Hi Doug ; Please check the number 10% CO2 with a reliable source, I think it is off by a factor of 100, and I cannot find any references on the net that come anywhere close to it. Normal air contains about 300ppm (0.03%) CO2. General consensus is optimum levels for many plants is 2x-3x higher (600ppm - 1000ppm or 0.06% to 0.10%). If you increase temperature and provide sufficient light and nutrients, large improvements in growth are possible. Plants which are classified as C4 photosynthesis (corn for example) do not respond as well.
