Stealth grow dresser, 12 23w CFLs, LST + scrog screen, white widdow + sour desiel

it looks like a well thought out (electrically, and structurally), grow box, but for the life of me, i can't figure out where your intake vent (inside the box) and extraction fan are.

not a criticism, just a word to the wise that you probably already know, but in natural convection, heat rises, intake should be at the bottom, heated air extraction should be across the box at the top...

i'm sure they must be there, but i'm too stoned to figure it out...

g' luck...

Thanks for the comment. Both of the fans are on the back door that opens and shuts on hinges. The one on the bottom is the intake, and the one at the top the exhaust. You can see the fans in the photos of it open next to the fan speed controllers, and on the one of the back of the box those things that stick out are the light traps and the fans are behind them.

yeah, i understand that part.. hahaaha i'm not "that" stoned.. but how does the intake fan 'pull' air into the box?? there doesn't appear to be an internal vent from the rear light trap. and how does the exhaust 'pull' the heated air from inside the box??

i just cannot for the life of me visualize where the vents from the light traps are to and from inside the cabinet??? like i said before, this appears pretty well thought out, but from the fotos provided i just can't make out how the air gets from inside the dresser into the light traps...

air exchange is better accomplished with fans pulling air, rather than pushing it, efficiency wise.. plus fighting natural convection seems problematic...

OH i see what you are saying they are 6" fans so directly behind them i used my jigsaw and cut 5.75" circles, just enough room to mount them with 4 3" long screws but still allow for almost full airflow. Then on the exterior it was just two holes exposing the fans inside and i then used liquid nails and some MDF and built light traps that have slits cut on the face on the opposite side of the hole exposing the fan for a little box that lets air flow but blocks almost all of the light. At night there is a very dim glow emitted from the two slits where the air goes in and out, holding paper up to the slits you can see it sucking or blowing.

everything look all nice and neat very well thought out i like it

Thanks alot man i spent a lot of time making sure it was well built so that i had no excuses for any problems i might have with my plants. The seeds have now germinated and got planted this morning, i will update with more photos as soon as the plants break the surface of the soil.

Looks good, but where is your light timer? I notice the powerstrip, those are GARBAGE...i used one for about 2 days before i took it back to the store. You cannot program it for 12/12 cycle, it is not to be trusted, please do yourself a favor and buy a timer!!!!!

The light timer is the power strip at the bottom of the box with 8 outlets. 4 of the outlets are set on the built in timer ( have the 4 power strips the lights are on plugged in there) and 4 of the outlets are always on (for the intake and exhaust). What didnt you like about the timer power strip exactly? i am open to replacing it as i do not want any issues with my plants i am just confused as to what is wrong with it i have yet to try the 12/12 cycle like you said on the timer but the 18/6 cycle tests worked just fine. I do not know a lot about timers i mostly just built this box from online reviews and taking parts i liked from others builds on RUI and just smashing it all into a small craigslist dresser.

I wasn't able to get the timer to work, then 1 day into figuring it out the clock kept on resetting back to 1200 and flashed..it did this about 3 times and you know how long it takes to get that thing programmed..its just not worth the effort... Get yourself a heavy duty mechanical or digtal timer and plug your extension cord into it with all of your lights, JMO i think that you would be better off and not have any worries!

The timer was a bitch to program, i will give you that, and every time that i unplug the box to move it to a different room i am stuck reprogramming the time of day on the timer. If i do have any problems with the actual functioning of this timer i will be replacing it but until then i am going to leave it. Do you have any suggestions on timers that are of nicer quality? brands or specific functions to look for would be helpful because i am designing a similar flowering dresser that will need a timer also.

You dont have to spend a ton on a timer for a single light, just a basic $10-20 dual 3 pronged outlet will work for you needs, brands..none specifically.

i like your design very smart and looks awesome!! i want to make one just like it haha

If you want a grow dresser i really would recommend building your own like i did, it saves you tons of money over buying a pre-fab one and they are fun to make. I could walk you through it if you were serious about it.

yeah i like building shit my own so i can make it exactly like i want it to be
i would be serious if i could find a dresser or something that is cheap and would make a good box. i went to salvation army the other day and every good cabinet/dresser was part of a damn set

I bought mine on craigslist for 10$. i would recommend getting one a little larger than the one that i did so you have more grow height, the only reason i built such a small one is i plan to use this one as a veg box and build a 6 drawer tall dresser into a flowering. Good luck picking out a dresser make sure you get one you like because there is no turning back once you start!

I recommend trying to find an armoire, they are wider and taller!

Wow It looks really really good.

Was wondering where your intake and outtake points are? Other than that it looks great. Smart work on some points, and its your first grow, I had to redesign mine at least a few times before getting to somewhere like yours. Also with your constraints I would have suggested the lowryder strains, but its just as fine to let it veg until its 1inch then flowering.

sub'd, that dresser looks clean..plants should dig it for sure.

As far as you having to redesign yours a few times, i had to totally tear this apart and start over twice perfecting things and the back door on the box with the intake and exhaust i had to rebuild 3 times to get it just the way that i wanted. And you are not the first person to be confused by my intake and exhaust so i took so more detailed photos to clear things up hope this helps. If you look at the photo behind the 6" fan there are 5.75" holes into the light traps so that air can flow freely but the bends in the light trap stops the light from escaping. before those boxes on the outside of the back door there were just 2 5.75" holes exposing the fans to the outside. I also took a side shot of the back door so you can see how the light traps line up with the fans. ( ill add these photos to my original post as well )
