When a plant is indoors, light usually only comes from one source, like your sunny window, massively reducing the angles light is bouncing off from, and the amount of light and vital photons a plant needs. Measuring Plant Lighting There are a number of ways to measure indoor plant lighting levels. What you really should be measuring is the footprint of your plant canopy. Once we have a hard numerical measurement of the intensity of light in a space, we can start looking at what plants would do well.

For example, some plants require full sun to thrive, while others will grow equally well in full sun or part shade. Light. Also critical to this process are the proper design, layout, and mounting heights of the UV LED grow light to minimize plant shading and create consistent lighting levels. Return to Miscellaneous Agent Articles. When we bring a plant indoors, we literally invoke something called exponential reduction in photon exposure. It can be used to compare the performance of different illumination systems.

LED grow lights provide years of efficiency, high quality yield of plants, and save 50-60% on the energy bill. You can also find grow lights with a “best of both worlds” colour temperature of about 3,500K, which you can use for both vegging and flowering. As gardeners there is a lot to know when caring for our plants. Light intensity rapidly decreases as the distance from the light source increases. Light Requirements for Succulent Plants.

Sometimes these plants are classified as plants lying in the "occasional water zone". The best indoor grow light and the best nutrients will not affect yield as much as insuring that only flowers sites and select sun leaves see light, and that all flowers left on the plant get enough light. Plants need light to produce their own food through the process of photosynthesis. Plants "see" light differently than human beings do. As such, there remains considerable debate as to which method provides the gardener with the best information in determining if the light source is providing the ideal wavelengths and intensities to optimize plant response. Foot candles are an imprecise form of measurement, but they give us a good idea of how much light a plant is getting. Full sun. 4,000–5,000: About 50 percent of the midday sun, or strong direct sunlight in a bright room, good for plants with high light requirements; 5,000 and up: Very bright indoor light; When considering foot-candles, it's good to remember that full sun outdoors is about 10,000–12,000 foot-candles, so even the brightest of indoor rooms rarely approaches that level of sunlight. A grow light is an artificial light to help plants grow. But from the artificial light source, the distance is much less and therefore critical for how much light the plants receive. ), and not LED lights. The outside light was 8,000 fcs.
