What makes Jianyi’s vegetables at Freshpal Farms so unique isn’t only a matter of taste: it’s how he grows what he loves. Jianyi cultivates vegetables 12-months of the year in a passive solar greenhouse – a greenhouse powered 100 per cent by the energy of the sun. Whereas conventional greenhouses rely on fossil fuels and artificial heat to warm through the winter, a passive greenhouse relies only on the sun. Jianyi runs the largest commercial passive solar greenhouse in Alberta.
Passive solar technology works to trap and store solar energy. Solar energy is released slowly to heat up the greenhouse, which creates optimal growing conditions so Jianyi’s thin-skinned tomatoes can thrive year-round – even in one of the most bitterly cold growing zones on the planet.
