Lighting for Indoor Bonsai and House Plants - Bonsai Trees for Beginners Series

Suitable amounts of light is critical for the survival and health of a plant. Low levels of light make a plant weak and susceptible to all kinds of pests and disease. Giving your plant the right 'strength' and 'colour' of light could make the difference between a vibrant or struggling bonsai...

The first thing we have to do is identify the quantity of light that youre looking at in the area that youre going to put your bonsai. You use a little light meter for that. The light meter generally has a lux which tells you the density or intensity of light. On a good bright day, you could have around 100,000 lux outside in the bright parts of the world. In the tropical parts, maybe 6000K and on a cloudy day, it can go down to 4000 lux. On dark days, it can get even less. Indoors, the light levels vary quite significantly. The human eye can read at 198 lux, but even the plants that live in the undergrowth in the Amazon forest require at least 400 lux to survive. Ficus and other indoor plants can generally manage at that kind of light level. Bonsais, on the other hand, generally need a lot more light. 3500 4000 lux is a good reading to have. You need to then choose appropriate lighting for the area that youre going to have. Sometimes you can have light that creates heat. HID High Intensity Discharge lighting. Then there is metal halide lighting (MH) and theres also HPS or High Pressure lighting. They use a lot of electricity for one but they also generate a lot of heat, and the other thing about this kind of light is that its a general spectrum, so it goes across the entire spectrum of light. Most of the light, or 20% of the light is used by the plant. Using fluorescent light, which is the other type of light is more accurate and fluorescent lights are colour corrected. You can get very precise lighting for the plant depending on what your plant is doing, whether you want it to grow leaves and be used between 500K and 6000K. It is a blue light and then you have for flowering, you would use 2000 to 2700K which is on the red spectrum. There is a new mention in the plant light area, made from LEDS - light emitting diodes. They generally come in panels or in strips. They can be used right over the plant and sometimes, if its a long strip, can even put it within the plant to light up the area. Its not advisable to run the light 24 hours a day because trees need to rest. Trees need to be dormant in the night. When you can feel the heat and light outside, thats the best time to have your additional lighting or support lighting for the trees.
