Feature
●Test the PAR of grow lights accurately for any light spectrum. The sensor inside is from a famous Japan semiconductor company. Search "compare" in Q&A to see the comparison between VBR-Plant and other brand.
●Show the PAR of the blue, green, and red in the light seperately. General Guides for the ratio of Red and Blue light for seedling(1:3), vegetative growth(1:2), and flowering stages(2:1 to 3:1).
●Logger 400 historical PAR data. Record DLI for 28 days. DLI can quantify the total amount of PAR received by a plant over the courese of a day.
●Up to 9999umol/(㎡s). The telescopic rod inside the package can help to test PAR at the top of plant, or PAR above the distant plant.
●Long time use. 3 AAA can be used for more than 100hours.
Description
Blue light is efficiently absorbed by plant chlorophyll. Red light is conducive to the growth of flowers and the maturation of fruits.
Understanding PPFD of Red and Blue seperately helps us better adjust lighting conditions to meet the needs of plants at different stages of growth.
VBR-Plant use the PAR sensor IC close to Photosyntically Active Radiation.
Easy way to judge if it is the par sensor, other than a light sensor, beacause we can show the PAR for Red, Green, Blue seperately.
