The lack of sun in many environments made its use popular Artificial light for indoor plants. Choose A LED fitting and understanding of PPFD It allows you to give them the energy they need without the risk of burns.
the Advances in LED lighting It allowed the development of lamps with a spectrum suitable for plant growth. Unlike older systems, it offers lower consumption and more stable emission. The resolution of the spectrum and intensity of light determine how a plant responds in its development cycles.
in Environments where natural light is insufficientArtificial devices help regulate photosynthesis and maintain basal metabolism. The power, distance between the lamp and the plant, and exposure time directly affect the health of the foliage.
Therefore, equipment selection should be based not only on design, but also on internal metrics that estimate the amount of effective light received by each type.
Interest in these systems has grown along with the popularity of tropical plants, which typically require greater light intensity than other varieties. Without a stable light source, Its leaves may exhibit color changes, loss of firmness, and irregular growth. This type of signal is one that usually predicts that natural lighting is not enough and is necessary to complete the environment.
measurement PPFD (Optical photon flux density) is one of the most important aspects in determining whether a lamp provides sufficient intensity. This parameter indicates the number of photons useful for photosynthesis that reach the surface of the plant in one second. Their analysis allows you to compare models, regulate distances and avoid excesses that can damage the foliage.
the LED lights are usually the most recommended option Because they focus their spectrum in ranges useful for plant processes. Models designed for horticulture include combinations of white, blue and red light that facilitate the growth of leaves and stems. In this way, unnecessary wave emissions that can increase the temperature and cause heat stress in sensitive plants are avoided.
phenomenon Burning of leaves due to excess artificial light It is related to both distance and light intensity. When energy exceeds the species’ needs, leaf tissue cells are damaged and yellow or brown areas appear. This process can be progressive and is not always recognized on first exposures.
Ignition times also affect the result. Most houseplants require between 10 and 14 hours of light daily To maintain the photosynthesis cycle. Too long exposure can disrupt biological rhythms and cause unnecessary wear. Therefore, it is recommended to use timers that provide regularity.
The choice of lighting system depends not only on the lamp, but also on the characteristics of the space. Requires large rooms with high ceilings or dark walls More power for uniform lighting. On the other hand, closed sectors allow working with less intensive equipment without compromising plant growth.
Tropical species – such as monsteras, philodendrons or calatheas – typically require moderate levels of PPFD to support their leaf structure. These items They appreciate diffused and stable light, without peak intensity. In contrast, plants Succulents or cacti bear higher values And respond better to direct artificial light sources.
