I have a 32"x32"x63" tent with a 4" carbon filter/ fan combo. I have the filter in the tent, ducted to the fan which hangs outside the tent, and then ducted to the outside. The only time we smell weed is if I have the tent open.
I doubt that it’s your carbon filter if it do not smell in your grow room but not impossible if you’re connect to your main ducting system and/or if your carbon filter is “due” and /or if your CFM power is “over killing” your growing space and filter capacity.
Where do you stach your stock and where do you smoke it and fabric retain a lot of weed smell, so, where is your laundry bucket can affect too the smell in a house, imo, but @Countryboyjvd1971 is the reference here for HVAC.
Funny you should mention this, cause I was just noticing that my bedroom smells of weed and that’s where my tent is. I have a 4" carbon filter and a good fan on high and it still smells. Honestly, i don’t know if there’s anything that will take care of the smell completely, sorry. Luckily for me, I’m only a week away from harvest.
I’ve had pretty good luck with can and phresh, but that’s all I’ve used. @Niala is correct that you want to size to cfm of your fan. If anything, I usually get a filter that’s on larger side than smaller, seems to put a little less drag on the fan and more surface area usually lasts a little longer.
I currently only have a whole room filter, nothing inside the tents. My grow room is next to my bedroom. We have a drop ceiling. My bedroom also has a whole room filter, which I think pulls in smells from the grow room.
I am looking for recommendations on an in-tent filtration system, which is good quality, energy efficient, and fairly quiet.
Ac infinity and hyper fan are about as efficient as I’ve seen. Both should be available via amazon, the ac infinity has some really cool features. Definitely worth checking out. The one thing I’ll say though is that 4” doesn’t deal great with static pressure of carbon filter. @Covertgrower has the 6”, seemed to be working good. He can probably tell you more on that
Ok then, if you want Amazon prime, you have to live somewhere that they offer the services, I do not know if they offer this services for Alaska, maybe @Covertgrower or @GreenThunder that I know they living in your part of the world can help you further with this. @dbrn32 give you great possible names of relialble filters, does amazon offer "prime"in your region for those, I don’t know, you’ll have to make your own research for that, @blackthumbbetty
Ok Betty, you have 2 tent, one is 40 cubic feet and the other is 75 cubic feet.
CFM needs are: you have to run at least 1 times your cubic feet per 3 minutes, but you have to consider temperature, humidity, carbon filter and CO2 if you inject and do it at saturation.
I made a topic espacelly for that and invite you to consult it…
So, for 40 cubic feet you’ll need
40÷3= around 13.5 CFM
Add 5% for each lights you have, so, I presume that you have 2 lights fixtures so 10% more = 14.85 CFM, add 20% for your carbon filter = 17.82 CFM if you have temperature issues, add 25%, add 40 if you have also humidity issues, so, 22.28 CFM for heat issues and 24.95 CFM, so, 25 CFM should be enough for the smaller one (2×4×5)
You just need to apply this on the other one, but it should give you around 40-45 CFM,
These are absolute minimum.
I will let you choose your options or I let someone else guide you further.
Ôôôô, I suspect it but now have the confirmation dear Betty
Sorry for your lost, but shit happens, lol Sometimes, it’s just too late for intervention… A good start and keeping your environnemental numbers right and pH level right too , make all the difference, way before nutrients, but they have their importance too, all depends on their avaibility …
@Niala@blackthumbbetty am-zon prime is offered to AK. It’s never “2nd day shipping” more like 4 day, but it gets here.
I have “can lite” carbon filter. It’s really big and it filters really well. @dbrn32
Pretty sure @Niala has you covered, good information there Al!
All I meant was that if I was looking at say 6” filters for my 315 cfm fan and narrowed down to a 300 cfm filter and a 350 cfm filter, I would choose the 350 assuming quality was the same or better. Both will work. What you really don’t want to do is buy a 200 cfm filter for the same fan. It will pull the performance down quite a bit.
