Red and blue grow lights

Colors below 000K are known an warm colors ( red ). The spectrum of light is important to horticulture because each spectrum triggers different responses from the plants — blue light induces vegetative growth , red . That being sai you can find more info on red light vs. Suffice it to say, that so far, all the pigments identified in green plants absorb light wavelengths in the UV, blue , red and far- red regions of the light spectrum while ignoring (or avoiding!) the green and yellow regions. We could say that the two most important light colors to be placed in an LED lamp are: red and blue.

Red is the main component needed for photosynthesis and stem elongation inhibition.

Additionally, it signals to the plants that there are no other plants above it and that it can thus have uninhibited .

Which is better for vegetative growth? Instinctively, the answer might seem obvious: Blue light is for vege! That basic mantra has been plastered all over the internet. If something so simple in terms of plant requirements is clearly wrong, how then can we be . Red spectrum light is required more when your plants are flowering and fruiting . By designing an indoor grow light using diodes, specific wavelengths of light can be produced.


Light is all around us every day. Findings showed that plants are affected by light in the red , green and blue parts of the visible light spectrum. I do some consulting work regarding grow lights and design for the University of Florida Horticulture LED Research.


Deep Blue and Deep Red have always worked . Free DC Female Connector, UK Stock. Red : Blue =5:or 4:,Emitting Color: Red Blue . Since photosynthesis is preferentially driven by specific bands of red and blue light, LEDs offer the opportunity to provide energy of the required wavelengths without wasting any . There are LED lights for growing that are designed specifically for vegging your plants ( blue shifted lights) and LEDs for flowering your plants ( red spectrum lights ). We grow plants with white, red and blue light and compare the growth. You might think of phytochrome as an eye that only senses red light. In fact, many plants can actually grow even if they only get pure red light, though they won't grow as big or as healthy as they do under full spectrum light.


Red light can convey caution or danger or stopping at intersections, but for plants red light is highly effective at regulating growth and development. LED grow lights is used for higher . Within the photosynthetically active waveband (4to 7nm), sunlight emits roughly similar amounts of blue , green and red light. This waveband is within the visible spectrum, has relatively high energy, and has pronounced effects on plant growth and flowering.


Our perception of blue light , especially at shorter wavelengths (for example, 4to 4nm) is low compared to green. In contrast, blue light is considered equally effective as green or red .
