Here is some stuff that I answered yesterday on KP's thread and I am pasting it hear so I don't have to re write it.
"OK Lady and Gent. Co2 CJ, well the right way, not the ghetto way that I am subject to at this point is to run your CO2 with a controller that measures the
CO2 of your room and turns it off at the appointed level. With the levels there are two schools of thought, one school says to run the CO2 at 1500 PPM
adding your household PPM which is approx 300 in most house holds so that means that your controller would be set at 1200 PPM and run this in approx 3
hour intervals while exhausting the CO2 out of the room before the next treatment of CO2. The other school that seems to make more since to me is to run the PPM of your CO2 at the same PPM of your nutes and this is the reason
why, the CO2 kicks your plants into optimal production and being such it demands more manufacturing of needed nutes and other growth related synthesis
to flourish under the CO2 treatment and as you match the PPM's you are meeting the demand of the PPM level of the CO2 with the PPM of your nutes to keep
the demand and production in balance. Some studies show that having a greater CO2 puts a bigger demand on the plant that it can't handle as well with proper nutes, it is kind of like taking royds but eating like a 130 LB person who lifts 110 LBS, while you are now 200Lbs and pushing 315. The muscles would be damaged or not develop as well because they couldn't keep up with the demand on the energy and protein requirements. SO those are
the two main schools of thought. Some controllers have light sensors that will shut off any CO2 dispersment off once the lights are out because plants
only take in CO2 during photo synthesis and releases it during dark cycle while taking in O2. Also temps should be at least 85D for the CO2 to really be
able to be absorbed and broken down by the plant, and they say that 95D is optimal. There is a argument about the light/photo synthesis needed from a lumen
output for the plants to be able to process the CO2 and one thing I know for sure at this point is that anything under a 400w will not create the kind
of photo synthesis in the plant that will allow for an efficient break down and an absorbssion of the CO2 and some will even argue that it is only 600w
and greater that can really create the needed lumens for this process."
Also, some do use CO2 when in veg but not as many as do for flower only IMO. It is true that CO2 can help the plant when in the veg stage, but with the plant being smaller in the veg stage and when in flower working harder and performing a greater amount of photo synthesis with greater vigor and growth while in the stretch and bud production, proportionally your plant is able to take in and use a much more efficient amount of CO2 than say some little 7 IN plant in veg that is still really just working on a root system. The root system has more to do with the PH, nutes, O2, temps, pot size or hydro medium and once that monster root system is established then the CO2 can come in and make that system work by giving the upper floor of leaves, stems, branches and bud sights
an athletic diet of CO2 that makes the plant process the light synthesis like it is on royds and when the lights are out the plant releases all that CO2 and takes in all of that O2 and starts the ground work in the soil to rebuild and restore and fortify for tomorrows work out. It is kind of like working out. When your working out, carbs help to provide the catalyst in the form of stored glycogen to help provide needed energy to produce the strength for the workout and this is kind of like the CO2. The protein helps to rebuild the muscle after the work out and rebuild it back up during protein synthesis and this is like the O2 and the nutes in the soil.
Well hope this helps some.
PS, I think that Trainable's long a// log gives one of the best discriptions of real time use of CO2 on the board so if you get board then read his thread, he even states some of the equipment that he uses, I have read up on the equipment on the sights that he so kindly took the time to attach just to be a little more informed of the products out there and there different uses and it was a good lesson.
If a Bear smokes a fatty in the woods while no one is there does it still smell?

BlueBear Reviewed by BlueBear on . All Questions Concerning CO2~ So i am setting up Tanked co2 in my grow area this weekend and need some advice. i have been getting completely different answers from different people about the methods of co2 usage. as many people have questions about co2 on this forum, i thought one thread for co2 questions would be usefull as it would give more info in one place. So if you have any questions about co2 or you can help some one with co2 questions, please ask or do so here. it will make it easier for every one! I found some Rating: 5
