I had an atrocious stealth grow going but I decided that if I was going to do this I ought to do it properly.
Here is my first attempt at a growbox - I'm leaving it completely backless for the time being. It's on a single Philips 18w (1100 lumen) CFL bulb till I get my envirolight fitting - is this even better than nothing?

Used to be an old pots and pans drawer - now its far more useful
I'll get exact measurements later but you can judge it by the scale of the lamp. Its quite shallow as it stands but I reckon I should be able to get maybe 2 full plants in their if I put them into 12/12 as soon as they reach about a foot high (plenty of scrogging as well obviously.
This being a stealth grow my primary concerns are saftey and smell.
I'm going to put three fans in - haven't a clue how I'm going to cut them out as I don't have a router but that's life. Two either side of the lamp and one close to the stems to stir the air up and stop them being so stalky.
I was initialy planning to put just a sheet of reflective mylar over the front - using that double-backed velcro tape - and have it up against a wall but I'm concerned about the smell - what would my best course of action be?
Full Version: First Grow Box
You will need a Carbon Filter matey and extraction fan on it to kill the stink, as for the rest not sure really, the pictures have not come up which you link to the post, most important tool for growing is the filter, safety first.
Just seen the pics, would get some mylar in there all the way round, get a reflector and up the wattage asap as they are stretching for the light, will need a slight fan blowing on the stems in a few days time to thicken the stems also.
Have you not got a closet or something, not much room from that pic matey, im wondering if you tip that box over you could do a sog with about 10-15 plants in there instead with reflector over head, carbon filter, extraction and a fan blowing over the plants.

Shouldn't be a problem for a couple of weeks so I'm getting my shit together now to try and sort it.
Would a pair of normal PC fans with some small carbon filter be enough to kill the smell? I can't do the whole oustide-extraction thing so any smell-killing is going to have to be built-in to the box. Also, if I velcro a sheet of mylar to the front of it would that let the smell out?
You will need proper extraction, there aint anyway around it, unless you have no probs with your whole house reeking of weed. You will need to fit a proper front on there as mylar wont do the trick. Me thinks you need to do some research.
you need to get that light horozontal m8, thats just absurd strech. as those guys say, line or paint the walls white. u can get or make a filter
but thay aint gonna smell for a while yet, the main thing now is to stop them streching before u have nothing to smell.
if its a choice of spending money on maylar or a light, get a light.

Yeah, when the envirolight fitting gets here (Have a 125w red spectrum) I'll be doing a proper horizontal mount, this will have to do for the meantime - they were getting so little sunlight where I had put them I had about half give up the ghost (the sole 2" or so seedling I put outside died it's first night). Going to mylar sheet the inside of the box completely. This is only a test grow with some bagseed anyways - the lowryder 2's will be getting 24/7 when they germinate.
"You will need proper extraction, there aint anyway around it, unless you have no probs with your whole house reeking of weed. You will need to fit a proper front on there as mylar wont do the trick. Me thinks you need to do some research."
I've done a good bit of research, most of it done into micro and stealth grows. Practically ever grow uses 4 120mm PC fans with active carbon in front of them and no other extraction. Do you reckon it isn't enough?
Whats my best option for a front realisticallly?
Cheers for all the input
I'm afraid stelth isnt something I do but fan wise I'm guesing for a box like that you'll need 1 in and 2 out with pc fans. thay wont have much pull but its not a massive box. basicly, yeah 
it should be enough 
oh for the front use the double velcro like u said then some sort of door, like a pice of ply or something that you can fit flush to it. should do it.

Right - first things first.
Got myself a metre and a half square of mylar sheeting. I'm going to coat the inside of the cabinet, set aside a cut piece for the back (for when I get around to making it) and use the rest to make a reflector to go around the Envirolight; the smallest reflector they had in any of the local shops is far too big for my purposes.
Whats the best way of going about mylaring the cabinet - using separate cut pieces for each side or trying to use a single whole piece and go around the box (or does it matter?). Whats the best way of gluing it on - would I need to get any special glue?
I was planning to get some chicken wire or similar and just glue the mylar to the framework to make the reflector - any obvious problems with this?
Cheers for bearing with me so far people, tis tough - especially since most of you have the luxury of not having to micro/stealth grow (and I've seen enough
YOU CAN'T GROW IN A 2 FOOT BOX WITH PC FANS AND ENVIROLIGHTS ranting on the forum to know people are making the effort here).

personnely mate id turn your enviro around so its lying horzontal... then make a reflector to suit that...i find you get better light that way.. also you dont have to use mylar you can use matt white paint for reflectability only matt though no gloss or anything shiny... if your determind to use mylar use a good quality double sided sticky tape if its going straight on to wood shouldnt be a problem...but id seal the inside of the grow room aswell to help prevent aroma and light leakage..
also what the othet guys said about fans and ventalation is dead right when you put a front on that room there wont be much oxygen in there for the girls,, bigger lungs on plants ,bigger plants ,bigger yield..
its not looking to bad just needs a bit of time spending on it before plants get to big ...
just an observasion how many plants you reckon you can have in flower in there ...? there doesnt seem a lot of room..

as for the mylar you can try to wall paper it mate but its a bit tight on the role prob best to cut it to size first get double sided and just get the top right and push it down like a piece of wall paper nice and tight. i did a fridge grow earlier this year very similiar if you need any advice id be happy to help out...
Cheers for all the advice.
Thats not the enviro - thats just a 1100 lumen energy saving bulb. I'm waiting on my e40 fitting. When I get it I'll definitely mount my enviro horizontal.
As for how many plants - I was thinking 2, maybe 3 tops, SCROG'd of course. If I can get an ounce from the box I'd be delighted.
That can reflector thing sounds perfect - definitely going to give that a go. I've the mylar bought already for pocket money prices but I've a sort of propogator in a wine box idea that I'm playing around with and I might paint that white inside as opposed to mylaring it.
As for leaving the front off - I have to put a front on it so no light/odour escapes. It's a stealth grow so it's key that it stays an ubiquitous wooden crate pushed behind a load of junk.
In terms of ventilation I've been reading up and there seems to be some fairly unanimous agreement that a 120mm PC fan simply won't cut it for pulling air through a carbon filter. Is it complete overkill to get an RVK (not too mention its bloody expensive)? It really is important that there be no smell.

you can get an rvk at any diy shop if its to much extraction get a timed one or even easier put a timer on a normal one thats what ive done ,,,
comes on every 15 mins , but if you want no smell and hide the box remember your door must be a good fit and you must be able to accsessssss the plants..
aswell as a carbon filter even then you will get some smell i would use neutrodol,s around the entire area to be confident and maybe an atomizer thing........
Yeah, just saw the RVK 100mm and they are *way* too big for my size of a box - look at my pictures above!
Basically, my choice now seems to be to stack 2 pairs of 120mm fans (i.e. two fans stuck back to back together with the centre-piece cut out) with some active carbon and hope for the best. The other option is to buy an o3 generator - I was in the friendly local headshop today and saw the 'pirahna' - seems the business but they were asking like £160 (200 euro) which is a tad expensive for something I couldn't be sure would even work 100%.

o3 as in ozone generator? i thiknk they are more for making the air better for ur plants, i might be mistaken but from what i understand they wont do the job 100% on getting rid of the smell and i read somewhere that ozone smells horrible i might be wrong of course...

i might be wrong of course...I think you're referring to ionizers - Ozone generators make the place smell like a hospital ward, while killing rather than masking the bacteria that cause smells.

[/quotejust get an extraction fan for a bathroom from focus, thats to much for that box you got.... so youl have to put it on a timer you wont need intake fans aswell on a box that size just use the extraction fan as a passive intake and make a couple of holes in the back of your box or the door close to the bottom..put some mesh over he intake holes to prevent insects and stuff... when i said ionizer you can get ionizer bulbs or a de-ioniser from ebay 4 40squid and they do the trick they clean the air as apposed to mask it, my mate has one it uses water and its really good..

Take a look at blabb's micro grow. He yields a good few Oz from 1 plant.
You can use pc fans and cooker hood filter but its not the best option but it seems to work very well for him.
Follow his grow diary and you wont go far wrong.
