Thank you. Very helpful video. Im now a Subscriber!

thank you, very helpful!

I don't have a "grow room" but last year I grew a few plants, very successfully for my own use, in my 10 X10 basement room completely sealed off to everything except the entry door to access the room, no windows no vents, etc, all concrete. I had an LED grow light, a dehumidifier and a box fan with a charcoal filter mated to it for odor control and another box fan for air circulation. The only time I would go in was when I watered. Grow light was remote controlled. It was surprisingly simple although I had some fights with soil gnats and some powdery mildew but the end product was excellent. The only fail was odor control, especially during flowering. I'm trying to decide if a stand alone fan and filter(similar to what people use in a grow tent) would work vs a reasonably sized(???) ozone generator. The ozone generator is tempting. On the other hand, I might be able to create negative pressure with a fan/filter. Any advice would be appreciated.

Wow, I have been looking and looking and your vid is one of the first I have come across that explains this so well. Thank you! What would you consider good for venting 2 4x4's and my only concern is odor control since the smells make him nauseous. I am currently using a vivosun 6" fan but my tent is a bubble lol. I know it pulls plenty of air into this from via the tent, from the rest of my house because you can feel the air that rushes in from under the door (2 " crack at bottom for air exchange).

Nice video. What is proper ventilation for a 5x5 tent grow with a 730W LED in a room with 10,000 BTU window AC? The house has central air. Half the window AC will be routed into the tent for a constant supply of cool air. Should I exhaust the tent out the window, in another part of the house, or in the same room ? 2 in-line fans, one for intake, one for exhaust or just one for exhaust that’ll pull air into the tent too ? Thank you!

Would a small 600x600mmx1650mm high tent work with a filter and ext fan up top of tent, and re-routed to bottom of tent, with a small exhale bag hanging low. kind of like a closed loop circuit. so there would be no in take of fresh air (other then when I open tent to water). But there is a small oscillating fan running. Temp of tent is controlled via the room temp. Thanks

Using a extractor that can pull 700m³/h, can i use only passive intake or should i use passive and active intake. How big does the intake hole have to be for 700m/³ or what is the lowest m³/h i can activly put in so it has good pressure inside the grow.

hi. i have an oid unused carbon filter. is it usable after about 7 yrs of being in a sometimes damp English garage

Can someone answer me this . Is it better to have 2 exhaust fans or 1 with the equivalent cfm3? I’m considering buying either 2 at 1400cfm each or 1 at 2800cfm , I wanted just the one but realised it would be much heavier to install but then I started wondering if I had 2 they Would possibly fight against each other?

How well do the carbon filter work to eliminate Oder?

can I grow cannibus in my garage where the temp is likely to exceed 100 deg. farenheight.

At the 1min 45sec you have some sort of filter with a draw string? What exactly is that you're using? I'm not wanting to use pantyhose

I pulled out my charcoal canister with seven large plants in a 4 by 8 and had zero smell from it the only smell I'm getting is now that I've harvested a week and a half later now they're smelling but nothing came out of the tent as far as funky smell goes. Save myself $180 on a new filter

Is there a way to have the filter and fan outside of the tent, pulling air out as opposed to sucking air into the filter? In order to free up room inside the tent... If so, please do a video demonstrating this🙏

i love my box fans

When should you start using the air system?

I was wondering how could this set up be as it looks like a closed system with no relation to the room itsel. It looks like it sucks the air from outside and move through itself and then back out. I would think. there should be two separate set up. One blowing air into the room. And another completely different set up at the other side of the room blowing air out. What I like to see exactly the part that the air actually enters the room, not the part that is outside the room, that is obvious. Then I like to see the part that the air from the room enters and is pushed out, not the part that is outside the room. You can't have the blowing in and blowing out next to each other.. I don't get it.

I am a firm believer in push-and-pull. meaning, add an intake fan the same size as the outtake fan and adjust with speed controllers to get your balance.

If I keep my tent in room. And keep extracted air in the room. Whats the point of extractor? If we are using leds and temps are fine?

To anyone starting out, we all know funds can be tight BUT........... never ever try save money on your extraction!. Cheaper filters in my opinion are not very good at all, always try save money elsewhere to go for a better brand extraction filter. At the end of the day it’s for YOUR safety and you risk everything by trying to save afew quid. BTW the carbo air filters in this vid are 👌👌, these will last you a sold 2/3 years

You do not need a fan that strong for a room that small. Do the math, your fan should move SLIGHTLY more than your rooms total square footage.

Lost me at the metric system

I don't think you know what you're talking about.pump the CO2 out. what are you talking people pump CO2 in...next
