    Hey all. I tried searching but came up with handfuls of random threads along similar subjects.

    Can anyone link or recommend some threads of successful grow boxes? Ill be using a 400 watt hps. I am sure it has been done a million times.

    Thank you for the help.

    Damn.. Really? 52 views and not a reply??

    Well, maybe I should add some more info...

    I have built a 4.5' x 4x5' platform and have started to frame up 6.5' walls. I originally thought it would be good to use a Secret Jardin tent, but due to cold ambient temp in my room I have decided to go this route. My questions are specficly regarding how do I make/seal my door. and lay out my ventilation system.

    Help a kid out.

    I have a box thats basically the same size as what you describing except my total height is 8' and im also using a 400w HPS/MH lighting system. Once you get your box sealed up the heat from your light alone will keep the box at a good temp. probably around 75-85. Make sure what ever you put up for your walls can be covered in some sort of reflective material (mylar, emergency blankets, etc...) so you can get all available light back to your plants and to growth at the bottom. Id def. advise getting some sort of ventilation system to remove smell/heat/humidity. On my box I cut a air out take hole in the top and a air intake hole in the bottom. I went to www.htgsupply.com and bought a 8" inline duct fan 300cfm $29.95 and ran one end of my flexible ducting to my chimney and the other end of my flex. ducting to the hole I cut in the top of my box. As far as the door goes you can get a reflective/sliver coat tarp (off internet or grow store) that has a zipper in it, so you can attach this tarp w/ the reflective side facing your plants and w/ the zipper running down the midde and now you have a way to get in & out of your box. Also another way of doing it and this is the way i did mine is to build a light wooden frame with cardboard or construction board stapled to it. Then attach the mylar or whatever your using to the inside surface facing your plants. Make sure you make your frame the same size as your box to it fits right then I just added acouple hing hooks on the top right & top left (like what goes on a gate or back porch screen door) and that what holds your frame/wall to your box and when you need to get in there, you just un-hook your hooks and move your door to the side.

    I two boxes 4x4x6.5ft tall. I ended up buying the black out fabric from HTG (great stuff) Its heavy duty and a great reflector. Anyways for the door i just used velcro make sure you get the industrial strength stuff, my lowes had it. the velcro is strongg and if you cut your fabric right you'll have no leaks. I would recomend using something other than wood. I used wood and regret it. Once you got that thing built its heavy and hard to modify. I've seen lots of threads on here where people build there frame out of pvc pipe. if i was too do this again i would rather go that route. good luck

    Oh yea you going to need a air cooled hood too. Them 400s are pretty hot if you get an air cooled hood you'll be able to move the light A LOT close to your plants, get a bigger harvest, and will be able to battle and high temp issues that arise more confidently.

    I built a 2x3x7 box for my 400w, and I'm loving it. I made it out of 2x2 sticker boards with 3/4 inch plywood skin - it's definitely a heavy beast, but I didn't want to worry about things I mount to the sides coming loose.

    I made doors out of 3/4 MDF, just two big doors that open in the middle like a wardrobe, which are weatherstripped to block light. I painted it to match my furniture and used similar hardware an it blends in really well, people have not known what it was even when I didn't have a light trap on the outlet and HPS glow was coming out the top.

    Inside it is painted flat white, and has a 6 inch inline pulling through a carbon filter and 6 inch air cooled hood.

    If you have to use wood. Get the smallest you can build with.
    1x2s and 1x1s. Use Brackets and Angles to support your frame.

    Don't forget air intake. Sounds like you have a good idea.
    Using grow tents as reference should help a great deal.

    The Black and white poly (Reflective) will be more efficient for walls and top. It is much easier to manipulate. (Hydro store)
    Using the B&W will save tons of time with cutting/fitting walls. It too can be attached with velcro.

    There is a Plastic Velcro. Perfect for holding just about anything. I can not find it in my little districts HomeDepot. :(
    It works like legos!

    I see the most 2 important things as
    #1 HEAT Removal. (how fast can you get it out)
    #2 Max Height. (max height of plants?)

    I almost went with a wood cabinet in my closet.
    Weight, Ease of Tear down, heat, power tools running in apartment, there were a lot of fears, that kept me from firing the lights.

    I found a tent, cheap, local, easy to set up, near light proof, Saved time, money, and sanity.

    There is a ton of help here.

    Tent growing is so much easier if you can do it.

    Building a wood frame for your growing hobbies is pretty easy. Mine is 6.5ft x5ft x 4ft and I use a single 600 watt HPS in a cooling tube. I can grow 4 big girls(without topping or tie-down) and 6 with tie-down. I assembled all materials into two complete pieces and then fit the two pieces together. I used 2x4 for frame work to hold excessive amounts of weight if needed. I then enclosed the frame by tacking up 1/4 thick wood board and attached wheels to the bottom for easy moving. I then lined the interior with mylar. I also angled the top-side of enclosure to reflect light better downwards. Then I placed rubber matting on the floor to trap any soil,
    hair, debris, etc.

    I placed enclosure under a ceiling fan and placed a turbine air circulater ontop of the frame blowing cool air into the shack. I ran ducting from the room's natural A.C. vent and placed an inline powerbooster on both ends of intake. The exhaust was ran through the bedroom wall blowing into hallway where my home A.C. exhaust sucks it all up and out! Both the intake and exhaust are attached to the cooltube to keep any excess heat from escaping. For the door I just left a walk-through and cover it with plastic sheeting

    DO DRY RUNS TO WORK OUT ALL OF THE KINKS. IT WILL NOT BE PERFECT. PERFECTION IS ONLY A GOAL TO WORK TOWARD.

    Try to maintain 75-81 best you can. Good luck. Check out the pics::weed:

    I was wondering how to make my own wooden grow box and make it look like a plane piece of furniture in my living room of my apartment and I know how to put a carbon filter with ducting but also making it quiet with music sound foam but I dont know what to use as far as puting it together with wood glue and caulk. but also cuz like I know how to keep the sound low and also have fans and stuff. I might also add a muffler for the carbon filter as extra sound proof. But I plan on making it look as natural as possible for a piece of furniture so if they did maintenance checks then theyd just see it as a cabinet and cords coming from the back but thatd be it so theyd think I have a tv or something in there.
