Default 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.

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...

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.

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.
