carbon

I am new to growing and I'm just wondering am I supposed to have the carbon filter and fan on during the veg stage or the flower stage or both I would appreciate any help thank you

Can I have your opinions on my new 4 inch fan please? I bought this off fleabay after the seller told me it would be fine to attach ducting to both ends. Of course when I unpacked it the power cable looks like it'll get completely in the way of any ducting! Do you know if there's any way around...

(( Pics at bottom )) Hi All, Almost too much info on this site. Thanks in advance to everyone that at one point answered someone elses random questions to reference and get my build off the ground. First my requirements were absolute stealth. No exceptions. Plus to hide this it needed to be...

Hi there, Dumb question. I tried googling for this but couldn't find any info. Apart from growing the herb, why else would someone need a carbon filter? Is it not obvious to every hydroponics store owner that when a person comes in and buys a carbon filter, they are growing...

I've been kicking the idea around about using aquarium activated carbon in my next mix of soil later down the road. I've read some benifits to adding coal to soil related to gardening. So I'm curious if anyone else has tried it & has wisdom to share. In my current grow I mixed some carbon into...

Hello, I'm new to the forums and have a pretty big issue. My boss gave me the opportunity to live in a really nice house. However the catch was, that the entire basement was a grow OP. All of it is for medical purposes and perfectly legal. He told me at first there would be times the entire...

Hello everyone. I know, the smell, it's nice, it's great. But if you need to hide it and do not have the money for some nice and shiny carbon filter, you can get inspiration from mine- ugly and not so shiny- but definitely working one. It has very low drag and I have tested it with strong...

I really didn't want to deal with any ducting inside or outside of my tent. My plan was to simply attach the fan to the carbon filter and then have it vertical exhausting through the top vent. But now I'm thinking that won't work. Most videos and setups I see has the carbon filter and fan...

Hey guys, I'm new to the forum here, and am looking for some advice on the best ways to store my carbon filter in between grows. Depending on the season, the area I live in can get REALLY humid , 95%+ relative humidity, where water condenses on the walls without a dehumidifier. How...

Anyone using one of these CF brands? - Max Carbon Filters - Carbon Active - Can Filters - Prima Klima I'd like to know if any of the above mentioned are good.

I won't be able to purchase one for a while, but does anyone know of a cheap(!) fan or blower that can move at least 270 CFM through the restriction of a carbon filter and moderate associated ducting? 6" or 4" only, please. Thanks!

Hey guys! Just wondering if anyone knows where I can get a Pre-filter replacement for my 6" VenTech Carbon Filter? I'm in Canada too so would prefer a Canadian website.

Pot brownie meet the Cannabis Car. A Key West man has become the latest, though not the first, to extol another wonder of the miracle plant: a car mostly made of hemp that he says can cut the carbon footprint of the planet's estimated 1 billion cars and cover much-needed ground in the fight...

Hey everyone one my carbon filter came off the other day, i can see little black carbon on some of the plants so i used my spray bottle to get some of the carbon off i know misting in flowering stage is bad (Bud Rot) but in 5-10 min after spraying water it drys out fast so I'm not too worry ya...

Hello, with HPS lamps, I red that the airflow needed for a growbox with carbon filter in cubicmetres/h should be about the same as the power consumption of the lamp. But how is it with LED panels? Obviously they need less but how much? Specifically: a 60x60x140cm Growbox with a Mars reflector...

Ok so going to be doing a grow of 6 plants, in a tent that is 1mx1mx2m. however i am a bit confused on which size of extractor, inline, and carbon filter i should be using. there are 4" setups, and 5" setups and obviously much bigger ones. which one should i go for to ensure smell is...

Hello, Im planning on starting my first grow in 2-3 weeks tops but before i start growing i want to have the smell UNDER control. So I was thinking about setting up my CF and Ex fan inside my growroom, but have the duct right next to my window (Thinking about building something that would allow...

I think I've narrowed down how I'm going to set up my grow room... probably using Cap'ns design. I realize that the odour produced by a ripening flowering room can be pretty strong. (That's what caused my forced vacation 20 years ago!) So, I'm very interested in getting the best odour control...

Researchers at the University of Alberta's National Institute for Nanotechnology (NINT) have discovered that hemp based electrodes for supercapacitors outperform standard supercapacitors by nearly 200%. At present, the preferred material for making electrodes is graphene. Electrodes are what...
