    I already have built one for myself with exellent results.
    These pictures show what one looks like after it is finished being built.
    :pimp:

    First, is to purchase the tubs. I use 22gallon rubbermaid tubs. One may choose to use bigger tubs or smaller tubs depending on preference and use. I can flower one decent plant per growbox. Any brand will work, but I chose Rubbermaid because they lay the flattest and sturdiest when topped on one another. My first growbox is made of blue colored tubs spray painted. These tubs are brown. The darker color the better to keep the growbox dark during the 12/12 flowering cycle.
    Each tub cost $7.45 from Wal-Mart for a total of $14.90 before tax.


    While at Wal-Mart I also bought my CFLs; each is 26 actual watts (1700lumens). I will need 6 CFLs (156watts/10,200lumens) and these are the biggest you can fit in 22gallon tubs.
    A 3 pack costs $7.58. I purchased two for $15.16 before tax.


    The next step will be posted very soon...stay tuned!

    This can be fully light proof. Easily could be put in a closet. Left out like a regular dresser or cabinet, no...lol. I sleep with it in my room during veg and it's not too bright. I would have to say I am within 3-4 weeks maybe sooner of harvesting. This is my first grow, but I am checking trichomes daily. Getting cloudy with some clear but still hard to tell. Updated pictures of my grow can be found on my grow thread http://boards.cannabis.com/showthread.php?t=77007, I will use this thread strictly for how to build the growbox. I needed stealth too, which is why I chose CFLs. I was really suprised how big the buds are growing from one plant. There are alot of variables when growing, but just keep reading and reading and reading threads like me and we will grow our own magnificent buds.

    Next step!

    Next, you need the light fixtures. For the 22gal tubs the 18in, 3light fixture from Lowe's is ideal. You need two fixtures one for each side of the box.
    Both fixtures cost me $19.74 before tax.

    The second picture is how the fixture should look before being mounted in the tub. Take off all the white pieces (have to unscrew the 'ground screw' to get the main body off). This will keep every ince of space maximized.

    Now you need to mount the light fixtures in the tub. I used the supplied bolts and grabbed a couple of nuts lying the around the garage to mount the fixture. I used a soldering iron to put holes for the screws to go through. You also need to make a slighty larger hole for the wires to come out of the tub. Feel free to plug the screw and wire holes with caulk or the like to stop any possible smell or light leak.

    You will only need one spare extension cord to wire this box. I used a segment of cord to go from one fixture to the other and then wired the plug in end of the cord from both fixtures but only on one side to make movement of the box easier. I matched white and black together and then the green from extension cord to the ground cable.

    active outtake, passive intake

    I used the soldering iron again to make a hole on top of the box (where the heat is from the lights..duh) for my fan to blow through. A cd was the perfect thing to trace as it was exactly the diameter of the computer fan i will be using.
    Next I used the soldering iron to make a hole for the passive intake.

    The active outtake must be larger than the passive intake or you wil lnot have any 'negative pressure' (airflow) through the box.

    my ratio is about 2 or 3 to 1.

    The grow box has light!

    Now all i need is the fan for on top and caulk to secure the passive intakes.

    When putting in the passive intake be sure to get 90 degree angled PVC elbows then can fit into each other. This is so that the passive intake can be angled in such a way as to not let light escape when it is on.

    I will post more pics when i get this badboy finished and some plants growing inside. I will also post a negative pressure test with a lighter picture.

    I will also give a total cost at the end..i have been saving reciepts (i know, i know...its a paper trail, but its to give people a rough estimate)

    hope everyone enjoys and find something useful from this!:thumbsup:

    I forgot to show everyone what happens when a nice round edge looks appealing to run your finger around!

    Finished

    Now, it's time line the bottom half of the grow box with foil tape.
    This takes a while but it makes it lightproof and reflective.:upsidedow

    Then I caulked in the passive intake on both sides to ensure no airleaks.

    I also caulked the holes the came with the rubbermaid tub just to be sure.:stoned:

    Finished

    Here is the finished product, with no bought active outtake fan on top but a little regular one.:dance:
    One picture is of the growbox in light and another is of it in the dark, it does leak light/air but this can all be easily amended if you apply yourself. For me this is good enough, I can sleep with it in my room at night. :thumbsup:
    The third picture shows air being sucked into the passive intake. With a better fan mounted on top their is more air pressure.:pimp:
    The last picture is of a fly i caught and put into an air tight container i was propping the passive intake on while the caulk dried.:stoned:

    Cost

    I forgot to mention the total cost of this project!:dance:

    I will post the total cost of everything without tax, that way you can just find out your own personal total by adding in your sales tax.:stoned:

    Entire cost is, in three trips to three different stores: $16.34
    $30.06
    + $32.28

    =$78.68:smokin:

    ...for a portable growroom capable of going from seedling to end of flower...:thumbsup:

    I'm not using that table fan anymore...ut uh...I'm using the inline duct fan from the bud dryer box:eek:
    All you do is splice the wires....you match colors mostly:thumbsup:
    Depending on where your growing at just have your 12 hours of darkness during 12/12 be at night like from 9pm-9am or somewhere close:dance:
    I do that with this grow box and it works fine:pimp:
