Does A Carbon Filter Remove 100% Smell

Does it remove 100% of the smell, or just some. Will I be able to have a grow with a can filter, and still be able to have people come and go without noticing any suspicious odor? I did a google search, and a forum search, but did not come to any concrete answers.

My mom stopped by a few weeks ago and was in the room with Blue Cheese 4 weeks into flower for about 5 minutes and didn't notice. I am sure from childhood that she knows the smell and would have bitched at me too. My chick's parents were here for a few hours when they were a bit further along, but I don't know how familiar they are with the smell. Close to harvest I can catch a faint whiff myself if I'm in the same room.

Carbon works pretty good, but if you're like me and enjoy watching the plants frequently then the smell just works its way around the house. Gotta keep them closed up for a few hours at least to let the lingering scent dissipate.

I should add that I use home-made filters that I feel are pretty well put together, but I can only assume that a can filter from the hydro store would maybe work a bit better.

...it depends if you get the appropriate size carbon filter, and appropriate size fan. They both come in sizes of CFM's (cubic feet per minute)...this is an estimated measurement of the air it moves in a minutes time. You need to move your air 5 times per minute through each to be safe. So, if you have a hunderd sq feet to exaust, you'll want 500 cfm for both filter and fan.

Thanks for the reply, im planning on growing low ryders, hopefully it will work out.

LxWxH = qubic square feet , btw. Length x Width x height

cubic feet, not cubic square feet

Lowryder1 &2 are VERY Stinky SKUNKY lil bastards!
The least smelly auto ive grown was Automaria-

Hey i was thinking of making something like this to hide the smell from my mom(who is familiar with the smell and would probably pick it up if it just reeked of skunk) , my dad knows bout it and just said to keep it from her would probably be best. We have an enclosed room in the basement where the grow would be probably under the stairs, question is, if she walked into that room would she pick it up or if i made one or two carbon filters for it would that be able to cover it enough. Another question if anyone knows, in this little enclosed room we smoke a lot of cigarettes, would the smoke being in the air all the time affect the growth of the plant? or would it be beneficial in covering the smell ( we are allowed to smoke cigarettes in the house, not buds). Thanks!!

I've heard that nicotine is very bad for your plants, so you defiantly don't want to smoke in the room with your plants.

the OZN-1 ozone generator works great ,smells a little funny while running. The box say it smells like after a rain storm i dont think so. my 24x12 phat filter was not doing the trick for the price OZN-1 did OZN-1 $140ish phat filer $230ish

Any smoke clogs the stomata of your plants and will kill them in time.

a proper filter will work, ozone gen for backup

A carbon filter will only get rid of 100% smell when you have adequate ventillation, negative air pressure at all times and the correct size filter for your ventillation system. Also some cheaper carbon filters are not good enough to work as they should so buy a good one to be safe.

My plants have not been flowered yet, but I have a 100% smell proof grow so far. That is atleast until the tents are opened and then it stinks. The smell lingers for a while after the tents are closed up again, so you may want some additional backup like ona gel to get rid of the residual smells quicker.

THIS is exactly what I do and my house smells clean

You should move your air 1x per 5 min, not 5 times per 1 min! 500 cfm would be suited for a room of 2000+ cubic feet, assuming it is installed properly. I have test many fans, and the majority of the time the cfm is inaccuate(and this may be the your issue). A 100 cubic foot room (@ size of a large fridge) can be vented with a small squirrel fan or even computer fans. if the carbon filter is installed corrected in your exhaust it will remove the majority of smell, and you must also anticipate about 5% resistance to your exhaust system. @trichlone fiend I can assure you haven't installed a 500cfm in a 100^3ft room, as it would be too powerful and literally suck your plants out of the pots! In a larger room, if your lighting exhaust connects to your room exhaust, a 500cfm would be feasible for a 1000 cubic foot room. Ventilation is very important, always make sure you have at least 1 room exhaust fan, if professional lighting, a fan for that, and fans for circulating air. If you do not use CO2 make sure you have an opening or another fan to bring fresh air inside. Exhaust is for temp control and CO2. Please review information, as this will confuse beginner gardeners and hurt/destroy their garden.

I need to know the very best kind of filter to buy for 100% removal of grow smell in a single plant closet grow. I'm using grow light, hydro pot, maybe a TENT, if it will reduce odour. I've heard that lemonseedgrass oil works well for lingering odor. Not lemonseed oil, but lemonseedgrass oil, a little in a bucket of water, under a fan rids smell very well, but I still need to know the best filter and size to get, for a single plant closet grow. I am trying to stay unnoticed, even by other members of the household. So, I really need a magic trick here guys. Someone please gimme some real good tips, from their own experience please. No, I heard someone say crap, I need 100% facts from personal experience. Thanks fellow naturists.

Hello,

I'm using a 91lb carbon filter with a 8" inline (750cfm) fan in a 11x11 room and it works great however it is not 100%. It is used as a scrubber not exhaust. Some smell still leaks out not much though, barely noticeable. Not a sealed room either.

Use a decent filter plus ona gel in the room.
