Greenhouse Lighting: Measuring with the WaveGo

LED greenhouse lighting has become a necessary supplement to natural sunlight for growers and greenhouse farmers worldwide. These lights enable growers to extend the day and grow crops year-round.

The proliferation of LED lights has given way to research focusing on the effects of the colour spectrum on crops. Ongoing research suggests that an ideal light spectrum for plants exists and that it changes throughout the plant growth cycle. With the ability to control the colour of the LED lights, growers can dictate the total power emission per colour reaching the plant and, by extension, the plant’s growth behaviour.

Traditional PAR sensors only measure total optical energy from 400-700 nm. They can neither be used to control the colour scheme, nor measure outside of this wavelength range. The ability to accurately measure the light spectrum reaching the plant at a wide variety of wavelengths is critical. This enables growers to dynamically adjust both the light power and colour to match the optimal scheme for that plant at that moment in its growth cycle.

The WaveGo handheld light measurement system is a handy option for taking quick measurements at different locations in a greenhouse. With one click, the WaveGo collects both PAR and spectral data. The WaveGo connects easily to a smartphone and stores data in the cloud. Results (PAR and PAR bins) are available in real-time from the WaveGo app on your phone and can be reported via email.

Greenhouse operators use spectral data measurements to adjust lighting schemes in real time to optimize efficiency – the WaveGo is here to help.

The WaveGo offers handheld spectroscopy powered by your smartphone for quick, easy, and accessible spectral light characterization.
