Canadian Hydroponic Farm has a Drive-Through for Fresh Vegetables | A converted school in Saskatchewan is being used to grow fresh produce all year long. Vegetables have a short growing season in Saskatchewan, unless the farm is indoors in a controlled climate. A very unique farm in Hudson Bay is growing fresh, pesticide-free, produce all-year-long in a hydroponic farm (the plants are grown in water and not soil) and housed in a converted school building. But that’s not the only thing that makes Let-Us Grow Hydroponics one-of-a-kind. The first year of growing vegetables was a learning curve.
