We will try it here.
Open to all discussions on this topic.
I read yellow light (580–600nm) light appears to inhibit lettuce growth.
Does anyone know if yellow light has the same effect on cannabis?
[Dougher and Bugbee (2001) concluded that an increased proportion of ‘yellow’ light (λ580–600 nm) was responsible for a decrease in lettuce yield, perhaps due to suppression of chloroplast or chlorophyll formation, when comparing growth under HPS and MH lamps.
