900W LED Grow Light!!

900w LED Grow Light 

Please Note

These are not your cheap fancy disco leds (these are specifaclly designed for plants DO NOT confuse these leds with cheap immitations ment for discos and public lighting that are scattered around the internet, just because they look the same please dont assume that they are , the cheap led lights some companies claim to be for growing plants will do nothing but cost you a lot of  time and money, be sure you buy the real deal.

Light is very important to plants as it is the source of their energy. Plants contain chlorophylls, that are the energy trapping molecules which use the blue(vegetative growth) and red(flowering) wavelenghs of the light spectrum. Green light is reflected which is why most plants appear green.

These days LED grow lights are nearly 98% efficient for chlorophyll production. They also emit very little heat and can produce savings of upto 90% in running costs compared to HP Sodium type lighting. Nearly 100% of the light an LED grow light emits is completely absorbed by the plant!

The truth about LED grow lights

When choosing a suitable LED grow light customers often find that there is a lot of conflicting information with regards to different wattages, colour spectrums, different sized LED’s and seemingly overly optimistic estimations of the equivalent output CFL / HPS / HID lighting solutions. The choice can be simplified a great deal with just a small amount of knowledge which is outlined below.

What type of lights do plants need to grow?

This question is really the most important issue to bear in mind when comparing different types of grow lights. Traditionally light bulbs have been measured in terms of Lumens. Lumens is a measurement of VISIBLE light to the human eye and the higher the Lumens rating on a light bulb the brighter the light will appear to the human eye. When thinking about the lighting needed to grow plants one needs to gain an understanding of what types of light plants respond to. Traditionally the solution has just been to use the most powerful HPS / HID lights which although effective only have a small percentage (15-30%) of their actual output in the correct spectrum for plant growth. One of the key advantages to LED lighting is that the wavelength of the LED can be specifically manufactured to coincide with the wavelengths that plants require to grow. This means as well as being more efficient at converting electricity to light in absolute terms LED’s used for growing can also be refined only to produce the spectrum of light which the plant will use to grow. This means that watt for watt LED can be 15 times more efficient than HPS / HID lighting at producing growing light for plants.  This means less heat, and less electricity costs.

Below is a chart of the plant growth plotted against light wavelengths. From this chart it is possible to see which wavelengths of light will produce growth in plants and then it allows us to make up a specification of LED light which outputs only the light at the wavelengths which are useful for plant growth for the maximum growth potential. Below is a break down of the different wavelengths of light and the effect each one has on plant growth.

The Peak growing wavelengths for plant growth occur at 425nm and 460nm and again at 640nm and 670nm. To get maximum plant growth it is ideal to target any lighting specifically around these frequencies. Any lighting out side of plant growth frequencies can actually be damaging to the plants as described in the data below. The wavelengths of light are on the bottom scale and the plant growth repsose is charted in the vertical axis (higher numbers on vertical axis = better growth as measured by chlorophyll production)
