co2

Yah a carbon filter. I have a seperat fan for a fresh air intake. The i have a carbon filter hooked up the an inline fan that pulls the room air threw the filter pushing that air flow threw my hoods into the next room used to veg.

He's a "boyfriend" thats what she gets for going out with boys . gotta get her a man

If you took the carbon filter off the fan that feeds to the veg room and just let it run in the room and hook the intake fan through your hood so that will move the air to the veg room then you will have a closed environment and be able to use the Co2 system you have.
Problem solved

Just tell boyfriend to man up and GTF to work

at least Your vegging plants are getting co2

Ok just one last this. With the set up i have i did check the co2 levels and it was at 1200 i tested with the co2 tubes that u push an air sample threw. So since i am exhausting the co2 out how can the room read 1200?

Well theres mechanics that come into play. If its a cheap inline fan like a $20 one then most likely its a passive inline fan, those are usually used in where theres alot of ducting (in grow rooms and air conditioning and what not.) and they attach those into the middle or other areas of the ducting to help move air but they are not the stronger expensive ones that push the air. Keeping that in mind along with Co2 being heavy and having that carbon filter connected to the outvent which is also gonna hinder the fans power to exhaust. That could by why the room still has a high co2 level, but its just a guess


What kind of filter is it by chance? How much CFM does the fan push?

 

[Tiffay2180]

Its not a booster fan its a six inch inline cant remeber the cfm but over 5 hundred

 

[Tiffay2180]

How close to the plants should i have my tubing?

I use co2 in flower only, I didnt notice a big enough difference to use it in veg. I only really started using it because the temps in my sealed room ( spare bedroom using Central AC ) would get up to 85 degrees with 2000W

I get higher yields running a sealed room with co2 (1500 ppm) at 85 degrees than I did at 75. With high levels of co2, they seem to do better with a little more heat.
