CD-3 through CD-36

Carbon dioxide enrichment equipment and methods have improved as
experience and the understanding of atmospheric control and plant physiology has
advanced. Plant metabolism and growth rate are dependent on the
available atmospheric CO2. Plants are keenly sensitive to CO2 variations and
optimum values must be constant and precisely controlled. The method, timing,
and size of equipment must be properly determined to provide maximum
benefits and economy. Carefully follow the operation charts to choose the proper
size generator for the cubic foot area. Keep the recharge times to a minimum
for best results.
Do not undersize the generator or optimum results may never be achieved.
