The relationship between light and CO2 levels is important. The diagram explains it conceptually. At low light and low CO2 there is not much energy to play around with for up or down-regulation of the pools of Chlorophyll or enzymes contained in the plant. If we then add a little more CO2 to the system the plant can afford to invest less energy and resources in CO2 uptake and that leaves more energy for optimizing the light utilization - Chlorophyll can be produced without fatal consequences for the energy. Hence, although we have not raised the light, the plant can now utilize the available light more efficiently. Exactly the same explanation can be used to explain why increased light can stimulate growth even at very low CO2 concentrations. With more light available, less investment in the light utilization system is necessary and the free energy can be invested into a more efficient CO2 uptake system so that the CO2, which is present in the air and water, can be more efficiently extracted.
Providing macro and micronutrients to plants is easily done with commercially available fertilizers. It is often a more difficult and expensive task to provide adequate light over the plant. Both numerous fluorescent light and halide lamps will produce sufficient light if supplied with effective reflectors, but it could become very difficult to offer enough light to small light demanding plants on the edges. Based on known experiments, I suggest commencing CO2 addition before any other action is taken! I believe that even at very modest light intensities you will experience a conspicuous change in plant performance. The exact amount CO2 may always be discussed but concentrations from 10-15ppm will only improve plant growth. You will probably see that plants, which were barely able to survive before now thrive in the presence of CO2. These conclusions were derived from work conducted by Ole Pedersen, Claus Christensen, and Troels Andersen.
