"Air flow meters manufacturers hate him. Do this one weird trick in your grow room to... " ;)

[@goonernumone8444]

Ive removed as much of that ducting as poss from my room, buying 5 inch solid duct and a 90 degree bend, the best thing apart from improved airflow was the reduction in noise, i cant believe people with designated "rooms" actually use this ducting and not solid pipe and bends they are not even expensive

[@sealsept]

Kinks, bends, pinches, along with the spiral vent tube all contribute greatly to what is known as “shock loss” in underground mining ventilation technologist speak. I breathed the air underground for 42 years. Smooth solid tubing, minimal bends.

[@CrownBar]

I’ve got a silencer attached to my fan. Not impressed with the air flow if I’m honest. I wonder if the silencer is having a negative affect due to it being much wider than the fan

[@MinesanityServer]

Oh wow. Awesome test Shane! Haven't seen an in-depth air flow video like this anywhere, thanks for the info!

[@truescotsman4103]

i use a forced air system rather than pulling air from the system. pulling air allows dust, insects and pathogens like mold to be drawn into the grow. I use a filter box i built myself that uses an AC grille and a typical 20x20x1 air conditioner filter. the box in acoustically insulated with cloth interior. the box reduces noise about 60% and prevents mold, dust and insects from being drawn into the airstream and contaminating the grow. if you're using a filter simply place your filter on your outlet and force air into the enclosure and your escaping air will flow through the filter while at the same time giving you the protection of a forced air system. ive had great success with isolated environments controlling insects and mold because this system is preventative and works very well at keeping things you don't want outside your grow.

[@glockasauruswrex6362]

great stuff! I really like your channel...as a new grower your videos help fit the pieces of this puzzle together for me! Thank you.

[@vinylpop]

Great video. That’s an AC Infinity fan, correct? I just set one up in a 4x4 tent. My first indoor setup. My question: do you recommend setting the fan to auto mode, where the fan might shut off when optimal conditions are met, or do you recommend leaving it on 24/7 to control odor and air flow? Thanks

[@ExploitTheVibe369]

I would do a calculation of the weight and potential energy of the card. ΔPEg = mgh for distance or lift of the card to angle of the lift. And calculate if the box is level and humidity, elevation and air pressure to determine those variables... I like your box way better than thinking about it even doing those calculations!

[@atomizer2665]

Make yourself a simple manometer using a length of clear aquarium air line. Measure the pressure in the duct (inches of water column) and you can figure out how much airflow you are getting from the fan curve/graph provided by the fan manufacturer. You can also use the manometer to check if alterations to the ductwork have made it better or worse. The fan`s maximum flow will be at 0" wc, which is when its not connected to a duct.

[@drgrowuk8830]

Absolutely brilliant video 👏👏👏 So simple but so effective 👍 brilliant

[@torrencekrepps757]

I'm a new grower sir and I truly have a good question I have a 4x8x7 with 2-K4000 Aglex and my air system is an 8 inch vac. Hooked in the tent and I'm worried that it's to much and someone said that I would have to watch so that it doesn't suck my turpines out if it's to strong

[@posiomoot4043]

Can you please test the Spder Farmer SP 1000/2000/4000, there are no good tests for this lamp in the internet

[@ryanpongracz8051]

I own the spider farmer 4000 and it's going ok so far, will update when I crop out.

[@Fubared4201]

Yup same here I have 3 fluency spider 2i and the spider farmer 4000 works prolly just as good as the fluency so far 👌

[@PopeDPG]

Shane ive heard a few people say not to use these in grows bc it kills terpenes falavanoida and im wondering...i want my harvest to be nice and lovely full of terps and flavs sooooo what do u think ? Maybe an idea for a video too. 1 tent uses carbon filter 1 doesn't

[@andethidialbubabibub3261]

Not rly what I was looking for but that box is genius

[@afro208]

The walls of the tent are a great airflow meter. They suck in slightly, job done.

[@dionfosterandkids]

slighty lol. ive just set up a 2x4 with a 700m/h 150mm centrafugal (yeah over kill but it works great) poor tent lools like its hooked up to a vac pac machine when fan is on

[@Arrgh]

All i can think right now is a sound level... Optimizing flow with lowest sound print posible. Thx Shane!

[@dallimamma]

ivan buntic ::: Use metal pipe for best soundproofing, and airflow.

[@stevenstreefkerk2510]

Good day Guys. I want to run my extraction fans hot air into tubes that will sit half a foot above my reservare floor. I want to utilize the warm air to agitate (oxygenate) the reservare. Do you think it could work? Would it put to much pressure on the extraction fan? Would love to hear your thoughts. Thanks for the cool video!

[@jaimedelgado7529]

You're the real MVP Shane ! if you're ever in south portugal hit me up. I'll show you how the sausage is made and we can have a session. (*pause*) that sounded gay ! what I meant is I'll show up my setup and give up a taste. .....of my microgreens 😅

[@robertmiller6822]

I suppose an intake fan would also effect this only thinking this cause my tent is usually a tiny bit puffed out in stead of sucked in but yeah awesome idea Shane.

[@baileyrock2436]

Great video, love how resourceful you are, thanks for all the other videos you make too. Outstanding

[@JohnWick-id6pk]

First of all it is recommended to use a RVK fan instead of an inline duct fan when using a carbon filter

[@JohnWick-id6pk]

@Flora Nugs, No, he's not using a RVK fan which is designed for extraction of air. These don't have the same purpose. Like static pressure fans and airflow fans, you could use one as the other but performance won't be the same. @Andy Moore, First of all meaning, if you want to improve your grow room ventilation this is the first thing to do.

[@JohnWick-id6pk]

@Andy Moore Well I was just stating the obvious, I thought it was common knowledge among growers (it is on french forums anyway) to use inline duct fans as intake and RVKs as extraction if using a carbon filter, like the thumbnail Shane put for this video, because inline duct fans don't produce enough pressure for the carbon filter suctioning and it results in the grow tent odor extraction and airflow won't be good enough even if rated as the same "flow rate" (like 300m³/h).

[@manbunmyname5866]

@@JohnWick-id6pk You're a prick, just stating the obvious.. it's common knowledge.

[@JohnWick-id6pk]

@Manbun Myname It makes me a prick to explain simple stuff to people who delete their messages after they have been confirmed wrong by what I said ? What is wrong with you ?

[@JohnWick-id6pk]

@M P As I said, the design is made for intake or extracting air but not in this high air resistance setup (the carbon filter). Nor the performance or the longevity will be on par with an RVK fan which is purposely made for this scenario. Design in the inside (and outside as you mentioned) are absolutely not the same. Inline duct fans are made from typical fan blades whereas RVKs have centrifugal fans. This is why it is best suited for this task. Also, RVKs are not always metal, Systemair and Prima Klima models for example are mostly plastic and are not worse than their metal counterpart. Please don't be butt hurt if I criticize your setup

[@rickybbuffalo706]

Awesome video man. I have a question about stacking a pot on top of another 5 gallon felt pot Will that increase root depth?

[@MK-zf9wh]

Would have been interesting to see normal ducting Vs manrose rigid ducting, same length size and bends

[@midniight]

If it's cold can you recycle the air coming from your filter back into your tent?

[@MIGROLIGHT]

Hi, You will see a spike in humidity doing this unless you run a good dehumidifier

[@skoski5860]

what did you tape on the box to measure the flow?(the little flappy bit)am sure that matters as if you was to use maybe a bit of paper then surly the flow would always be at 10 no matter how high or low you have it i only ask as i noticed it was thinner then the cardboard box itself :) and of course if you was to use something heavier then cardboard the reading would be lower.i am going to try this i just want to make sure i dont mess it up lol Great video btw :)

[@MIGROLIGHT]

It was part of the box stuck with adhesive tape

[@scottarnold6528]

Do you have a filter cloth inside your Charcoal filter to help protect your fan & prevent the filter from dusting your room with activated charcoal?

[@teej7577]

You can use an Intake Filter or Filter Box from Fine Mesh up to the Standards of purification you want with Hepa Graded Materials..A Carbon Filter can strip too much of required or Beneficial components From the Air before it gets to the Plants..some Good Products out there if you look around..Phat Intake filters,..the coolest is the Dustroom Filter..I Made my own from seperate Purchases of Hepa Graded Materials and Filters..but i saw an inline box for sale at a good price and got one the other day..lol

[@jblazer2492]

3:37 So there you go! Were getting a reading! xD Genious!

[@silverstone78]

You could order a 8$ airflow meter from ali and it would work just fine.... I made a small hole in the door to my grow and a mount for a china airflow meter. It gives me an indication of the passive airintake in the room ... i can then monitor air intake from my adjustable intakes or the total outtake in the room. i run 2 filtered prima klimas and one go out the house and another goes into the next room saving heat.

EXCELLENT HACK! EXCELLENT INFO! I DON'T EVEN NEED TO TEST NOW! I ASSUMED THAT WITH 5-6M OF DUCTING, I'D LOSE AROUND 50% THAN VERY LITTLE, OR NO DUCTING AT ALL. YOUR VIDEO IS EXTREMELY HELPFUL! I'VE HEARD/READ THINGS. BUT YOU ALWAYS SHOW US! I'D BE VERY CONFUSED ABOUT MANY THINGS, BUT SEEING IS BELIEVING! OH, F'K QUANTUM BOARDS! MY CHEAP, OLD, CITIZEN COB's AT 100W(120W USED?) WORKS BETTER THAN 200W OF HLG QUANTUM BOARDS IN A 32"X32" TENT. I BELIEVE MUCH HAS TO DO WITH THE 90° LENS ON THE COB'S.. BUT MUCH MORE STRETCHING IN VEG. RIGHT TO THE SURFACE OF THE BOARDS ALMOST? VERY STRANGE? MAYBE THE Q.B. SPREAD OUT 180°? NO LENS. MORE EFFICIENT! BUT BAD RESULTS WITH QUANTUM BOARDS FROM ME. LEX BLAZER MENTIONED THIS, BUT SHANE IS A GODSEND! ALWAYS AHEAD OF OTHERS!!!

[@robertthrem3382]

That's all good if you have an apartment but I would say if you have a house you can use like a furnace chimney to particular one I have in mind is called the bazooka it has the air in and it has the air out coming out of the same pipe you should research that and make a video

[@rifsundergroundgrowmie2603]

What if I'm using CO2 tanks is there a way that I can save it instead of sucking it right out maybe some kind of recirculating system?? So it would suck it into the filter scrub it and push it right back into my tent can you please help me with maybe trying to figure something out do not waste my CO2
