WebThe results suggest the following. (1) Different algae show different responses to high oxygen concentrations and high light intensities. (2) Inhibition of photosynthesis (CO2 fixation and growth), if seen, increases with increasing oxygen concentration and with increasing light intensity (at light intensities greater than saturation). WebThe light quantum density of this LED plant lamp achieves high intensity light and can reach the light saturation point of the plant, thus providing and promoting photosynthesis to achieve the ideal growth state. New efficient chips are used to provide even light and stronger light transmittance, making plants grow healthier and stronger.
