In a Stoney Creek neighbourhood among the auto shops and packaging plants is an unconventional farm of little fish and baby lettuce plants.
Behind a sweaty glass door is a new business that takes a sustainable approach to farming fish and growing produce.
Tim Alford, along with high school friend Al Mastroianni, operate A&M Aquaponics, which farms tilapia and uses the fish waste to fertilize the various plants.
"There has never been a 12-month organic procedure before in Canada," said Alford.
Aquaponics is a system that combines aquaculture — raising of aquatic animals — and hydroponics — raising plants in water.
"It's an enclosed ecosystem," Mastroianni said. "When fish breathe, they exhale ammonia and that goes through a filter and breaks down into nutrients for the plants."
Farm could produce hundreds of pounds of fish per week
The two 25-year-olds from Hamilton are taking a chance, dedicating their time and money to a unique business they strongly believe in.

Water flows through a PVC pipe into a tank that's designed to pull the fish waste through to a filter. The water passes through a tub of bioballs, small plastic ball for bacteria to colonize on. The filtered water then moves through another pipe to feed and fertilize the plants. The system also keeps the water constantly clean for the fish.
At full capacity, Alford estimates they can produce 350-450 lbs of fish per week and 200-300 heads of lettuce, or other leafy greens, per day.
"Because with lights running 24/7, the plants can have what they need all the time," Mastroianni said. "They'll grow faster than being in a greenhouse or outside in a traditional farm."
Alford and Mastroianni's business partnership started with a message on Facebook.
"Al originally sent me a link for a farm [for sale] and the message said, 'Buy me this,'" said Alford.
'People were looking for locally-grown stuff (at Walmart) and we just don't have it'
Mastroianni's interest in aquaponics spawned from the "one thing I took from my education" taking undergraduate economics classes at McMaster University.
"In North America, we spend about 15 per cent of our income on food. Countries in Europe are spending upwards to 30 per cent and in Asia about 40 to 50 per cent," he said. "As their incomes catch up, our food prices will drive up."
Economic benefits aside, Mastroianni has no doubt their operation will take off. His confidence comes from a former part-time job at Walmart.
"Working in the produce department, people were looking for locally-grown stuff and we just didn't have it," Mastroianni said. "The market is there for it."
Since he approached Alford to be his business partner, it's been a labour of love for both. Alford and Mastroianni are investors one and two in A&M Aquaponics, along with a third anonymous investor.
A&M Aquaponics to sell at farmers' markets in May
The pair built the set-up from the ground up. Along with help from Mastroianni's father and brother, they constructed the floor-to-ceiling structure with tubs, tubes and filters with their own hands.
"Tim helped," Mastroianni said with a laugh, their long friendship evident.
The two aren't making any money yet - they just moved into their current space in December and turned on the system about two weeks ago — but A&M Aquaponics is set to sell at several farmers' markets starting next month, including Ottawa Street, Ancaster and Dundas. Their stand will be filled with a variety of lettuces, spinach, kale and arugula to start, and tilapia will be available come the fall.
Alford said everything will start sinking in once their first fish crop is ready to be sold, but Mastroianni is already amazed by what they've accomplished.
"When I first started researching aquaponics, I thought I'd do it on a small scale just growing for myself in the basement," he said. "But the fact I can do this for a living is amazing."
