I wanted to get a conversation rolling about everybody's set up for environment exhaust and outdoor control. Some lucky members have the luxury of living in a legal environment. They don't have to concern themselves as much with odor as many other farmers out there. Although I'm sure a majority of everybody out there does take necessary precautions.

So, let's hear the basic stats related to your space and equipment used for exhaust and keeping the stink to a minimum. Maybe any issues you may have had in the past and how you solved them.

Currently
200 cf grow tents
1k hps (air cooled thru exhaust)
Hydrofarm 165 4" fan (full power, 24/7)
4" x20" 350cfm Phat filter

This is exhausted out the basement window. I usually have odor after 6 months of filter use. I've tried the smaller 4" filters with no luck. Speed controllers? Different filter? Fan? I'm struggling and in need of some help.

Got 2 600 hps’ and a 315 cmh added when it gets cold enough in the flower room and a drying closet for the perpetual harvests filtering through a pair of 6” inline fans and a .6”x18” 400cfm phresh filter.

In summer the exhaust goes out the chimney but in winter right into the basement and out under the living room.

No one has smelled the garden or drying flowers if all closed up.

What's the cubic ft of your space? In relation to the size fans and filters? Speed controllers or wide open? Run 24/7?

The room is about 400 cubic feet but the grow footprint is usually less than half of that.

Speed controllers have to be above the marked 35% on the hyper fan controller or smell will escape. They change speed often as our variable weather.

I also have a pair of 6” intake fans bringing air in from the adjacent lung and veg room. They run at half speed max.

I've read somewhere the idea of a speed controller is to increase the efficiency of the filter. Slowing the airflow to allow the carbon to capture odor more effectively. Who's using what? I've also read those simple $19.95 dial controllers suck. Recommendations on speed controllers...
Or, fans that have factory controller...

I have hyper fans which have a built in speed controller. They only dial down to 35% power. And i have the green active air inline fans and their cheap controllers and they have all worked well running 24/7 for 4-6 years. I do filter intakes for dust so there is no buildup.

Vortex fans flipped backwards, always scrubbing no need for extra piping.

i use double end filter,after 2 or 3 grows just flip it around ,the filter only use the half by the fan,mine is about 18 in long and i didnt realize the back half wasnt even used until i took one apart to clean charcoal,also found that the charcoal was coco husk,i sweep it with a propane torch to burn all pollen off put right back in filter can ,with it raining today might just be my project for the day

Carbon filter. Booooom rocket science. You're welcome.

Been using carbon filter. Trying to figure out the right combination of fan died and filter size. Not rocket science, but a little tricky being completely stealth odorless. Been set up for two years and can never stay odorless for more than three months at a time. You just use a carbon filter? Fan speed? Size of grow/ fan filter combo?

got about half way threw sweeping it and decided 4 years long enough,freaking filter are seriously priced outrages and refill of charcoal about same price

I remember having this conversation with you before about refurbishing your carbon filters. I like the idea.

Is high humidity a problem? Carbon filters do poorly in high humidity. I think phresh says keep inder 65% rh.

i finally threw one away yesterday,ive cleaned so much i had at least 3 cups of powder in it after dumping it out this last time,so i unass 52 bucks and got another ,it hurt bad buying at that price,seems like they should offer me a cigeratte after that fucking hahahahh.

Never breaks 50% in the room. I'm thinking a better speed controller to start. Or fan with controller. Not sure about the combination i have if it's well suited for my space. Probably undersized.

I've tried using one of them vary speed for my out take fan and when I tried to use it, it made my out take fan buzz.. It didn't sound healthy so I decided to not use it as my out take was a new one and didn't want to burn it out. My out take is having a negative pressure on my tent as the intake isn't as fast but it's all working well on my grow.
