VDL PAR Meter (0-3999 µmol/m²/sec)

Do you know if you're giving them enough or too much light?

The PAR meter is designed to measure PAR (photosynthetically active radiation) flux at wavelengths between 400 and 700 nm. There is a proportional relationship between the number of photons absorbed in the 400-700 nm band and the photosynthesis rate in plants, which is important for horticultural studies and monitoring plant physiology.

Its small size allows you to take in-situ measurements of your crops without having to carry bulkier or heavier equipment and to know how much light energy your plants use for photosynthesis.
