The image below shows the typical wavelengths of everyday lights that you would be familiar with.
In comparison, this image shows the ideal wavelenths required for plants growth. As you can see plants primarily require blue and red light between the 400-500 and 600-700nm wavelengths. Other portions of the light spectra are not always utilised by the plants! Which is why if you got a regular light globe used in your kitchen, it COULD grow a plant, but most likely wouldn't, as most of the light is wasted by emitting light at the wrong wavelength. Keep in mind that every plant has a slightly different requirement for light intensity, light spectrum, and the amount of exposure required.
We have two main types of light that we offer, the full spectrum options and the red/blue options. The full spectrum options typically have cool white light (which is primarily blue wavelength) with a few red diodes in there to provide the upper end of the spectrum in the 600-700nm range. The red/blue options provide only light within the 400-500 and 600-700nm wavelength range. Red/blue lights are meant to be more efficient, but we have been finding that the white ones perform similarly well, often the choice comes down to personal preference, we understand that most people don't want a purple light in their home, so for most people a white light will do well enough.
The image below shows the spectrum of products such as the EcoKitchen. As you can see the red lights which are dotted throughout the light panel, supplement the white light which has blue light in it.
And this image shows the spectrum of purple light products such as the BreezyGro
Overall, there is a big difference between household lights and growlights, in particular LED grow lights which are able to provide very specific wavelengths of light to plants. LED grow lights have the highest PAR (photosynthetic active radiation) levels of any type of grow lights. Our products have been tried and tested by tens of thousands of customers and our reviews speak for themselves!
