Super Bright LEDs - LED Information. Solid State Lighting Design - LED Lighting for General Illumination and Architecture. Aquaponics. Aquaponics is a combination of aquaculture (raising fish) and hydroponics (growing plants without soil). The wastes from the fish are broken down by bacteria living in the growing medium, and converted into a form that can be used by the plants. Integrated Vertical Tube System Here's a drawing and a photo of the integrated vertical tube aquaponics system we built. The photo shows the tubes in the planting/harvesting position; normally they are rotated 180 degrees so that the openings face the window.
I made the drawing using Google SketchUp, a great free 3-D drawing program. To make the grow tubes, I cut slots across with a hack saw and then heated the plastic with a heat gun to soften it. The PVC caps on the bottom of the tubes have slots cut around the edges with a table saw, so that any water that might drip out around the plants can just run down the outside of the tube and through the slots.

There are UV lamps for tanning, for counterfeit money detection, blacklight stage lamps and lamps for mineral displays, lamps that produce Ozone and germicidal UV lamps. The focus of this text are the germicidal UV lamps, which emit shortwave UV light in the ultraviolet section of the spectrum known as UVC or germicidal UV. There is more information on UV in the UV Facts section. Here we will discuss the artificial UV production by UV lamps and the specs of the different types of UV lamps. People also refer to the UV lamps as UV bulbs as in regular light bulb. UV Lamps – History and Development UV light is artificially produced by mercury vapor low and medium pressure lamps. All germicidal UV lamps have secondary emissions, including small amounts of UVA, UVB, visible light (above 400nm wavelength) and heat.
