cfm

Fellow growers. What's happening! I'm almost don't setting my indoor back up, been waiting on some new pieces. I just bought an anemometer to measure cfm and hoping someone in here can point me in the right direction for use. I have my exhaust fans on speed controllers and I want to get them...

Hello, My grow room is 25ft (L) x 10ft (W) x 9ft (H) = 2250 cubic feet. My room will have CO2 supplementation and only needs to exhaust heat as needed. Otherwise, no exhaust will be happening. I will have 6x1000watt HPS lights which will create almost 21000 BTUs of heat per hour. My goal with...

Hello. I'm setting up my first grow tent (a 3x3x6.5). I live where it's illegal to grow so I have to keep odor as close to non-existent as possible. I'm using a 400W Led panel and I bought a 5'' coconut-carbon filter rated 250 CFM (coconut carbon is supposed to be 15-25% better than regular...

Hi there, I need some help with correct fan sizing for a 30m x 8.5m x 3.35m(h)/ 100' x 28' x 11'(h). The added challenges are having to push or pull everything geothermal tubing, whilst not being so loud/power hungry. There is a lot to plan and not enough info readily available on the topic. I...

My walk in closet is 6x3x8 however I’m only using a portion of the closet to grow a few plants so my grow space area will be 3x3x6 (and that’s rounding everything up higher) I’m growing up against a window and I’m going to utilize the window to blow out the hot air.. I don’t mind not having a...

Hello, first of all I'm no artist but I'm proud to show you my sketch. Still trying to figure out which fan and filter I need for my grow. From what i found se need to do these math calculations: EUROPE (M³H) Tent size: 1.20x0.60x1.70=1.23m³ 1.3 X 60 (minutes) x 1.33 (25% filtre) =...

So I'm currently coming to an end of the things I need to start my growing experience which would be the fan size and carbon inline filter size to fit needed for odor control. I've done some research and keep coming up confused because I'm getting different cfm's. My tent is currently 5x9x6 (5...

So I've been growing 1 plant at a time in a DIY cabinet with CFLs and a 100 watt LED for flowering, and it has been working great but I asked a mate of mine to bring me a tent on his next trip home so that I can grow non-Autoflowering strains and SCROG the one plant for max yield. The tent is...

Hi there, I'm looking to start a new grow soon but I am having trouble finding the correct requirements for my situation. My 2x4x5' tent will be in my basement, near a window which will be ducted to the exhaust. It is imperative that this be an odorless setup, therefore I need to have the...

Ok so I'm going to have a medium size grow (on the low end of the spectrum though) of 30 lights (1000w.) I have way more space than I would ever need for any theoretically sized grow I could conjure, but for the moment I'm building a contained room within the space itself of approximately...

I'm in the process of setting up a dedicated drying tent. I'm planning on a 32"x32"x63" tent. Gonna keep the vent flaps open and throw a 4" inline fan up top to get some airflow. Question is, what cfm inline fan should I get? Or should I get a duct booster...something weaker. I have my eyes on a...

Hello everyone, I'm planning to grow 4 plants in a grow tent "Grow Lab GL80" (size is 2'7" x 2'7"x 5'11"). I have 3 questions for you, colleagues: What pot size should I use to grow 4 plants (2 sativas and 2 hybrids) in the aforesaid grow tent? Should I use 400w or 600w HPS bulb to fully cover...

hello my riu dudes, Hope the week is going swell. As you can see from the title, I've got a 4x6x6 grow space and I've the calculated the volume and it's only 144 sqft. The fact that the carbon filter will cut down on the efficiency of the fan makes me want to lean towards at 400 cfm fan/carbon...

Hey guys; I'm new to growing and i'm about half way though building my very own grow room! So excited! However i have no idea what fans i should get, I'm tight on money and i was hoping i can cheap out on exhaust fans, but using the very best carbon filter, lights, ETC. The Grow room is the...

hi I am in need of a *preferably silent* circulation fan suitable for an indoor grow tent so that I can breeze everywhere in the tent. I think I need an oscillating one, but not sure how I would secure that to function in my tent. my area is 8 sqft. i also plan to upgrade the exhaust fan, and...

So I have ×2 250cfm 150 Cfm airflow I believe it said. One pushes one pull on either end. I'm getting an air cooled hood and filter. It a negative pressure set up. Pull through the filter-hood-fan#1-about 20' of ducting-and out of the building. So now for the question how do I figure out what...

I have both an intake and exhaust fan. Should they both be set to the same speed, or should one be pushing more air than the other?

Alright, I had a question regarding what size fan and filter I should go with. My tent is 3' x 3' x 6'11, I'll be growing, at most, 6 plants. The reflector I have is air cooled. It accommodates an 8 inch inline fan. So I'll have ducting that is dedicated to just pushing air over the reflector...
