c02 setup?

I want to set up a nice c02 system. What all will I need? I want to raise my ppms 1000-1500 in 4' x 12' area. The area is not 100% sealed. I will be hanging relflective material around flood tables.

buy a regulator and a co2 tank and tubing and your set.... only set off co2 while lights are on

Don't I need some sort of controller/timer to keep ppm levels in check? One tube above each table, or should I use some T fittings and a few tubes per table?

its best but you can figure out the math.. its a pain in the ass but worth knowing if you want to get into co2.
i just have my bottle hooked up to spray .5cfm(i think) 15min every hour while the lights are on...

If I have the money I think I am going to invest in a controller because I suck at math! lol I can't wait to use c02!

PPM monitors/controllers are usd$400-800
optimal co2 is 1500-2000ppm, with incresed co2 the plants can withstand higher temps

this is my first grow with co2... 3.5 weeks into flowering and the little buds are way ahead of what they usually are. first thing i noticed was the stems seemed plumper and just seemed really lush and green.

You know what plumper stems mean . . . . FATTER BUDS! 2000 ppms is pretty high. Did you use c02 in Veg stage as well? Have they been growing faster?

well the veg is attached to the flower chamber, its light sealed but not air tight.. and i noticed that my moms ont he floor of the veg room are doing better... these particular plants didnt get co2 untill there second day of flowering but they seemed to start throwing out hairs faster, its ak48, and half way will be this fri, i figure ill deff be able to see a difference by then... overall it looks about a week ahead of what it normally would...in the cannabis grow bible, it says perfect co2 can double or triple yeilds... i would be happy with 50% increase... so far i dont think thats far off.

my setup is in a closet with my co2 tank hooked up to a soda keg full of water to bubble. not air tight at all. how long should i run it a day to get good levels?

ibought a nice set up and looked at my veg room witht he meter and my ppms where 2000 lol my living room was 1200 i tested my friends place and it was the same . Seems like inddor co2 levels can get pretty high with just us breathing inisde them. Before you go out and buy all sorts of shit buy the meter to test your room and c if you need it or not.

Here's a link to a great calc that will take the math out of your lazy brain.

Best to attempt to make the room airtight and avoid the leakage so the CO2 doesn't get wasted. I turn off the exhaust out take while running the emitter.

Good Luck Amigo.

So you guys wouldnt reccomend the liquid propane burners? I too am looking to add co2 to a 4x8 flowering room...

That was a sweet ass link! Thanks for the help.
