24 hour lights
The majority of nutrient uptake and distribution happens during the dark period. This has been observed in almost every single terrestrial plant ever tested. It has been repeatedly tested in my food production sheds with monitoring probes checking the nutrient solution 24/7. The greatest amount of nutrient and water uptake happens during the dark period across every crop, from radishes to lettuces.
