Marijuana Stealth Grow Box #2
#8005414 - 02/10/08 04:50 PM (15 years, 11 months ago) |

here's the floor plan so far...

...the smaller area marked off by the dots it going to be the space i use for ventilation(a series of vents that keeps light from escaping). the actual grow space will be 18" x 18".
i have a 150 watt HPS that is already wired up with a remote ballast. that would be 66.6 watts per sq foot. the light will hang by chain and will be able to move up and down by hanging it from different links in the chain.
i was planning on growing Low Ryder, but i've read that regenerating them with seeds will give a person larger plants. so i need enough room for an average sized small plant..
how tall should i make this box?

change of plans...im think im going to go with 2' x 2' of growing area and just use a 250 watt HPS. make it 5' tall. but the box will actually be 3' wide, then ill leave that extra foot(which will be 2' x 1' x 5' high) for the ventilation.

how many plants do you think i could fit in there? what about low ryder plants? any suggestions?

I've been thinking about a situation exactly like this recently. For research purposes....
you can save a little room inside your grow cabinet by putting all your filters and fans out the back and having nothing but the light (and attached ducting) inside. Of course, if stealth is your aim, that probably won't be the best choice because of noise concerns.
Have you seen this link yet? probably the best stealth/micro grow I've ever seen; MOD EDIT: no non sponsor links (note: I apologize if the above link is breaking any rules... I wasn't sure....)

Oh an also, if you're doing DWC with a 5' tall closet I don't think you need to do lowryder. Just put clones from good genetics directly into flowering (assuming a mother plant is even an option... if you're doing a stealth grow it probably isn't) and you'll end up with short plants crankin' out dank nugs.

Heya,
In 2'x 2' you'll easily house six or even 9 small plants or two pinched big plants I'd make it a foot or two higher if possible to be able to grow taller plants... Gotta remember that 250W HPS uses around a foot vertical space itself and another below it to keep the plants from frying! I have a space around the similar to yours but about 7 foot tall and currently having 2 plants which take all the 2' x 2' space, but previously had 6 plants in a bit narrower 2' x 1,5' space. I hope I ain't mixing your american units 
For strains I would go for something else than Lowryder (potency is decent but yields are not). If you can get hold of some clones I'd go for them. Otherwise find some nice shorter (Indica?) strains to grow. I myself am growing Euforia from DP which is great for spaces like mine (or yours) as it grows ALOT of branches (even without pinching the top shoot) instead of growing heavily lenght.. It's interesing at least, in my opinion 
Hope this helps

Hey Gilrand, What about shorter plants? If you just topped them and then tied them down Scrog style couldn't you get a nice 3-4 plant system only about 4-5 feet tall? vertical space is an issue of sorts in my case (not sure about the OP), so keeping the cabinet under 5 feet is somewhat important.
The cab I posted originally was only 3 feet tall, but I'm guessing that's a master grower who's able to train his plants that style. Let me know if you'd like me to PM you the link so you can check it out.

Hey hey,
Sure, in my opinion scrogging is much better and more efficient way (easy to use whole space of the grow"room", lighting is scatters evenly on colas, etc) to do stealth grows than just choosing the easiest Lowryder (which can be grown ever in computer casing). It needs a bit more attention but usually thats not a problem as at least I like to keep close eye on my plants
Some strains are more well suited to scrogging than others but generally its not so strict. I would think that it wouldn't be so wise to choose some crazy growing sativas in vertically such restricted space 
And yeah, I'd like to see that page so PM me if you can

if youre already looking at lowryder, you might want to consider lowryder hybrids instead
search up lowlife seeds and mdanzig seeds, theyre two breeders of small autos with abut the same stature, but much better smoke, in general under ideal conditions, they yeild 10g to an ounce
lowlife has ak47, white russian, and hindu kush genetics that he has the autoflowering genes stabilized in, also has f1's of the aforementioned, but unless you want diversity id go with the straight ones, cause they breed true, and you need to ake seeds with autoflowers also has something lovingly called "clusterfucks" which basically he put a bunch of random af strains in a room and grew seed from them for several generations
mdanzig has master kush, powerstout (which was an indica bag seed), and bluestreak, which is master kush as the base for the af gene and then crossed with dj shorts blueberry
hope i didnt sound too much like an advertisement  autoflowers are something ive been looking into for myself, and ive done quite a bit of research on them and these are just the two main full autoflower breeders i know

the first box i made(which was about 3' tall, like yours), i made it so that the air vented out of the back, but i didn't like it because i had to keep the box a distance from the wall and i felt it wasn't as stealth. in the new design, im planning on having that metal tubing stuff wrap around as much as i can(so light wont get out) with metal filters on the side of the box.
i only want one grow box, so clones isn't an option...unless it would be possible to maybe grow 4 tall plants, start flowering, then clone the females....? i haven't grown yet, but i've read a bit.
edit: PM me that link.

i was thinking about making it a foot taller...so, ill go with 6' in height. when you say 6-9 small plants, do you mean Low Ryder strain, or any strain? it would be nice to able to grow other strains.
does the 250 watt HPS have to stay a full foot away from the tops of the plants?
would i be able to use the 150 watt HPS for anything? i was thinking of maybe putting it in between the plants when they are flowering....?

Heya,
With small plants I didn't mean any specific strain, just untopped plants with short vegging that don't take too much space horiontally.. I agree with Zinglons Acolyte that if you want to try lowryder get hybrids as the original lowryder strain has alot of minifenos with plants as small as 4 inch tall when mature This is one of mine with height less than 6 inches:

You need somekind of cooltube / coolshade to be able to keep 250W HPS closer than a foot from the plants. I have a coolshade and keep it about ½ - 1 foot from the tops. You can use the 150W one as an extra light, but gotta remember than HPS lights create large amount of heat so you'd have to insulate it somehow so the plants won't burn if you put the light between them

how exactly does a carbon scrubber work? is it basically a fan that sucks air through a tube, and filter-carbon-filter inside of the tube? would that cause a computer fan to burn out or is a special fan needed?
could i have a carbon scrubber suck air out of the grow area and into another area within my box, and have that air pushed(by the carbon scrubber fan) out through vents? im trying to trap light.
for my ventilation, im planning on having two separate areas, one for intake, one for outtake, all inside the box, and that both trap light.
here's a quick picture of what i mean...

so how do i calculate how much air i need to pump out of the box? it'll be 24 cubic feet. would one 92mm fan that's rated "Airflow: 48.0 CFM" be okay? i remember on overgrow.com, they said i would need more for the smaller box i built. if the fan(s) is/are used with a carbon scrubber, will it/they still remove the same amount of air?

CFM= cubic feet per minute
48 cfm shuold be plenty for that, as that means that the air will be replaced twice a minute for such a small cab u dont really even need that much airflow, 10 cfm + yeast co2 would prolly be plenty enough

what about with a carbon scrubber? would that slow down the air flow from a specific CFM fan or would it still be the same? would having more air flow be bad in any way? thanks.

along the lines of positively pressurized systems, computer fans for inrake and a passive exhaust carbon scrubber exhaust might work
like, put several in various areas of the box, make the air currents work to your advantage
90mm fans would work perfectly, maybe 6 or 7 of them and just get a $20 200 watt power supply and u can rewire the molex plugs so that the wires are a lot longer, then get the adapters for computer fan plug
and for exhauset have a large duct, you could run it from a cool tube then have the carbon on the ooutside, using the air pressure inside the box to force air through the cool tube and out through the carbon scrubber
otherwise if u get a more powerful fan, it could be used along the same lines as what i just said, or you could use it as an active exhaust with the carbon filter
you probably want negative pressure in your growbox though, so id go with a more powerful fan set as an active exhaust, and then drill several holes for passive air intake, that insures that even if it not exactly airtight the smell is forced through the carbon filter
more powerful fans arent nessecary, but they help in a negatively pressurized system like this, the carbon filter could slow down the air flow a bit
and the cool tube has two functions really, it keeps the hps cool, and it heats the air before going to the carbon filter, possibly increasing the effectiveness? just remember to have a slightly larger carbon scrubber than you need
just make sure you have adequate intake and that your intake holes dont whistle lol

i already have two 5" computer fans that are wire up to an adapter...but i was thinking of just getting a blower and putting a carbon filter on it. i'd much rather have passive air intake. then i could use my two 5" fans for air circulation inside the box.
can these blowers be set up so that the speed of them can be adjusted?
how big of a blower would i need for my box that is 24 cubic feet? i think i read that they should be twice the size or something like that.
would one blower cool down the box with the 250 watt HPS in it? what about when i add the 150 watt HPS for flowering?

id say upwards of 30ish cfm would be ok, just go for an in line ducting fan, and if possible you can even vent up into the attic
your cabinet is pretty small so u dont need the most powerful fan u can get for it

use something like this for the light, it goes into the actual exhaust ducting and the air flow cools the light so a lot less of the heat goes into the grow box
also, why not just run a 400watt on a digital ballast? much simpler and ganja cant really get too much light, plus many people say that 400 is more efficient than 200, while the digital balast extends the life of the bulb, cuts out noise, and saves electricity
