cold at times unless i got my heater on, so i guess for now while im a lil low on cash im gonna set it up like it is, later on when summer comes il think about cooltubing etc putting stronger fans, what do u think i shud do with the carbon filter? i am unsure of this as im thinking it might limit airflow for the heat of the light to go out ? on the other hand what do u think of using those gels that smell ur room up? getting sum automatic air freshners etc ? Help will be appreciated! thanx for the reply though man
 
yes zalmans are fine, i have a single nexus silent fan as my intake, whisper quiet and cant be heard over the sound of the water dripper. I used a small carbon filter at the very top of the grow room, which is vented via a small 60cfm extractor unit. it keeps the smell down, but im only in very early flower. ive never tried the gels etc, just because i keep all chemicals away from my plant, i dont even use polish or any other shit in that room. the carbon filter is doing its job regarding the smell and it also removes quite alot of heat from the room. like is said earlier the main drop in temps i noticed was when i added the cool air intake, and opened a window, lol
 
I do like this grow box. If you do a good job light leaking it, you will have made it very stealth. (just worry about noise from fans and smell when you get to flowering)
:cool:
 
Shot guys! im loving the feedback no doubt, Ezygee tell me man are u using a 250 watt aswell ? how big is ur space ? looks like you aint using much ventilation and its working perfectly for you :) i know what u mean with chemicals etc, i dont plan on using these sprays or gels to eliminate odour, i know that carbon filters work perfectly, i was thinking of using ducting lets say about 40cm/16 inches, now what i want to do is attach 2 carbon filters DIY made on the two 4" inch ports that extract(Note:the ports at the top) attach 2 axial/computer fans @ 90cfm's each to both of them, lets say right up against the carbon filters, close up right? then take the ductings across to the other end facing them down so they can extract the heat, now what im thinking is attaching another two computer fans to the ends of the ducting, what do you guys think? im not sure if the airflow will be okay like this? BUT this shud insulate the sound level? help me if im wrong plzzz! it will for sure block any light though. Looking at the bottom intake ill be using two 50-60 cfm computer fans pushing the fresh air inside, this will be shortly ducted & painted black inside, i will be curving the ducts slightly aswell to block any light, O and Lighter as for the light leaking that u mentioned, if what i just stated above works, what do u think? i rate its gonna be tops, i sealed my box very tightly note the carpet sticking out on the insides, i joined the chipboard knowing there's no leaks there. Although YES u correct but im making a plan so that no light leaks through my air port holes!
 
600W HPS, in a 1m x 1m x2m grow tent. i wouldnt say its working perfectly yet, i certainly need to adjust the extraction unit, it isnt venting much heat at the moment. sorry m8 cant help much on the carbon filter issue as im just a beginner, but the top back air hole in the speaker, looks just right for adding venting, btw, you mentioned a diy filter, do you have any further info on this. to cover the noise you could get another speaker and pump up the volume..lol
 
1 carbon filter should be enough. (your only going to get max 2 plants in there, realistically 1)

duct tape is your friend for light leaks.

and your exhaust, the fans sound fine, its a small space, not a whole lot of ventialtion is needed (just enough to control temps) so 2 fans sound fine (although i would make one for incoming air and the other for ehuast). make sure to have a circulating fan (fan inside box).

And the ducting, your going to want to pull the air out of the box as close as you can get to that 250w (where the heat is) so pointing that ducting down is probably not the best, point it up instead (room permitting)

Also, the carbon filter is going to take up too much room inside the box, is there a way you can mount it on the side of the box and then add some type of covering for it with a whole at the bottom (for disguise)

hmmmm, maybe an extra "tweeter" box or amp.

Last thing, did you make the top of the box reflective? If so ditch the reflector for the bulb (maybe you were planning on doing this already)
 
Ezygee if i can say, ur box is like exactly half the size of mine ? 600 watt hps in there, seems like it will be okay if u venting it correctly, dont think u hitting up alot of stealth though right ? if not, im sure venting it in a way aint going to be a problem. thanx for that input lighter, im agreeing with you, yes 1 carbon filter sounds more than enough, like i said i was planning on making a small carbon filter, one inside a smallish tupperware container that i can basically stick on to the one extake at the top, then i have the other extake which 100mm the same as the one i want to attach my carbon filter too, now you rate i just use that one to extract the heat of the light ? Maybe a 150 cfm axial wud do the trick? then i still have the 75mm port which i cud use a 8cm pc fan to extract the light heat aswell ? depending on how big my carbon filter is i will have to see what im going to be working with, if it sacrifices to much space then yeah ur idea of using an amp to disguise it sounds perfect too :) i havent put the reflective stuff at the top yet but i am going to do so, do you think not using the reflector will be okay though? One more thing, im a lil confused about the carbon filter and extracting the heat out, im a little worried that the heat extraction for the light is going to extract the odour ? or do u recommend ducting the carbon filter vent closer to the plant for maximum odour extraction ?
 
well, the reflector is up to you. i would leave it out for room sake if you have reflective lining on the top (which takes up no space). and chances are, the reflector would be made of a metal with another lining in the inside. well that metal exterior on the top loves to hold heat (has to do with the ability for metals to abstract electrons into their valence shell)

And the exhaust...
you already have holes made but here would be my setup which you can modify to suit your needs.

4" whole at the bottom with pc fan blowing into the box (intake) (no ducting required)
near the top of the box by the light, have another 4" hole with pc fan blowing into ducting that leads into carbon filter. Now, since I would be trying to push air into a carbon filter with only a pc fan, i would add another pc fan on the exit stream of the carbon filter to ensure air flow.
 
Allright if i leave the reflector out its no problem, the problem is lighter lol ive already made this box, how would you expect me to now close those holes and make other ones ? this would completely screw up the box, i have carpet stuck to it with spray glue, how do u think i must do this ? scrap my box and make another ? why not just duct my intake to the bottom of the box ? i already have two 4" ports at the top of the box by the light & 1 port next to them that is 3"'s ! thank you for your help man but im really confused, i have the holes which u are stating i cant just go drill more lol
 
o ok sorry man, just got confused about it but in anycase i cud just duct the intake to the bottom though & then the top i cud duct with a pc fan at one end and then another at the end by the port hole with my carbon filter attached ? do u know how the airflow would be with two pc fans in a duct ? Thanx for the help man, apologies for the misunderstanding
 
dont duct the intake to the bottom, your going to want to save as much room as you can, so use a 4" turn down (commonly used for a dryer exhaust, ask the guy at Lowes or Home Depot)

the only air flow you need to be worried about is around that carbon filter. your going to need as much power as you can to push air through it. so, put a small fan before and after it... and your just going to have to experiment with it, if there is no air flowing being pulled from the box (put your hand over the initial hole leading to exhaust duct and see if it sucks on it a little) then your going to need to up the type of fans your using.

im stealthed up as much as the only light leak i get is when the bottom flaps on the grow tent are open, but it looks like i just have a normal night lamp on, i have made a visqueen cover for the inside of my window, but i currently have two curtains covering it, waiting to get some spare cash, then i will buy a cheap wooden blind for the window, then i can use the visqueen cover to block all light when i need to work on the plant. i still need to sort out the temps 39C is way too high..lol
 
Yeah Lighter 4sure, 100% correct, sacrificing space is sacrificing more harvest that i can get, i want to stick to that, Just gotta make sure the light dont leak. "Turn Down" do you mean something more or less like this its a pvc wall cowl >
or something similar to a pvc elbow ?

Sorry man im from RSA so things are diff here :/ people dont know alot at the hardware store & the variety of products in hardware stores dont range a long way, so i have to go to the places which specialise in these things for example the place that sells the wall cowls etc.
OK so far thats for the intake, now the extake- Lighter you explained you would use one hole to extake with a carbon filter, so one fan before and one after the filter, you dont think i shud use both holes with a carbon filter each? then ill be using 4 for fans for extake, im going to try it anyway on one of them just to see how it works? Gonna do a search aswell to see if i can find anything similar, Ive thought about it but always unsure of the air pressure, how much air does the filter block etc... otherwise if its extracting air, filtering smell & blocking light, its gonna be one sick unit! Thanx again for the input bud ! i appreciate it !
 
the pvc wall cowl is what i meant, but either will work. I am not sure which is cheaper.

two carbon filters is unnecessary for only 1-2 plants. stick with one. just remember, make a miniature carbon filter since it is a "micro grow"

you might be able to skip on making a carbon filter and use some ONA pro gel (there is one other scent also) and it will hide the smell for a few weeks
 
Aight man, thanx alot for that help : ) i was just confused on the part about having 1 carbon filter and then the other air port with none, wouldnt that force more odour out of the Port that has the most ventilation? so you suggested i should use the ONA progel i was thinking of that since i aint going too big man should work? one more thing Lighter how do you i should Lighttrap the top though ? those ports are close to the light or lets say nearest, u think a pvc cowl or pvc elbow will do the trick with black paint inside ?
 
oh i didnt even think of that, some people use air filters and cut them and make that to control a light leak, otherwise, the cowl will still let lots of light out, especially if your lights are on if the room is dark. so, go with an air filter, and cut it to size 4"

so, if you are in agreement to do that, go ahead and scrap the carbon filter idea and use just some ona pro gel instead. you will still need one exhaust fan either before or after that air filter. (just the kind most a/c's use)

use the cowl for the intake like said before, and go ahead and paint the inside black thats a good idea. (it will be pointing down away from light and black will be inside so SOME light will be blocked, but since its so reflective in there it might not help a whole lot and you might end up using another piece of air filter to light leak that hole as well.
