CO2 - how to?

[turtle420]

Im not sure about what turtle was saying about 1500PPM killing you, he could be right, but i know that your little mixture wont produce that much CO2 anyways.

Yeah, I searched, and toxic levels of CO2 are 200,000 ppm. So please, Sativagrowing and everybody else can feel free to stick their heads inside their grow rooms when the CO2 is @ 1800ppm...

:stoned: turtle knows ok ,hes the man ,hahahahah ,well done turtle:stoned:

[shiloh]

what is "ppm"? how do you measure those number? thanks

They have meters to test ppm. The paintball CO2 tank you saw is a CO2 tank just in a smaller size. Because of how small it is, I'd suggest you not getting one of those and instead getting a scuba sized tank. You can probably find places to fill your tanks around local stores. Paintball stores, usually a sporting goods store, and maybe a hydroponics store. Hell, even home depot or Lowes might fill them (haven't checked). Goodluck.

Or kill your self... CO2 is odorless, and colorless... you won't see it... the 1500ppm levels we where talking about, are absolutely DEADLY to humans... and dogs... and cats...

Remeber: SAFETY FIRST!

ummm... thats a joke right?? :rasta:

OSHA says you can work for 8 hours in some crap like 60,000 ppm... it wont kill you unless you suffocate yourself with it... ie - no more oxygen.

to my knowledge you cant buy bottled up deadly gas... or we'd have a bunch of mini-hitlers running around using them.

you CAN use sodium-free seltzer water as co2 - there is actually a lot of CO2 in 1 bottle... you want to mist the UNDERSIDE of all of the leaves... it actually helps - they recommend 3x a day if thats your method, but 1x a day, right at lights on works well IMO. it must be sodium free... it should just be carbonated water.

i know a lot of ppl use the cheap-o method of makin' co2 with the yeast and all - but IMO tanks are the only way to go... you get dependable co2 thats always working, and a GAUGE tells you when you need more.. you dont have to stick your head in a bucket and see how much you yack to tell if your co2 is workin.

I fill mine at a welding gas supply store. It costs me $15 to fill up a 20 pound tank. The tank usually lasts between 1 and 2 months.

Yeah dude, I searched... I stand corrected.

Still, you don't think it's the White Collar engineers that work @ 60,000ppm... ? do you?

Will it kill you? No. I was wrong.

Will you enjoy it?

He corrected himself.

Also, not everone has $140 to pay for a guage to connect to a tank (especially when you can get a propane CO2 generater for a little over twice the price). The method I posted is good for the people looking to experiment with CO2 addition to their gardens or to people with a low budget. Goodluck <3

tru man - i wasnt tryin' to sound like an ass... sorry if I did.

I'd like to see someone do the yeast method with a ppm meter... even though those cost more than the regulators

i dont even have co2 yet - but i've been looking at it... I have 2 problems with the generators... 1 - they make heat, which i'm actively trying to get rid of... and 2 - there is an open flame in my grow room - i would just be worried about comming home to firetrucks in my driveway.

I think the tanks would be the best (for me) because you can put them anywhere, and they'll last for a long time.. I dont have a lot of floor space, but I do have some ceiling space.. (i got my carbon filter on the ceiling already)

anyone know what the ppm of co2 is if you just chill in the room for a while? my grow room air circulates from my office - where i spend all day - so i think my plants get all my co2 imp: just dont know how much it is - cuz i havent invested in a ppm meter.

I use a CO2 canister from a paintball gun. I partially screw the canister onto the gun to allow CO2 to leak out for 10-15 seconds every 3 hours during the light cycle. It's obviously not a precise method, but its cheap and the plants sure love it

If you have a larger grow room (im in a closet), a larger canister would be more logical.
