Suggest me automatic CO2 system.

[TheHero]

Hello.
I am going to "do" a sealed grow room setup. I have found that I can buy a 10L CO2 tank, here, where I live. It has 21.82mm metric type thread.
I would like to buy a system, so I can adjust CO2 ppm as much as I want.
Aprox. how long would 10L (7kg) CO2 last running 1500ppm? I could turn off system before dark time.

if your room is the size of a porta potty it will last ....a long time.
Some spaces would require more than this amount to reach 1500ppm for one minute.
do you see how many variables there could be when trying to answer your q?

try this when you can fill in the blanks, I found it on google

Oh, snap, I forgot to add size of my room, it is around 1.7x1.7x1.7 meters

Ive been using thier co controller for 3 yr, lighting timer 5, no problems.

Ok, how is it controlling co2 flow? By a electromagnetic valve near co2 tank?

 

[Millsie]

I remember Growmau5 was messing with using a gas/lpg hot water system to heat up minute amounts of water & funneling the flue into the room..

 

[chemphlegm]

no

 

[TheHero]

What about calibrating those things?

Just looked at atlas 2 co2 controller. Its written on it 120V 15amps. wtf is this?

I found on amazon this "
CO2Meter RAD-0501 Day Night CO2 Monitor and Controller for Greenhouses".

I cannot post link, because I am a new member here. Check this controller out, looks good?

I would read that as the device pulls 15amps (current) and runs on 120v (volts), but that seems like heck of juice for a controller.

More likely its saying you can run this on a 120v / 15a circuit, which is typical power at the wall in US.

I have the Atlas 2 and it is a preset unit meaning it will run the CO2 regulator until the room has reached the preset saturation of 1500ppm. You have no control over this unless you're nifty at opening things up and reprogramming, which doesn't appear likely.

I wonder, how much power that electromagnetic valve takes (that opens gas near tank).
So, atlas 2 has only one setting at 1500ppm?

Yep

 

[TheHero]

Yep

Do you feel any higher electric bill from that valve, that opens a gas tank?
If I do not need more or less than 1500ppm, why would I buy atlas 3?
When You will exchange your co2 tank, could you check the size of thread on tank? We have a standart here 21.82mm I guess..
