co2

[Growdude]

If one wanted to charge a room with co2, couldnt you just buy a small tank of it at a place like Airgas co. and release some into the room every day?

Sure you can do that, but is it going to do any good? Thats the question.
And I can tell you from experiance its not going too.

I'm sticking with CO2 can never hurt but only help. If just "talking" to your plants helps then I'm sure a CO2 canister will help also. To know the difference with CO2 enrichment and without, you would obviously have to experiment. So unless you can REALLY tell from experience then no1 has a right to say it DOESNT help when it actually does. Thats the same as debating people breathing better out in the woods than they do in NYC. So when you say you have "experience"... I want pics!

well since u dont wanna take anyone else experiance, go talk to someone in an agriculture shop, he'll tell u the same thing.

 

[Celebrity Bob]

He'll tell me that CO2 wont help my plants? I'd love to hear that! I talked to the guy at our local garden supply and he said EVERYTHING helps.

So when you say you have "experience"... I want pics!

Here are 2 harvest pics.
Pic 1, I spent over $100.00 on co2, used 20 lbs tanks.
Pic2, no co2 was used at all.

Im not trying to suggest that No added co2 is better than proper co2 enrichment. But this will give you an idea what can be done without it.

 

[Celebrity Bob]

Were they same plants with the same growing conditions?

Were they same plants with the same growing conditions?

Everthing was the same, nutes, lights, all done hydro, strain, grow space.

Really this is just to show you what can be done with no co2, just fresh air.

 

[Celebrity Bob]

So you got a bigger harvest without co2? I jst dont see how it can't help. Like I said I do it because it makes me happy.

"IF" he is honest, he'll tell you that emitting paintball canisters in a vented room is a waste of money. "EVERYTHING" helps??? He wouldn't be trying to sell you "EVERYTHING" would he?:hubba:
The information is easily accessed via the www. I refuse to do the work for you. But if you will investigate, rather than argue, you will find that most everything you've been advised, is absolutely correct.
C02 enrichment requires certain environmental factors in order to be effective/efficient. If you are not providing those requirements, you're not being effective.

I just don't understand how you guys can say with such certainty that properly implementing co2 during your light cycle will not produce amazing results,

I don't think "anyone" has said that.
"properly implementing" ... are "key" words there.

well...

IMO there is no need to add aditional CO2 if you have fresh air supply

it definatly cost more than you'd see in results to charge a room

GrowDude, excactly what is your experience with CO2? Spending $100 on what and what were the conditions in your room.

Everybody seems to be forgetting a very important fact here, you either have GOOD ventilation OR CO2, NOT both. Why would you spend money injecting a gas into your grow room that your exhaust fan will remove in about 20 seconds?

Now Cost v Benefit.

What you need to construct a properly implemented co2 enclosure:
Brand New Aluminum 20LB CO2 tank = $150
Green Air DH-CT-3P or equivalent = $250
HydroFarm COSYS = $150
QUALITY Timer (15 min cycles) = $100

Total = $600

Now just to err on the side on conservatism we'll say that you can buy 3 ounces for $600. So any increase of yield of 3 ounces will instantly be a benefit to the invested costs. Now since in previous grows I have seen approx 1-1.3lbs a 30-40% (value of $900-$1600 based on the $200/ounce) increase in yield would recover my investment in a 3 month period.

 

[DankCloset]

yes but you'll never see results like that from cfl's, or even the shop lights there using, most grow rooms are thrown together. key words there, "construct a properly".... check out his grow room.

not meaning to be an *** or anything, but for the sake of a decent argument

 

[Growdude]

Bono, The $100.00 was just the cost of the gas, I have a 20 lbs tank, CFM flow regulator, timer assy and delivery tubing.

My grow is in a bed room closet with the doors wide open each day, I would discharge enough gas to reach a min of 1000 PPM in the entire bedroom.

Only if I open the window do I get true fresh air.

But this has allways been my growing conditions and it was the same for both grows.

The point is if you can grow buds bigger than 2-liter bottles without co2 you dont NEED it.

 

[DankCloset]

amen, my very first grow i just about killed my plants being a fanatic

I don't think anyone has forgotten. The subject was/is based on paintball canisters, flourescent lighting, and ventilated grow area.
"Fresh air" doesn't necessarily constitute "outdoor" air. "Fresh air" as in "non"stagnant/c02 depleted air from anyplace, including an adjacent room. Possibly inhabitated by humans, which produce c02 as a waste product.
C02, properly administered, under proper conditions, has been proven to be beneficial. Speeding growth, improving yields, ect.
C02 emitted from yeast/sugar concoctions, paintball canisters, ect. have not.
Proper circulation/ventilation IS more beneficial than these methods.
