CO2 release method

So i read the Co2 calculator... and my Co2 method is going to be a little more unconventional. I was recently down in my basement where I found a 15 gal c02 tank thats full. Its just the tank, nothing more. I figure to release it Ill just give a burst into the grow room. My question is, how often should I add co2, and how long of a burst should I do? I dont have a PPM reader, nor do I have the means to purchase one. Hell, I dont even have a ph meter (but im getting one soon).

Any advice would be appreciated!

Also, my plants are in early veg right now. Would I be better off to wait until theyre flowering to use the co2?

And my room is a crawl space in an attic, im only using a small area of it. Its like 4ft wide by 5ft high by 15ft long. Will the C02 completely disperse in the room, making it pointless to release?

anyone?

You'll get the most benefit from CO2 supplementation by using it during the flowering phase. And then only use it when the lights are on. Without a regulator and proper metering equipment, I have no idea how long you should keep the valve open. Generally, the air in a well-ventilated room has a CO2 concentration of about 300ppm. With supplementation, you want to increase that up to about 1500ppm. But again, without a meter, regulator, and controller this is a totally hip-shot scenario.

Well Senior I dont think people replied back cause they wanna say something that could give a bad outcome (health reasons IMO) keep in mind you breathe o2 not Co2, being in a room while spraying it with Co2 wouldn't be the best idea, cough up $80 go on ebay and get a regulator kit for it. Or just make some home made Co2.

Thanks for the info. I guess Ill just "wing it" when that time comes.

If i need to increase the amount of C02 in the air by 5x, it would be relatively difficult to put TOO much in, so I should be safe with like a burst a day.

Just popping open a CO2 bottle every once in a while will work. But its ALL guess work. Pressure and flow rate matter as do the room and plant size.

And a 15gal bottle? Not too likely. 10LB 20LB makes more sense.

CO2 sold be used while lights are on only.
CO2 *should* be regulated/controlled to 1500ppm

A few quick blasts during the day will help, but........
And if you are going to do that, at least get a pressure regulator. Dumping the CO2 out at near 900psi, makes it even more uncontrollable.

You could also go get a bag of balloons and poke a pin hole in it before filling it up. Put that in the room to slowly release the CO2. Do that a few times a day.

But a solenoid vave controlled by a ppm meter is the best route.

(CO2 is the last thing one should add to a grow. Get a few successful grows down first to see if the CO2 makes a diff)

i have heard that you can mix yeast and sugar into water and it creates co2. i mixed it up in a 2 liter and leave it in my room shaking and adding sugar occasionally to the bottle. i don't know how much of a difference it makes, i almost feel like your better off spending time with them and talking to them

The yeast and water doesnt really do anything.
