Introduction to co2....
chlorophyll pigments absorb light and convert it to electro-chemical energy.
This energy used to cleave water and combine the H with co2 to form sugar and release oxygen.
Plants gather energy from light using chlorophyll located underneath the leaves. stoma small pore like openings found mostly on the underside of the leaves intake co2 and release oxygen, all at the same time. Furthermore the roots absorb water and newts from the planting medium. the stored energy is use to split water molecules h2o. the oxygen o2 is released as gas. the hydrogen atoms combine with water to make starch, which is converted into sugars,
the entire process is called photosynthesis.
then the sugar is used to fuel metabolisim as a building block for amino acids which are turned into proteins that are used for growth. (just like humans)
6(h2o)+6(co2)+light=> 6c12h60+60 = .001
What that means is 1 pound of c02 consumes 8.7 cubic feet
You can calculate how much co2 is needed to bring a growing aera to 1000ppm (which is optimal) by
multiplying the cubic area of the growing room (length x width x height) by .001.
The total goal number represents the the number of square feet of gas requires to reach an optimal
level of co2 available in your grow room environment.
For instance my old grow room:
13x18x12 contains 2808 cubic feet
so 2808 x .001=2.8 cubic feet of co2 required to grow
optimally with all environmental issues in place and dialed in.
so in short a room 3x3x4 requires .36 co2
Effect on temperature on photosynthesis. As the amount of light increasing past 56,000 lumens per sq foot one foot from dry 1k light the plants can utilize the extra energy fully only when the concentration of co2 in the air increases. However, as light and co2 concentrations increase the plants metabolic rate is regulated by temperature.
In this light and co2 levels are constant and should be maintained. (closed grow-room easy flow through more complicated)
Photosynthesis and the metabolisim of the plant increase with the temperature.
As the temp rises from 50deg to 90deg (40deg bounce) at the leaf surface photosynthesis increases by a factor of 5
from 70-90 deg (20deg bounce) it increases even more 2.5 with all environmental elements in place.
With a total of 7.5 rate increase. NOTE temp is measured at surface, not ambient air temp....
Co2 TEMPERATURE AND LIGHT--- co2 usage and photosynthesis are effected by temperature. Plants received three uniform temperature regimes
50-70 had more co2 than they could use and newts room ran at 600ppm
70-85 also had more co2 than they could use at 1000ppm
80-90 used nearly twice the co2 and made huge harvest. almost 50%..... (strain DE-pendant)
Plants grow heavier and faster when supplemented with co2. raising the level of co2 up to 0.15% 1500ppm or a little more than 4 times the amount of co2 in the outdoors, thus increasing plant growth indoors using co2 either by fresh air or co2 introduction.
Here are some basics,
when plants in an enclosed area, their is a limited amount of co2 for them to use. under bright lights 1,000k plus, co2 is used up very quickly.....
Enclosed gardens with little or no ventilation are at the worst with co2 and environmental elements depleting and generally not replenished to the point where the photosynthesis slows to a virtual STOP. (around 200ppm). Only when co2 is added to the environmental can the plant resume photosynthesis.
A small closet or room can be recharged with co2 by opening a door or introducing a air flow via fan from outside. This incresses the co2 value in the room passively not positively (my grow room)
The slowest rate of photosynthesis is 200ppm under low light conditions 10,000 lumens, the photosynthesis rate increases at around 400ppm while increasing co2 concentration beyond that, without increasing light intensity does nothing it does not increase the photosynthesis rate any higher.
THE PLANT CANNOT TAKE HIGHER LEVELS OF CO2 WITHOUT LIGHT MASS AND INTENSITY....
At a light increase of 300,000 lumens the photosynthesis rates increase more as the co2 concentrations increase to 600ppm, above 600ppm of co2 the rate of photosynthesis climbs, but even at a slower rate as before until co2 concentrations reach 1000ppm.
By increasing your co2 and all environmental elements you can make your plant absorb more co2 and newts thus increasing growth and yield.
when plants receive around 60,000 lumens per square foot they can utilize 1200-1500ppm of co2.
Very few gardens are equipped with such powerful indoor lighting or the technology to supply plants with co2 but their are many ways to do this,
you can supply your garden easily and cheaply just but providing fresh air to your garden......
Hope it helps......

Ignorance of all things is an evil neither terrible nor excessive, nor yet the greatest of all; but great cleverness and much learning, if they be accompanied by a bad training, are a much greater misfortune. Education is a progressive discovery of our own ignorance.
