C02 Calculator ~ Calculate How Long to Run your CO2 Tank

I have 20KG bottle

I put my bottle on the scale and see how much g or kg have release to the air. How can i calculate how much do i need for Grow room area: 700 cubic feet (in grams or pounds ...)

Grow room area: 700 cubic feet
Amount of CO2 required: 0.84 cubic feet <- How much is this in grams ?

All right i solve this problem:

Grow room area: 700 cubic feet
Amount of CO2 required: 0.84 cubic feet = 23.7861 L = 47g(15°C)


1,847Kg (co2) (15°C) = 0,9344m³ (934.4L)
1,977Kg (co2) (0°C) = 1m³ (1000L)

I make homemade wine and was gonna put my wine in same room as plants any idea how to calculate the C02 from 5 gals wine over time it would need to be replaced about every two weeks as it slows down alot after about a week or so . Im kinda getto and a cheapskate so its ye old killing two birds with one stone trick works for me

Just curious how most people get their c02??? Is anyone renting c02 tanks from welding supply stores? Any problems doing this??

has anybody ever tried enriching the roots with oxygen, the way we use co2 for the air?

Its called Hydrogen Peroxide....H202...Its water with an extra oxygen molecule. You can buy it at any hydro shop.

This thread is very helpful but I have a question.
Why put so much effort and money into this?

I think it would be cheaper to get the $180 indoor air meter and dial in a custom made Co2 maker.

Simply take a bucket of water with baking soda in it and attach a distilled vinegar bottle like a hospital IV would use.

I think I could make a generator for roughly $20 or less. The vinegar and backing soda cost is negligible because at the end of the day it's cheaper than a tank, regulator, timer, and refills. So for $200 you make a generator for CO2 and have a meter that will allow you to fine tune your drip rate.

Sure it's more work you'd have to do, replace the water and vinegar every 2 to 3 days, but compared to the cost of buying CO2 from someone I'd rather take the 3 - 5 minutes of work. Not to mention eventually someone is going to wonder why the your buying 60 - 80 lbs of CO2 every 3 - 4 weeks.

at what ppm is co2 deadly to humans its it ok to sleep in the same room with co2 running on a timer?

I'm curious about "environmental controllers." They regulate the amount of CO2 in the air, even when the exhaust fan is on. What good is that? How do you keep a high level with that thing exchanging the room air so often? Seems like it would be more effective to put the exhaust and the CO2 on separate timers so that when one is on, the other is off. This only allows your room to saturate for a short period of time, but it's better than pumping the room full constantly?

With environmental control units you can set them so they will turn off exhaust or other appliances when C02 kicks in......thats why people invest in environmental control units, they make life easy.

You could do the same thing with a lot of calculations for time, and a shit load of timers for everything, but with a control unit it does all that for you.

controls are just the way to go(high end)..

Unfortunately, not everyone can or will make the investment to simplify procedures.

Save up money...

Just wondering if anybody has any info on co2 burners, I cant seem to find anything that tells me who makes it or CFH. How would I find out this stuff?
I also have FHD co2 monitor and controller that didnt come with an instruction manual.

Maybe the very high end controllers do that? The $250 model doesn't, as far as I can tell.

I don't see anything that says it will soak the room only when the fans are off?

For $650, this one does it all (I think) http://www.htgsupply.com/viewproduct.asp?productID=50152

But that's a lot of bread to replace $50 worth of timers.

The idea of the control unit is you dont need to calculate times for multiple timers, you have somthing to do that for you.

No one said they are cheap, nothing is cheap that makes life that much easier. If you ever get your hands on a high end controller you will understand and wonder how you ever grew without it.

If you actually read that one you posted, it can control heat, humidity and c02.

It doesnt have to say "soak the room when fans are off" thats what the unit does, it disables one thing while turning on something else.... How you use it is up to you.

thanks for the info! Which model do you use? I would love to get the $650 model, but I need to stick to a budget for the next few months. Is the cheaper one even worth it?

It all depends how many fans, and how many appliances your trying to run on the unit.

That $250 unit would be great for someone who has 1-2 1000w lights with an AC, exhaust fans, and C02 system.

That would be me to a T Thanks.

I would throw you some REP if I could find the button?

The new layout has issues, you cant rep. Go to My Rollitup and scroll to the bottom of the page and switch the template layout to Blazn07. The old layout works way better.

This is really nice, Thanks.

I just bought that c02 setup off that link but also a good calculator.
