Plants treated with high nutrient level received complete Hoagland’s nutrient solution on a daily basis; plants treated with low nutrient level received complete Hoagland’s nutrient solution once a week.
PPFD under full light was at 600 μmol m⁻² s⁻¹; PPFD under shade was at 324 μmol m⁻² s⁻¹.
Values are means of six replicates.
