Mr Piggy, I have to whole heartedly disagree about ONA products. :scope: The ONA products absolutely DO work and I will go blue in the face defending them because I have used them, tried every single one of their "residential" product line minus the 5 gallon buckets and commercial products and they do indeed work if you USE AS INTENDED. I also have documented in my grow journals here on AFN my purchases and use of ONA products. Putting a quart jar in a huge tent or a huge room and expecting zero smells is having the wrong expectations for your product. I've even written product reviews on several sites for them; call me a fan boy if you like but the products do work if you have the correct expectations for what you are buying. The ONA product must be suited to the environment and cubic space you are putting it in. Air circulation and air flow factor in how well these products work. I use the ONA blocks in my bathroom, quart jars next to my litter boxes. ONA is only effective for larger spaces in larger concentrations, commercial concentrations, and with additional fan circulation. That's not a product defect; that's a product specification.
HOWEVER, in case my previous posts were not clear or were misleading, his number one solution is going to be a carbon scrubber. My point was that a carbon scrubber will do jack squat if he doesn't tighten up the air holes in his closet so he CAN create a negative air pressure space. My carbon scrubber did wonders for my tent, but it did NOT ELIMINATE the smells completely. Very few things operate at 100% efficiency in this world and a carbon scrubber is no exception (I run 400 CFM centrifuges on my 6" scrubbers, I would have gone with a 700 CFM fan now that I've seen it in action); and it does the job and it does the job well; but it will not eliminate all of his odors. ONA should be treated as an ADDITIONAL smell prevention and control measure, not a sole smell prevention measure. With my 6" scrubber and an ONA mister, I smell NOTHING with my nose right up to the zipper with a tent full of plants. If I just run the scrubber, my basement and back pantry smell like marijuana growing. If I turn off the carbon scrubber, in 15 minutes my house smells like a grow op. Everyone's situation will vary depending on many variables, but this is my personal experience, so feel free to take from it what you will.
If it were ME, and I say this solely as a suggestive opinion; but my first order of business would be to get my closet as air tight as I can so that I have a much more controlled environment for my ventilation.
Second, I would make a diagram figuring out how I'm getting my fresh air into my closet and what my plan is for exhausting it.
Third, I would figure out what size carbon scrubber I need and what CFM rated fan I needed to utilize it for the cubic space of your closet. Carbon scrubbers are far more effective when you have a fan sucking air through them than they are if you have an exhaust fan pushing air into it (so instead of having your fan pushing air out of the tent down a piece of duct INTO the scrubber, it's better to have the scrubber in the tent with a fan on top of it, sucking air up and through the scrubber and exhausting out. If you need proof of this, try reversing your fans on your scrubbers sometime and listen to the pitch the fan blades make. If you notice a difference in sound, case in point.
Fourth, I would see how well the scrubber is working before going overkill. If you are financially strapped, this is your best option. If budget isn't too important, than you can play around with things. For me, I don't have a limiting budget, so I go for overkill because that's what helps me sleep at night.
What are some of the variables in your grow? Are you in a house or apartment? Do you share walls with one or several neighbors? Basement or top floor apartment? You make mention of sound being an issue; maybe you should try to find a 400 CFM fan turned on so you can decide how loud is too loud. I can hear my 400 CFM fan (with freshly lubricated bearings) two rooms away and up the stairs. You may not even need a fan or scrubber that big. How many plants are you growing? What strains are you growing? I've had plants with no smell. I've had plants that smell spicy, like pepper. I had 27 seedlings started in a small box one time and despite being less than two weeks old, they REEKED like marijuana haha! Seriously, like a hardcore pungent dankness. Off seedlings with barely any leaves!
Hermdog, the most important thing is that you learn to try some things for yourself. One thing I've noticed (and AFN is no exception), you will get a lot of advice. Lots of GREAT advice. Some mediocre advice. Sometimes BAD (hopefully not) advice. I've tried things suggested by members with thousands of posts and epicly high reputation, and I found out I HATED those suggestions. Not that they were bad suggestions; and they most likely work and work very well for the people suggesting it; but sometimes you have to take this stuff with a grain of salt and learn what works for you. Have you ever heard the expression "there's more than one way to skin a cat?" Well there's more than one way to grow pot. Don't get caught up in one man's way when you are your own man and are capable of making mistakes and learning from 'em! My first grow was pitiful. My second grow was 10 times better. My 3rd grow was an entire cured pound of ridiculous awesome. My best advice I can give you is to learn to discern on here what is more fact than what is personal bias. Sometimes fact is mixed with bias! And that's not always a bad thing; I don't think anyone is really on here trying to give malicious info out to anyone. You'll find out what works for you. Just remember, like the others have stated, it is only to your benefit and safety that you take these precautions BEFORE you have a problem. ONA and carbon scrubbers won't do anything for you if your neighbors already smell the growing pot and called the cops (or worse.) Best of luck to ya bud!
Good luck brotha!
