ventilation

Background Info: We moved into a new house that has a walk-in closet in a spare room with a continuous passive ventilation system built into it. Something sort of like this. The builder explained it's to help with ventilation in modern homes that are sealed up better than older ones. There are a...

Does anyone know of or seen a type of powerless turbine vent? I'm running a passive intake and using the lower intake vent hole to pull the air in. I'd like to have a sort of duct tube that has a fan blade in it that can be ran off of the vacuum of the exhaust to help distribute fresh air...

Hey guys, long time reader first time posting. I am currently building out a spare bedroom I have to fit two growers choice 680 LEDs. The room is approximately 10x15 ft. I will be using the central air to cool the room but the problem I have is the dehumidifier in the room gets too hot (85-90)...

Hello, my room has a wall unit a/c under the window and I am growing in a tent that I am going to be exhausting out the window. My question is it suspicious that I have an exhaust vent in my window when there is a wall unit right under it? Or is it reasonable for landlord( if by chance he see...

Hey! Cutting a story short, I've lost access to my grow space. Unfortunately, being in rented accomodation, I can't set up a proper sized grow, so I've got to either NOT grow, or get a small discreet grow going. I definitely would rather choose the latter (obviously, right?) But I have no idea...

I'm setting up a new tent because I won a monster of a light( thank you @MedicGrow, loving the #Ez8.)So I bought a larger inline fan(6" vivosun) for the bigger tent(4x4) and even on the lowest setting the strain on the fabric of the tent is significant. How bad of an idea would it be to vent...

So my question is in regard to my inline exhaust fan. I'm ultimately trying to determine how long I need to run it each day, if at all. I have a table fan feeding fresh air in the tent from my room, and I have an oscillating fan inside the tent. With the help of a humidifier, while running the...

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...

What's up Rollitup!?!? I am in the planning stages of a grow operation I would like to set up in the attic of a place I plan to live for the next several years. I want to do this right, and hope to set something up once that I can rely on for years to come. I have a little experience from...

I’m fairly new to growing, and I need some help from other fellow growers as I’m in a situation I cannot figure out myself. I have set up almost everything for my hydroponic setup; 600w led light, t6 cloudline, a couple fans as well as a filter. Unfortunately no matter how excited I am to grow...

I posted a couple of pics of my tent. Should I be putting my duct through the top, the side, etc? And how would you suggest I vent the seedling side that’s blocked from the rest of the grow tent? Thanks in advance!

First grow everyone, so I apologize if any of this information is excess or if I'm doin anything obviously wrong I knew I was going to be running into a few issues, these are are unfeminized bagseed so I'm really just doing a trial run before I get some real seeds. I started these seeds before...

Hi guys I'm looking to start growing 2 autos in a DIY 160 x 40 x 40cm grow tent. Everything is starting to take shape in my head, the trickiest part seems to be the ventiltion. I've done some research but i'd like to hear from people who've actually done it. How strong of an inline fan would I...

Good Day. I am a new grower, this is my 1st attempt. I am growing 2 autoflowers in a 2'x4'x5' tent. I am using an AC Infinity Cloudnine T4 inline fan (205 CFM) w/ an AC Infinity charcoal filter. I was planning to purchase a 2nd AC Infinity filter to have as a back up or to even use in a tent for...

Guys, thanks in advance! This is my first post on here and I'm on my second grow ever. I just upgraded from 2x 300w viparspectra to a MarsHydro TLS2000W grow light. I thought that this was supposed to produce a lot less heat but I still can't keep my tent under 80 degrees. It's indoors and the...

Hello friends pls help someone with expirience :) I'm doing cloeset grow : Light is SF2000 with 100mm Prima Klima extraction fan (280 m3/h) with speed controler and carbon filter, so my question is: *Can i put 120mm PC fan something like "Noctua" for my air intake will that be enough for...

Okay, probably a stupid question. Buuut, if I put a 6 inch fan with a filter on it on a 4 inch PVC pipe about ten ft long, would I be able to get slightly more cfm through it than with the 4 inch fan? I'll have an 11x6x80" room with two 3x3s in it, they will have a 4 inch fan and filter pulling...

Hi everyone! I'm about to start my first ever grow. I have zero experience, very little knowledge and so so many questions. I will work on a diy tent 60*70*120 cm (23*27*47 inches), the tent will be in my bedroom's closet. Is my tent considered a micro one or not? I have trouble deciding what...
