awesome site. I have the regulator show there. but I lost the chart that came with the regulator when I moved and was going on rough estimates. maybe I should have checked the site a while ago......thanks for the post it's much appriciated

i"m a rookie in this game and about to start my second operation. My first grow went really well got about an ounce per plant with no co2. A friend said if i'm doing soil it's a must. The tanks are exspensive and would really set me back so do i really need to put co2 in my room? What would the benifits be?

anybody ever use this product :CO2 Boost - Supplier of CO2 producing mixture for the purpose of CO2 enrichment and air fertilzation ?..im looking to do my very 1st grow w/ bubbleponics..i know,i know,alot of work for beginner,but very good at learning as i go and willing to dedicate my life to gettin it right...and besides i love this site for expert help,have seen great grow journals..now my question is...do you need to use co2 when growing with hydro??

I added CO2 a couple of months ago and my harvest has increased from 12oz. every three weeks to over 16oz.
The buds are super dense and the steams are thicker.
It's obvious that CO2 was a limiting factor in my flower room. I'm running two 1000W HPS and three (14 site) Aero/NFT systems in a 7X8' closet.
I run the CO2 every two hours for 15 minutes. I adjusted the flow according to the formula in this sticky.
I also measured the CO2 in my room with a CO2 testing Syringe. It took about 10 syringes to dial it in. It's still never right on though.
The calculator in the sticky link really works. But all it does is tell you how much gas it takes to fill your room. It doesn't take into account how much the plants use or any air leaks.
It's not a big deal you just have to use a testing syringe every couple of hours to figure it out. Those little bastards are expensive though!
After a couple of months I've realized that a CO2 sensor/controller is a must. CO2 may be a waste if you don't have lots of light and other limiting factors but if everything is dialed in, watch out! You will see amazing results that more than pay for the costs.
The good news is I found a great deal on fleabay a couple of days ago! A complete greenhouse controller with CO2 monitor/regulator. It will take care of all my fans, lights, humidity, temp and CO2 all in one box. I'm stoked!

The controller monitors the CO2 levels in your room. When it falls below 1500 PPM the CO2 switches on the CO2 regualtor/solenoid and lets the gas out.
When the room gets to the right CO2 level the controller switches off.
I also automatically switches off the CO2 when the fans are running to reduce waste.
The CO2 is actually distributed through a hose (with holes in it) running around the perimeter of the room.

That's pretty nifty. Not sure what CO2 does, I guess it gelps the grow though. Lots of growers use it. I can't afford something like that right now. This little system is $155.00.

Carbon Dioxide Generators & Regulators
> Carbon Dioxide Regulators
> Hydrofarm CO2 (.2-2 cubic feet per hour) with Timer
A CO2 system releases gas from a carbon dioxide bottle (not included). Plants use CO2 during photosynthesis. Increasing the carbon dioxide level to 1500 parts per million has shown to increase plant growth up to 30%. The output is adjustable from 0 to 2 cubic feet per hour with the flowmeter. It also includes a solenoid that opens and releases the gas when power is applied. Our CO2 calculator will help determine what level to set the flowmeter. Timer included.
CO2 is an odorless, invisible, and non-flammable gas. It is also safe for humans in the maximum concentrations recommended for plant growth. The average level of CO2 in the atmosphere is about 300 PPM (parts per million). If the level decreases down below 200 PPM in an enclosed growing area, plant growth slows to a halt. Through the years of testing and research, the optimum enrichment level of CO2 for plant growth has been agreed to be about 1500 PPM. With CO2 enrichment, under good conditions, plant growth rates and flowering will increase 20-100%. CO2 can be used from seedling right through harvest.
Deliver growth-boosting CO2 with our user friendly, easy to operate system. With its programmable timer, it will automatically maintain ideal CO2 levels for optimum growth. For small to medium size areas select the COSYS, for larger than 10' x 10' areas, select the COSYS20

I go through 3 - 20gal. tanks a month in a 7x8 closet.

3 - 20 gal tanks?!
I found 10 gal tanks for $120 ea 10 lb. CO2 Cylinder, CO2 Tank/Cylinder > CO2 > Saltwater Aquarium Supplies
How much are 20 gal tanks and how much are they to refill? Are you using a regulator on a timer, or are you just letting it leak?

Are all CO2 bottle created equally? I found that bottles for beverage machines are cheaper.
Beer CO2 & Nitrogen Gas Cylinders (Air Tanks) - MicroMatic
They have a 20gal for $109

I use a CO2 controller. It monitors the CO2 and keeps it at 1500 PPM. It also controls the heat and humidity. So when my exhaust fan kicks on the CO2 shuts off.
It costs me $17 dollars to fill the tank. CO2 added 4 oz. to my harvest. Now my flower room produces a pound every three weeks.

Wow, this will definitely come in handy for me one day. Good post.

So, using 6 bottles (8 week cycle) @ $17 ea cost you $102. And it added 4oz to the harvest?
How many plants were you harvesting? If you added 4oz to a 1lb harvest, that would be pretty good. If you added 4oz to a 10lb harvest . . . that's not as dramatic. You said 7x8 so you could be harvesting 50+ trees. That sounds like an 8lb harvest so an extra 4oz may not be worth the hassle. The money equation certainly works out well, but not that great percentage wise (assuming you had a monster harvest anyway).

Adding CO2 added 4oz to my normal 12oz. harvest. So right now I harvest a pound every three weeks.
I run a 3 week perpetual harvest. Want to read how to do it?
