CPS: Continuous Production Systems Part IV Water cooled lighting allows for the closest plant to lamp tolerances possible. Sure, some of the light gets lost through the water, but the grower can provide incredibly high light levels to the plants, as the water cooled units run cool enough to allow the placement of 1000 watt HID lamps within inches of the plants, if required. They also help to create a very quiet growing environment. Air-cooling can be quite noisy, even with some of the grow room construction secrets revealed through this series of articles. In this model, the following areas can be adopted to water cooling for high efficiency, optimal grow room temperatures and crop performance: • CO2 burner • Water cooled lights • Hydroponic reservoirs • Air Conditioners • Air cooled lighting with in line heat exchanger (converted to a modified “open” system) Microbial Inoculation - The beneficial microbes in the prepared cartridge have been triggered to break dormancy. In the next 24 hours, their populations may multiply billions of times before being applied to crops. 44 MAXIMUM YIELD USA - March 2009 All of these items, excluding the water cooled AC, can be connected to the same water tank a nd cooling system, although a very large volume of reserved water would be recommended if connecting a water cooled CO2 burner to the same water cooling system as the lights. Above ground swimming pools are inexpensive, or existing swimming pools or other bodies of water can be used. One of the great things about the water cooled lighting system featured in this article is that it is suitable for vertical installation. In the earlier phases, when plants are smaller and branching should be encouraged, containerized plants can be huddled around the vertically mounted unit. With the extremely close plant to lamp tolerances, and the fact that the light is being delivered to the sides of the plant (which should be rotated daily or at least every few days), early flowering growth is squat and
