What is a "Spectral" PAR Meter
Valentine’s Day is approaching, and you're an anxious indoor rose farmer trying to encourage your buds to bloom in time.
The good news is that researchers have begun to understand the triggering mechanisms for seed germination, flowering, and fruiting, involving grow-light strategies
Now indoor farmers are using this information with “Spectral” PAR meters, measuring grow lights for a light metric PSS (Phytochrome Photostationary State) to trigger photomorphogenesis (i.e., plant transformations caused by light).
