Climate, Cold & Container GrowingDoes matching lamp output reproduce the whole daily light supply of a mango greenhouse?
Sunlight and supplemental fixtures both contribute, and their contributions change through the season. Record their combined delivery at canopy level instead of treating the lamp schedule as the complete light environment. Two houses with identical fixtures can receive different daily totals because of glazing, structural shade, and weather. Compare those totals before attributing different growth entirely to fertilizer.
