Odour control - tent within a tent?

Probably a retarded idea, but here goes anyway:

For those of us growing in an urban dwelling where effective odour control is essential, would a grow tent within another tent be a viable option? I.E. A regular setup, complete with carbon filter etc. (say a 4x8 tent) in turn housed within a larger sized tent (say, 5x9 with increased height) that contained an additional carbon filter, either within the 2nd tent itself, or indeed exhausting from it. Although I suspect exhausting from an outer tent might cause all sorts of air-flow problems for the inner grow room, so perhaps just running a filter within that outer tent would be the way to go..? Would this not, in theory, create a lot less odour escape when entering/ leaving the grow tent? Would it not also create a generally more contained environment for odour treatment as a whole?

I can see why this might be a bad idea for those running hot lighting systems and needing to vent away lots of heat, but for growers in cooler climates, who're using LED lighting, what would the downside be, except the obvious initial extra cost? Also, the outer tent could presumably be one of inferior quality to the one chosen for housing the treasured babies, as it's function would be far simpler (perhaps also a decent place to keep a germination chamber, or even some plants at veg' stage, with different lighting needs come to think of it).

I'm not arrogant enough to believe I'm the 1st person to come up with the idea at the embryo stages of planning my first ever setup, while others have been at it literally for decades and I'm sure there's a good reason why this is a really stupid idea! So would someone with more brain cells than me please be kind enough to tell me why this is not a good idea? THANKS!

this is a good idea but I cant test it because another bigger tent is most expensive and I have no money
Even with a few quid to spend on my setup, realistically, I can't see myself laying out the extra for a 2nd tent instead of buying say better lighting. But in theory, it seemed logical to me and I wanted to float it as an idea to see if that "2nd layer" type approach was something that had been done/tried before and whether there's some glaringly obvious reason it would not in fact work as well as imagined.

There could be growers out there for whom this investment might be worthwhile (in apartment blocks/condo's), if it made a huge difference to odour control. And if some new odour control technique were established, regardless of cost, there may be cases where some people who would not have felt comfortable growing, were able to consider it.

I like the idea, myself living in an apartment, when the tent is opened there is some odour release to the extent that I avoid opening my front door to visitors for some time after I close it up.

SO in your case, it would be something like a 5ft x5ft tent, but it would also have to be adjustable to 7ft in height.
There may be cheaper options, but something like: http://www.hydroponics.net/i/140746 OR http://www.hydroponics.net/i/140747

Then there's the additional air filter too e.g....http://www.hydroponics.net/i/136249

Again, I know nothing at all about filtration yet, so this might not be the most effective or best value option.

In any case, my idea with these materials would cost in the region of $570 with the larger tent option, which would better represent what I had in mind - a 2nd air controlled area which the grower could seal (and even change clothes in) upon entering/exiting the grow room. If odour control is a major concern, that doesn't seem overly excessive to me. But of course, everything is relative to personal circumstance, especially where cash is concerned!

I'd still like to hear any reasons it might not be effective or any problems it could cause for the interior grow room, if anyone out there can think of anything please.

Just my two sense as I had the same problem. My first official grow I had a cheese strain and it STANK. Worse than that it makes you paranoid to hell. I found a simple not too expensive way... The company I work for has an odour control sector for large food companies. They use special chemicals that neutralise smells not mask them. Got me to thinking I could create a quite simple misting spray. Basically I rigged a system to spray the odour lch formula I got off the Internet into my carbon filter on a timer. Literally inside and around my house smells amazing. I could leave the tent open and the only time you could smell it was when you stuck your nose of the bud!!

Hmmmm what was the formula called?

Iirc it was called neusol dv. Or neurosol dv. I used that and then a battery operated mister that has a timer inside my carbon filter and it worked amazingly well. A friend also suggested using the same idea but putting ona or something similar to that inside the filter. Basically turned my filter system into a massive air freshener!

I use ona blocks in my tent and don't have any odour issues.
These are brilliant things and every grower should use them.
Just google ona blocks not ona gel and it will give you more info.
I use the fresh linen scent and it does not mask the aroma it neutralises it and is perfectly safe to use near your plants.

That's fantastic! Would you mind posting a link to where I/we might find what's needed to set this up please? Thanks!!!

Sure ill see if I can dig out the website. I know that ona do a virtually identical setup but with their own chemical products which I would imagine are all roughly the same base compounds. The company I work for have huge ibc's of the concentrated stuff they use for food factories to control their odours so I was able to grab some and when j mean some j literally only needed like 10ml that lasted me my whole grow because it was so concentrated.
Found a very similar ono one;
http://www.hg-hydroponics.co.uk/ona-mist--dispenser-odour-remover-385-p.asp

I basically brought the dispenser with fillable container and used my works solution. Put set that on 15 minute intervals and put it inside my carbon filter, then the air coming out smells awsome. Might be worth trying the ona version I hear a lot of people swear by it!

I use the ona bucket and it works awesome, but apparently i was told u shouldnt use ona inside ur actual tent, it sucks the smell out of ur buds, but idk the authenticity of that statement.

Well I guess even though mine is kind of inside my tent as my fan sucking air out is constantly on I would assume the odour neutraliser isn't really going to be inside my tent as it's being constantly sucked out, along with the air that smells so lovely of weed lol

Yup, I'm familiar with Ona proucts. Thought perhaps it was a different concept. Always good to know as many products as possible though!

I was thinking of something as an additional layer of odour protection for those already using a carbon scrubber and Ona-like products outside the tent (I've also read that about Ona).

An alternative to a tent within a tent, might be a smaller tent (cheaper than a larger one), with filter installed, connected with seals at a doorway and used as an entrance/exit point.
