With white light what settings lead to the maximum oxygen production

With white light what settings lead to the maximum oxygen production-Another way to make white light is to coat the bulb lens with a phosphor compound Such bulbs usually use a blue light which hits the phosphor and it produces white light This is similar to the way florescent bulbs work White LED bulbs would seem to be the best alternative but there is a catchThey also found that blue light produced darker green leaves than natural light, whereas green and yellow light produced light green leaves A 12 study published in Scientia Horticulturae investigated the influences of three different qualities of light on lettuce They used a red and blue LED;

Not all seeds have the same light requirements Most seeds germinate best under dark conditions and might even be inhibited by light (eg, Phacelia and Allium spp) However, some species (eg, Begonia, Primula, Coleus) need light to germinate (Miles and Brown 07) Don't confuse seed light requirements with what seedlings needProduction with an increase in light intensity since light is required to fuel the photosynthesis process This seems to be the overall result since we observed an increase in O 2 production between our room light intensity with both the 3160 lux and 5150 lux light treatment This is interpreted as an increase in the photosynthetic rate per cellLightEmitting Diode (LED) Other materials are being developed that will allow fabrication of blue and white light LEDs In addition to making possible a wider variety of indicators and toys with more colors, blue light is preferable for some applications such as optical storage and visual displays We want to set up a manufacturing

A crucial component in the growth of a plant besides water and oxygen, is light By receiving it, a plant is able to convert sunlight into nutrients that it can use This process is called photosynthesis Water, oxygen, and sunlight make the holy trinity for plants Visible light is part of the electromagnetic spectrumPhotosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energyrich organic compoundsOxygen levels remained at 2% until about 750 million years ago (mya) From 750 mya until the now there has been a significant rise to %Oxygen generation also allowed the formation of an ozone layer (O3) Ozone shielded the Earth from damaging levels of UV radiation This, in turn, lead to the evolution of a wider range of organisms
