In this video, Widya Discovery takes viewers to a tulip farm in Europe to see how tulips are grown using hydroponic systems in greenhouses. The tulip bulbs are first arranged in a seeding medium and then moved to a cold room with water mixed with calcium nitrate. After two to three weeks, the bulbs sprout and are transferred to the greenhouse. The flowers are harvested based on the size of their petals and go through sorting and packaging processes before being distributed to consumers.
