Aquaponics could be the farming of the future. It's a way of farming without any dirt. The plants are put on a floating platform on water. Fish in the water fertilize the plants, and the plant clean the water.
"We're able to grow things on a commercial scale with about 90 percent less water than traditional agriculture," Applied Sciences Paul Nickerson said. "It's a great field for adapting. We can do it independent of soil."
At the Farm Show a greenhouse display was in the expo for the masses to see.
"People all over the state and all over the country and different countries have been through this system this week," Jump Street's Bob Welsh said.
He helps with the School to Table program. The program helps to put the greenhouses at schools. Once there, the students raise the plants and sell the crops to local restaurants.
"This is the new age, the next generation of agriculture and the kids are eating it up," Steelton-Highspire High School Principal Mick Iskric Junior said.
"We sell to restaurants locally, here in Harrisburg," senior student Ilaynna Brown said.
The school plans to continue to grow their greenhouse and make enough food to use in their cafeteria.
