Co2 question

Growgirl · Nov 14, 2007

Hey I am thinking of adding my 400watt hps to my veggin babies (2weeks old 4,5nodes), I alrdy have them under a 400 MH so I figure the temps ould rise b.c of the two hid's combined. So I was thinking of adding Co2 to help with any temp issue, I read a nice cheap way in the DIY section in the GrowFAQ https://www.rollitup.org/view.php?pg=faq&cmd=article&id=262 (this one) I wanted to ask if anyone here had tried this method, or if there was any known problems?? If it works with no draw backs, this would be real convenient, so please reply and let me know something :mrgreen:

Thanks, GLG

Alot of people use this method but to me in actuality if you do the research this method would only add a minimal effect if any to the foiliage not the buds and it would need to be a very small enclosed grow are less then 3 feet by 3 feet by 4 feet. To benefit from actual co2 usgae in the way co2 benefitsd are described you need a ppm of co2 aroun 1300-1500 for max results.This has to be maintained daily while lights are on and then the vent system has to be set to exhaust and intake on an alternate scheduled to not interferr in fresh co2 build up then replecement.You can buy a co2 boost bucket for around a $120 which will help in a smaller area but for any area where you gonnas have more then 1-2 plants the little co2 2 liter is kind of just to make people feel good about doing stuff.Even a propane burner in a room would help a great deal but adds heat

I've just got myself a 20lb tank and a regulator, still trying to figure out how i'm going to go about setting this fucker up.

I need more bits i think.

you need a 20 lbs tank, a solenoid, a timer, some hose and if no regulator on your solenoid a regulator to adjust the flow.Then you just have to off time and damper your intake and exhaust fans. I run my tanks about 2-3 minutes every other hour during 12 hour lights on. I have damper that close my exhaust and intake fan vents while co2 is present. I then have the intake and exhaust fans kick on for 5 miutes right before every 3rd hour. This refreshes the old air with no then the damper close and a new co2 injection comes on just as the fans had went off refilling with fresh co2. Then since co2 is heavier then air your houses are above the plants falling over them I hav e a tilt cyclone fan on the floor on low sending the heavy co2 back up and over the plants.

I've got the 20lb tank, plus one of these regulators/solenoid

i'm ordering a co2 flow meter like this

and then some dispersion tubing to go around the ceiling.

Is there anything else i need?

Nope that flow meter your getting is the right kind. Then just a good digital timer that does increments of 1 minute on a monthly scheduele so you can set it and for get it.Then just watch your tank level and when its empty refill time
