With the proper supplies, the McMurdo greenhouse functions like any other greenhouse. The main difference is that our greenhouse is completely sealed in and insulated, while most greenhouses in the states are made of glass. There are electric heaters and a furnace to heat the rooms at night, and daytime temperatures are maintained through the combination of heat from the HPS and MH lamps and various intake, outtake, and circulating fans. All of the systems are of the recyclable kind, with each type of plant growing in its own system.
For example, there is a tomato system, a pepper system, three herb systems, two stacked green/lettuce systems, and three cucumber systems (see pictures to the right). Each system contains its own reservoir, pump, aerator, water heater, and PVC troughs and tubing. We utilize a three-part liquid nutrient and pH adjusters, which are administered by hand after a daily meter reading. One full-time greenhouse technician takes care of everything!
