Plants on a hot dayTo get essential nutrients from the air like oxygen and carbon plants have stomata. Stomata are like noses for the plants, allowing them to breathe. Plants can open and close stomata depending on how much carbon they need. The problem with keeping stomata always open is that the plant loses water when the stomata are open. Plants are continually trading water for carbon. The hormone that closes stomata and tells the plant that there is a drought is abscisic acid. Abscisic acid also sl
The Impact of LEDs and Plant Growth - What is Fact and What is Fiction?
Fact: When the light-emitting diode (LED) bulb was invented, in the early 1960’s, this new light source was expected to be a more efficient way to light a room. What was not anticipated was the huge impact this light source would have on plant growth. And, while most people believe, LED bulbs are, in fact, lifesavers to plants, other people still believe LEDs are expensive and unnecessary.
Fact: Also discovered was that the photons in the LED bulb had the capability of becoming absorbed by a plant’s chlorophyll, which was responsible for plant growth by creating light in both the blue and red wavelengths. Absorbed by the chlorophyll in plants, these wavelengths have, by far, the greatest impact on photosynthesis, leaf development, and flowering.
