麻豆影院

Drivers on U.S. Hwy 36 zoomed past a new sight at Williams Village this spring 鈥� a vibrant purple glow emanating from the second floor of the complex鈥檚 Village Center dining hall.

The source was CU 麻豆影院鈥檚 newest and perhaps most unusual greenhouse, a 3,000-square-foot facility on site that can grow as many as 6,000 plants at once and is on track to become the primary source for the dining hall鈥檚 greens.

There鈥檚 no dirt here: The plants are housed in 137 eight-foot-tall hydroponic grow towers that deliver water and nutrients to the plants without the need for soil. The greenhouse climate is a steady 65 degrees during the day and 55 at night. Lights automatically turn on as sunlight dims.

鈥淲hen you see something being grown right in front of you, you have more appreciation for your food,鈥� said CU farm manager Alex Macmillan.

The greenhouse provides lettuce, kale and arugula for the Village Center salad bar and chefs. Each tower yields up to three pounds of food each month. If there鈥檚 surplus in the future, the extra greens will be available to other CU dining halls and campus catering units.

鈥淣othing gets wasted here,鈥� said Macmillan, the sole farmer for the greenhouse. 鈥淭he appetite for greens at CU is pretty crazy.鈥�

When students are on summer break, he鈥檒l experiment with basil, dill and parsley.

He was pleased with his first small batch of crops, in March 鈥� about 35 pounds of food in all. He initially grew the greens in small, spongy, foam cubes in the greenhouse, then moved them to the grow towers, where they bathed in continually circulating water and fertilizer. After about a month, it was all ready to eat.

鈥淭he kale is getting out of hand,鈥� he said in April, pointing to the flourishing towers. 鈥淎nd the arugula has gone wild on me.鈥�
