Michael: Providing students with real, fresh, grown, nutrient dense produce... Is... is real pivotal to the learning.

Narr: Michael Jochner admits it's a very unusual way to farm, but says that technology and this shipping container are key to meeting the green salad lettuce needs for students in the Morgan Hill Unified School District.

Michael: Well, I think food sovereignty is important, um, especially in underserved communities.

And I wanted to demonstrate that a school district and not just large farming or small scale farming, that a school district itself could be the farm.

Narr: Michael has a background as a chef, and he's Morgan Hill's director of student nutrition.

The shipping container is called a freight farm and uses the vertical hydroponic farming technology developed by a Boston company.

It all takes place in a ten by 40 foot space.

Michael: So let me show you our nursery station.

This is where the lettuce and the seedlings start their life cycle.

All of our nutrients are stored here.

The computer pumps continually check the water, evaluate the EC readings, PH readings, temperature readings.

And at the end of the nursery station, we have a 40 gallon reservoir where all that water is stored.

Narr: Michael grows five varieties of lettuce, which germinate at the nursery station in small grow pods.

Nutrient dense water feeds the roots of the tiny plants.

Michael: Down on this floor, we start our seeds in the grow pods.

They'll spend two weeks in the humidity domes and at the end of the two week cycle, they turn in these beautiful little seedlings.

Narr: The freight farm at Sobrato High School is one of two in the district, each costing $150,000.

After sprouting, the seedlings moved to vertical growing panels called cultivation walls watered with drip irrigation.

Each farm container will grow 4000 small heads of lettuce at a time.

LED light walls powered by the high school's solar panels, provide the illumination for plant growth.

Michael: So leafy greens require specific light spectrum.

Crate farm uses red and blue lights in the cultivation walls.

This is our daylight setting.

We have over 100,000 LED lights and these lights will remain on for 14 hours of simulated sunlight.

So lettuce on this wall is now six weeks old.

Morgan Hill students get to enjoy living lettuce right from our walls.

We take the lettuce from the wal and unlike conventional farming, where you have to bend over, we simply lift the panel off the wall and we transfer the panel right to our nursery station.

Narr: Lettuce from the cultivation panels goes directly to lunchrooms in cafeteria salad bars.

Michael says the container farms produce the equivalent of two and a half acres of lettuce in just 320 square feet of grow space.

Raising their own has also helped the district reduce part of their spending on fresh produce.

For second graders Aida and Cody, It means a tasty part of their daily choices at lunch.

Aida: I always love salads.

I had tomatoes, salad, ranch, cucumbers, and plums.

Cody: I usually wait in line until it's my turn.

Then I go to to go to the salad bar and I pick what I want.

Dr. Garcia For a lot of our students, it's the only meal that they have during the day.

And so we take our school nutrition efforts very seriously to ensure that our students are eating healthy.

Michael: My dream is to ultimately try and grow the whole salad bar.

While ambitious, we decided to start with lettuce because the technology allowed us to do so.

Narr: Michael calls his future agricultural plans, farm tech.

It would utilize existing greenhouse facilities and the district's open space to develop curriculums and coursework.

Both would emphasize the nutritional and environmental benefits of merging technology and farming.

Michael: The district is sitting on several acres of land that has been set aside to see if we can build farm tech into a destination worthy field trip worthy location for both students and the community.

I'd like to show off the technology and show that its importance in a community is... is not solely reliant on conventional farming, that there are high tech alternatives.

Narr: But for now, the technology is providing daily evidence of the possibilities that come from finding new ways to help feed students and the community.

Michael: For me, it's really just been about the kids and watching them grow to learn real produce.

Dr. Garcia: If we begin with our students and teach our students the importance of healthy eating habits, those habits will stay with them throughout their entire lives, and it will pay dividends to ensure that our kids grow a healthy life.

Narr: There are now more than 600 of these freight farms located in every U.S. state, as well as 40 other countries around the world.

Besides lettuce and other greens, schools, nonprofits, farmers and even restaurants are now also growing radishes, strawberries and even flowers using the same hydroponic wall panels and artificial light.
