Photobio Phantom Advanced Quantum Par Meter molasses These durable and reusable plasticPAR is the light that drives photosynthesis in plants. Measured on a quantum scale, PAR light ranges from 400 to 700 nm. However, the region brightest to human eyes is the area of least effect on plants, which is why the quantum par meter measures PAR light. This way you can make sure your plants are getting the right amount of the light they need to thrive. Measures photosynthetic active radiation (PAR) from 400 700 nm. Range of 0 to 10,000 umol.
