We measure light quantity (or intensity) in foot-candle or lux (metric). You can increase the light by surrounding plants with reflective materials, a white background, or additional artificial lighting, or reduce it by using woven or cheesecloth shade cloths to cover plants. Light is an essential factor contributing to a plant’s productivity. We refer to the intensity or concentration of sunshine as light quantity, a factor influenced by the earth’s rotation around the sun and your distance from the equator. Understanding a plant’s light needs (photoperiodism, phototropism, and photosynthesis) helps us know what they need when they need it.

We must understand how these elements influence the formation and growth of plants. Other times, ecological stress weakens a plant, making it more prone to diseases and pest attacks.Īt the risk of repeating myself, indoor plant health depends on the gardener’s ability to replicate the specific plant’s natural habitat light, soil, temperature, water, humidity, and nutrient availability. In some circumstances, a plant is directly harmed by unfavorable environmental conditions, such as inadequate light levels. Most plant issues are brought on by environmental stress, either directly or indirectly. Light Factors that Affect Plant Health and Productivity These Low-light plants effectively harvest and convert light to energy using a protein called light-harvesting complex, or LHC. Trailing plants still have maximum light exposure without needing the energy to remain erect and make ideal hanging-basket plants for low-light areas.

The photosynthesis process depends on light energy, and different plants need different light intensity, quality, and duration levels. We get paid a small commission from your purchases. This article may contain affiliate links.
