All green plants require light to perform photosythesis, during which special cells convert the energy contained in the light into sugars. In the process, plants give off oxygen.
Plants vary widely in how much light they need to thrive — from low-light houseplants, such as dracaenas, to fruiting edibles, such as tomatoes, that need much brighter light.
Seedlings require lots of bright light, and when they don't receive enough they get weak and leggy. In most cases, even the sunniest windowsill won't provide the intensity or duration of light they need, especially in winter.
Intensity describes the amount of light that reaches a surface at given distance from the light source. A super-bright bulb that's 12" from a surface might, for example, provide the same light intensity as a dimmer bulb that's 2" from the surface.
Duration describes the number of hours of light a plant receives in a 24-hour period. We can control it by turning lights on and off or, more easily, with a programmable timer.
Color describes the visual appearence of light. Most grow lights provide full-spectrum light. Most of the light plants use is from the blue ("cool") and red ("warm") ends of the spectrum; they use little yellow and green light. Blue light stimulates vegetative growth (foliage and roots) while red light stimulates plants to produce flowers and fruit.
Our LEDs and fluorescent bulbs both produce full-spectrum light. However, LEDs are better for plants, the environment, and your wallet.
Regular incandescent bulbs are not used for indoor growing because they give off too much heat and can burn tender foliage.
Our SunLite Gardens and Stack-n-Grow lights are available with LED or fluorescent lights. Our Bamboo Grow Light Gardens feature high-output LEDs. This chart can help you choose the best lights for the plants you're growing.
