Grape Swirl Orchid Grown Grow

Two 1000W HPS lamps provide supplemental lighting for the hundreds of exotic orchids in this custom greenhouse. The lamps have integrated timers which turn on as the greenhouse falls into the shade cast by a nearby tree line. About a year after taking this photo, the author paid another visit and found two more lamps installed and nearly double the number of plants. I guess gardening kind of grows on you!

In nature, plants depend on the energy of the sun. Through a process called photosynthesis, sunlight is converted into sugars to provide fuel for the plant's growth. These sugars are utilized as needed in a process called respiration, and excess sugar is also stored for later use. Photosynthesis is made possible by chlorophyll, which is contained within the leaf cells. Chlorophyll gives vegetation its characteristic green color. Light is trapped by the chlorophyll, activating the process of photosynthesis. Inside the chlorophyll, light energy is combined with carbon dioxide and water to produce oxygen and sugar. The sugar is then oxidized (or metabolized) through the process of respiration, producing carbon dioxide, water, and energy for growth. Excess oxygen and water are transpired by the leaf into the air. Plant growth, therefore, is directly affected by the color, intensity and duration of the light the organism receives.
