In BC power currently costs about $0.083 per kilowatt hour (assuming growers will spend most of the year in Step 2). At this rate using a 120W LED grow light (which compares to a 400W HPS) during the vegetative stage (18 hours of daylight) you would save $153 a year on electricity.

(18 hours a day X $.083 per KWH X .28KW 280W difference X 365 days in a year).

Our LED lights produce only the wavelengths of light necessary for plant growth. This, combined with the fact that LEDs are very efficient, enables our lights to deliver the same plant yield as an HPS (high pressued sodium) lamp, while using a quarter of the electricity.

What wavelengths of light are necessary for plant growth? Plants obtain their energy from the sun by absorbing radiation (light) in a process called photosynthesis. The molecule that transfers the radiation into chemical energy, which the plant can then use, is called Chlorophyll. Chlorophyll only absorbs light at certain wavelengths. It cannot absorb green light, instead the plant reflects it. This is the reason plants appear green. The wavelengths of light essential to plant growth are shown in the image to the right. A higher absorbance corresponds to a higher efficiency when transferring energy from light to plant.

Will wavelengths of light that do not correspond to Chlorophyll peaks help plant growth?

No, the only wavelengths of light used in the photosynthesis process correspond to Chlorophyll absorption peaks. In fact, some wavelengths of light will hurt plant growth. Ultraviolet light in particular (produced by HPS lights) is responsible for damaging plants, just as it sunburns humans. In addition, infrared light (produced by HPS lights) only produces heat, if you have an thermographic camera you can see this type of radiation. Lastly, despite what some may say, carotenoids do not absorb energy in the orange spectrum as a quick check at Wikipedia will confirm.

Is it essential to produce wavelengths of light at the absorption peaks of both Chlorophyll A and B?

Yes, Chlorophyll A and B work in conjunction to produce energy for the plant. Only producing the light required for Chlorophyll A (while ignoring Chlorophyll B) would be the same as if you only ate food and never drank water.

Our LED lights use solid-state LED technology, making them last over six years, running at 24 hours a day. They are also guaranteed for three years with our three year no hassle warranty. If the light stops working for any reason ship it back to us, no receipt necessary, and we will ship a working one back upon receiving the broken one.

HID lamps produce intense heat and must be placed high above the plants to avoid scorching and drying them out. In addition to risking the health of your plants, these lights require additional equipment to control the heat produced and are one of the main causes of fires in an indoor garden.

In order to maximize growth the lights should be placed as close to the plants as possible, this is essential in sea of green hydroponics gardens. Since our LEDs are cool to the touch they can be placed right up to the plant, maximizing the amount of light the plant receives without risking burning.

Our LED lights produce enough blue light to allow plants to flourish in the vegetative stage, while still providing enough red light to enable plants to grow colossal flowers.

All HID lamps require ballasts and reflectors in order to operate. In comparison, each of our LED lights has an integrated power supply, removing the need for a separate ballast. Also, each high-power LED used in our lights is designed to focus its light directly onto the plants, removing the need for a reflector.

Unlike HPS grow lights, LED grow lights do not induce a huge start-up current. Your fuses and breakers will thank us.

The solid-state LED technology used in our lights enables them to start instantly, as opposed to the minute long startup seen in HID lamps.

HID and fluorescent lamps are very delicate and break easily if hit. Our LED lights are very durable; the LEDs are protected behind a Lexan window. This minimizes the chances of damaging our LED grow lights.

Due to our LED grow lights' tremendous efficiency they are ideal for solar or wind-powered installations.

In addition to saving energy due to their efficiency, our LED lights contain no heavy metals. Compact fluorescent lamps contain small amounts of mercury, which is released when the lamps are disposed of and contributes to air and water pollution. Save the earth, one organic hydroponics garden at a time.
