I am hoping to build an indoor rockery in the large fireplace. I have been told I will need LED lights. I have white LED lights, but I have been told I will need red and blue but no one can tell me how many. Can you help with this information?
Indoor Garden Lights
LED plant grow lights have been engineered with the indoor gardener in mind. Each light uses an array of LED lights that offer the perfect spectrum of plant light. Two colors of LEDs, or "light emitting diodes", are used. The violet-blue light in the 400 - 520 nm range encourages chlorophyll absorption, photosynthesis and growth, while the red LEDs in the 610 - 720 nm range promotes flowering and budding.
Daily use depends on the type of plantings you have. Foliage plants need about 16 hours of light per day, while flowering plants require somewhat less, in the 12-14 hours range. For either type of plant, LED grow lights are very energy efficient compared with traditional indoor garden lights using fluorescent or incandescent grow bulbs, and they produce much less heat when compared with these types of lighting.
As with all high intensity indoor horticultural light, we advise using eyewear to protect against the bright light and UV rays. And if you need to show off your plantings, you may want to invest in a bright halogen light, as the LED grow lamps will give your plants an unnatural appearance when the LEDs are on.
The number and type of bulbs will be determined by the plant type and size of area used.
