Optimizing Photoperiod Switch to Maximize Floral Biomass and Cannabinoid Yield in Cannabis sativa L.: A Meta-Analytic Quantile Regression Approach
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8786113/
From the abstract:
"Floral biomass was maximized when the long daylength photoperiod was minimized (i.e., 14 days), while
THC and CBD potency was maximized under long day length photoperiod for ~42 and 49–50 days, respectively. Our work reveals a yield trade-off in
C. sativa between cannabinoid concentration and floral biomass where more time spent under long-day lighting maximizes cannabinoid content and less time spent under long-day lighting maximizes floral biomass."
Interesting for photo plants. Are there implications for autoflowers?
