The end of carbon filters...?

dbkick said:

ever recorded the IAQ after a explosive device or two go off inside? air tight isn't required but negative pressure is and with most every fan/filter combo if you're exhausting you're gonna have negative pressure.

I don't know much about IAQ, but yeah, carbon filter is surely good enough since everyone is using it.

to the OP: I guess there are no problems regarding MJ smell for those who know what they are doing. Maybe instead you can help those who don't and make a thread explaining how to make sure you're keeping odors down.

My problem is that I do not, and have never, grown.

Again, with my personal in-experience

have never grown and have very limited experience

hat is correct that I have not grown and that I am inexperienced

I am the first to say I do not have experience

AGAIN, I am not experienced with the entire process,

But with my LIMITED experience I

because of my ADMITTED IN-experience.

I am IN-EXPERIENCED

I think I just got trolled

Pure Growing said:

Seriously? So out of all of that only newbie9 is the only one to even attempt to offer any type of advice whatsoever. So thank you i really appreciate that. And I agree growindank about the writing, but apparently the formatting does not come through. I also apologize for writing so much, I'm used to writing longer educational speeches, which I now see is not needed here. All I asked for was information because of my ADMITTED IN-experience. Never once did I try to sell anything. I have 192 commercial, residential and industrial IAQ products in my catalog, each doing something slightly different. So I thought, hey maybe some nice stoner (apparently not the friendliest) "friends" could help me narrow it down a little because, like I said, again, I am IN-EXPERIENCED. I never once claimed to know anything 100% (except for IAQ). I believe I even said, I wasn't sure it was even a problem. And yes you are correct, if I could get something that worked better then yes I would make it available for people to purchase, just as I will have to purchase, and I will add extra money to the product, for me, for said product. If you can find someone giving away equipment or materials and not making any money on it, please let me know so I can start purchasing from them. Look, all anyone had to say was everything we use for air quality works well enough, there are no problems. Which I know is not true, from reading posts. Sorry, I'm being long winded again. Appearantly I have nothing to offer here, so thank you for your time.

If you ask me, tallen gave you advice so good it could end the thread. A properly-installed carbon filter will stealth that house. I have been very impressed with mine. I also own and use an ozone generator, but sporadically "prn" as health pros say. I have found the combo to be not only effective, but comprehensively so, and the ozonator is also excellent for dealing with bad odors at both ends of the food prep/consumption chain. The ozonator must be used in a thoughtful and skilled manner, but I am both. cn

i have an 11 x 11 room. this march, will be three years on the present filter. i check, and no smell. so how long can i expect it to last? its a big can, at 31 lb.

Ok first off let me warn some of the more sensitive ones, the formatting will probably be messed up and for some of you tired readers this may be a long post, continue only by choice! Apparently a lot of things need to be cleared up. I couldn't figure out why so many are.... confused, about what I'm actually saying in this thread, so apparently it must be my fault. I thought I was clear, obviously not. For that, I apologize. Let me try to explain this in a clearer outline:
1. I am not here with the intention to teach, coach, guide or even suggest anything for anyone to use or try.
2. I am not offering, or claiming, to have any type of "magic" cure or special powers or even an answer to any specific question. The title of this thread contained a question mark. All I am ASKING for is information. Nothing more, nothing less.
3. At no point have I, nor will I, try to sell you anything.
4. I am one single person working by myself. I am not a spammer nor do I work for a larger corporation, other then myself.
5. I exaggerate my inexperience because the information I was hoping to obtain would be known best by experienced growers.
6. Not one of the products I work with have been tested in a marijuana growing environment. Which means, most people growing marijuana, most likely, do not know they even exist, therefore, are probably not using them.
7. I am aware of how these machines operate and what benefits/consequences they would have on/around different materials and environments. You are aware of what you would like a machine to do and what not to effect.
8. The (hopeful) information I would obtain would help me narrow down 1-3 products that could fit most. Then I, myself, would then purchase and test said products in an actual marijuana growing environment. For only myself, even in no one else cares.
9. "Assuming" (which might be a pretty big assumption) anybody would even care, I could possibly start a journal or something to show procedure and results of this testing.
10. Let's "pretend" that something Could be, god forbid I say.....more efficient, then currently used methods, then why wouldn't another group of people, who could also benefit, not want to even know of its existence.

That is all I will, and have ever, ASKED for. I have not (apparently in confusing terms), nor do I, make any type of claim to even know 100% that something else even exists that could possibly work better. To some, I apparently came off differently, for that I am sorry. Your participation is completely voluntary and your input thoroughly appreciated. If nobody is interested in offering me any useful information, that is fine as well. Again, this is just a friendly ASK of some pertinent information. Hopefully, now outlined and with less verbiage, it is clear what this thread was intended to be, and hopefully can continue to be, about.

So are you asking for specifications for grow rooms as it relates to recirculating air, or are you asking for specific problems beyond the odor issue? Generally (and I'm a noob, so I don't really know) it seems like heat/humidity/co2/smells/noise are the big ones I've seen talked about with respect to air.

Why is everyone so satisfied with having to own two forms of odor/air control? Having to run Ozone and Carbon Filters is a pain in my ass.

Carbon Filters may work well, but in order to work properly you absolutely have to match up the CFM with your space and fan, that is essential. But I believe we will all agree, that outside of micro cab/closet grows, the filter is always way damn bigger than we'd prefer. Hanging a filter in a cheap tent can make them flimsy, and at the very least cut out a lot of real estate for my lamps, and forces me to mount more equipment outside my tent. When using one in a grow room, I always think that I would much rather use the space for a reservoir or if mounting to the ceiling, more head room for my equipment or to use higher tables to give my back a rest.

Being expensive and heavy is my biggest beef.

Using your Ozone Generator properly is essential to safety, and having read the instructions and researching ahead of time, I have never had an issue. I don't think anyone should be wildly spending money on something they have no idea about, however, Darwinism. Ozone is another thing you have to go over kill with, and to do it properly can sometimes require elaborate mechanisms and ventilation if you're set up isn't ideal.

I just want something easy, and something that isn't going to affect my buds. More importantly I want something to kill Spores, and the harder it makes life on bugs the better, I don't use beneficial predators.



Something has to be lighter, more compact (if only by a little), cannot produce heat, the more quiet the better, and something I can ventilate back into my own air space if I needed too. Preferably something that didn't take up a bitch-load of electricity on the account that everything I use takes a bitch-load of power as it is.

And, hopefully, something that wouldn't be interfered with by a sulfur burner, because while I wouldn't leave one running with the vent on, but I will need to get that vapor out of there somehow. And cannabis is very oily, so anything that can handle that.

Basically, I need something perfect, but that doesn't exist so the next closest thing will do just fine.

Pure growing...My 12 x 15 with many plants goes through about $1k a year in carbon filters. I overdo it. Many would use 1/2 as much in the same space... They work very well. If you can smell from a friends driveway then your friend is not on top of his setup.They used to be super heavy, but now there are lighter carbon filters...I guess you would have to match effectiveness and beat the price to really make it take off.... or match the price combined with some intense marketing. A smaller size would be convenient as well.

I suppose if you were able to both remove the smell and the moisture in the air upon exhausting then I would be interested. This is because I exhaust to an attic where the air then passively flows outdoors.

I have not got enough time to read through every post here.

But from what I gather OP your daughter lives somewhere that's already growing. Correct?

You can smell the grow around the house and yard correct?

Then this grow has not been properly setup. It's as simple as that.

You're a HVAC guy so this should be easy enough for you to understand.


The CFM of your EXHAUST fan should NEVER be bigger than the CFM of your CARBON FILTER. This allows the filter to run at its best performance. Air moving too fast over the carbon bed in the filter and it doesn't clean the air effectively.

Secondly you should have more air being exhausted than what's being drawn in through intakes thus creating NEGATIVE pressure within a room. This negative pressure means that ALL air leaving the room goes through the carbon filter.

By choosing good quality filters that use high grade carbon you should never have a smell to deal with.

As for mould etc weekly bleach cleaning of your environment used for growing is generally enough to stop anything from forming. This along with keeping RH relative humidity within optimum levels is fine.

OP,
If you really want to help us out as you claim, them put yourself in our position.

You claim to have been around grow houses and grow closets, so you should understand how we handle the odor, mold, and bug problems...not including other problems like heat, temp, humidity, etc.

That all said do your own A/B comparisions between what is offered now and what you can suggest. You can spend as much time as you like writing white papers and technical journals on what you find in your research. Heck, you can write about closet grows, 6x6's. 8x8's, 10x10's, 12x15's or whatever size room and condition you can IMAGINE.

I've run on long enough. If you want to help, help, but do not try to sell us anything....and that does appear to be your intention..
No flame, just fact.

Thank you so very much Jozikins!! That is EXACTLY what I have been asking for. So it's not JUST me. Thank you for understanding what I'm saying/asking!
Jondamon - I'm sure it probably is not set up correctly, your comment about negative pressure is very true, however, depending on the location of the room, that may be a dangerous practice as well. People who grow in a basement or their mechanical room (where the furnace, water heater, etc. is) that create a negative will cause the furnace and water heater vent exhaust gases (carbon monoxide) to be pulled into the house, while running, instead of exhausting out the chimney. Assuming they do not have a sealed combustion furnace and w/h.
brother numsi - yes I have minor experience around them. I do understand how most people handle those problems. There are MANY different grow environments; rooms, houses, greenhouse, basements, closets, drawers, cabs, etc. I'm looking for what issues these things have specifically in common (something I thought would be as easy asking). I'm not interested in what people are currently using to manage these problems, I'm only interested in what the actual problems are. I can't write about different size rooms and such, since I know nothing about them and do not have access to very many places to write about. Was hoping to learn from others experience. I'm not looking to do an AB comparison with ANY products. Just curios about existing problems. That is it.

OP,
From your original post:

• "Then, hopefully, I'll have access to a much more efficient solution to one of your/mine/our/horticulturists/marijuana consumers (apparently everywhere?) problems. I'm about 90% sure I have at least one product that will work better, be more efficient, probably cheaper, and much smaller then the carbon filter setup and the others. From what I've seen (after weeks of searching for a better solution for the collective, us) I believe I can produce something that could benefit everyone."
  
  Now re-read that and then tell me again how many of us may have misinterpreted the idea that you didn't have access to or might produce something to "help" us i.e. sell us.
  
  Why not list, say 10 products, and describe what those products might do since the only people who ask about ventilation and odor are the most inexperienced.
  
  Another way to put it, most of us haven't run into a problem that either wasn't solved by posters on RIU or doing some research on our own.​
  
  

The short story is that you are trying to tell us our methods are wrong and do not work when we personally find no issue with them. You can devise any contraption you like but most of us have found that a carbon filter used correctly works just fine

You're not very good at reading are you. I think it's time you stop wasting your own time, and start being productive in this discussion. Otherwise, just go ahead and leave because you really aren't contributing anything whatsoever.

Ok to "anyone" who actually read and got the point of what I wrote or could possibly be interested in the progress/evolution of more advanced technology, I'm very sorry but I am done here. My account will temporarily be left open if you have any useful information, are actually willing to help me, is possibly open to advancement, or even have any RELEVANT questions, please feel free to PM me. To everyone else, apparently what I'm asking is being VERY misconstrued or not an acceptable practice in this forum. At no time, have I asked anyone to completely ignore any point I was making and focus solely on trying to pick apart my posts just to comment on how you think one, or more, of the, completely irrelevant to the point, statements I made are, in your opinion, not true. This does nothing to help/benefit/progress/educate anyone involved, with the exception, obviously, to your own ego. I am not here for that purpose. This is not what I expected at all and apparently its my bad for having too high of expectations from most that replied. I am a business owner/entrepreneur who has started and operated a successful HVAC company. One thing that has proved to add a lot of benefit to consumers is the fact that I, and most, industries offer free information. When ANYONE calls me about a question, consultation, sales call, or even minor troubleshooting issues, I offer them any knowledge that I have pertaining to their issue, free of charge. As most industries find this to be common practice (excluding a few, lawyers and such) I assumed here would be no different. I am done having to defend myself and my intentions for merely trying to obtain free knowledge from what I thought was an acceptable outlet. I would still like to thank EVERYONE for your time (for at least responding, no matter how misguided or rude). I have def obtained some knowledge from this experience, unfortunately not the type I was looking for, but useful nonetheless. I still hope one day you will be open and willing (apparently un-necessary and un-wanted by most at this time) to accept advancement or technological progress in this industry. And one last time just to make it perfectly clear, I was NEVER going to ask ANYONE to purchase ANYTHING! Simply educate and provide definitive information about any results, only then, should anyone be interested, would it be available for purchase only upon YOUR request, not my asking. I run my business the same way, as I am NOT, and never claimed to be, a salesman. I only educate on possible benefits/solutions, then my clients can tell me, under their own willpower, what services they would like me to provide. Again thank you for taking the time to read ANOTHER long post and I wish you all the best in your future endeavors.

I agree, I am definitely wasting my time. Thank you

OP,
Did not intend to push you away, but your entrance to this forum was very awkward and somewhat confusing.
As I suggested, if you want a discussion, list 10 products, maybe with pix, and an explanation of what they do.
That may be a shotgun approach, but maybe more acceptable, too.

The formatting is all screwed up on this site....................Yep, I ain't reading all that shit. Fool me once, shame on you. Fool me twice, shame on me.I am confused at the people in this thread that think carbon filters are difficult, dangerous, ineffective, expensive...I use two carbon filters for a 3 x 3 tent in my furnace room. One is inside the tent at the top, using space that plants and lights can not use. My tent is no where near air tight. The other, which is not necessary, puts filtered air into the tent. I only use it to clean the air going into the tent. If I were creating negative pressure in my furnace room, it would make the hot, carbon monoxide air from my water heater etc. want to leave through the proper vents. I do not see how creating negative pressure would make warm, carbon monoxide back up into a room. As for dangerous: My setup is not dangerous at all. If anything it cleans the air that is recirculated into the house. It seems this thread has done nothing but fan the flames of ignorance.......................................Does anyone want to talk about feminized seeds now?
