The Effect of Light Spectrum on the Morphology and Cannabinoid Content of Cannabis sativa L.

Abstract. Cannabis sativa L. flowers are the main source of Δ-9-tetrahydrocannabinol (THC) used in medicine. One of the most important growth factors in cannabis cultivation is light; light quality, light intensity, and photoperiod play a big role in a successful growth protocol. The aim of the...

I stumbled across this recently. Although I don't have any use for it as I only can grow indoor. There might be some information in here that could help.
