Below 200 PPM, plants do not have enough CO2 to carry on
the photosynthesis process and essentially stop growing.
Because 300 PPM is the atmospheric CO content, this amount
is chosen as the 100% growth point.
Above 2,000 PPM, CO2 starts to become toxic to plants
and above 4,000 PPM it becomes toxic to people.
With the advent of ideal growing conditions conditions
provided by high-intensity discharge (H.I.D.) lighting systems
hydroponics, controls such as temp., humidity, etc. and
complete, balanced plant nutrients such as Holland Secret,
the limiting factor on plant growth rate, quality, size
and time to maturity becomes the amount of carbon dioxide
available to the plants.
Not only can you garden less expensively, but
you can garden renewably.
