Light intensity is a measure of light energy hitting the plant surface and is also very important to plant health. For traditional interior lighting applications, light intensity is discussed in terms of foot-candles of light energy. While foot-candles is not the preferred measure of light intensity by horticultural scientists (who prefer a measurement in terms of “photo active radiation”), we have found that foot-candles will suffice with a proven light source, such as LiveWall’s Norb® Botanic. And, for most tropical foliage plantings 200-400 foot-candles of light energy hitting the foliage, is sufficient.
LiveWall, LLC has developed a plant selection and pairing guide for indoor plants based upon their lighting and water needs, and growth habit. This LiveWall design guide should be consulted for the correct light intensity for the type of plants that one intends to use. We have categorized the plants into lighting needs as follows:
