TESTIMONIALS

“We use Horti Line nutrients in our fully enclosed, pesticide-free, carbon-negative pilot hydroponic system, where we grow living lettuce, spinach, arugula, chard, and kale for local stores in Penticton, BC. I have been gardening for over 50 years and hold a Bachelor of Science degree with extensive studies in biology. For the past 15 years, I have focused on sustainable agriculture. I can wholeheartedly say that the plants respond beautifully to Horti Line — with strong roots, excellent colour, and consistently outstanding flavour. Multiple customers have told us these are the best greens they have ever tasted. Horti Line offers exceptional value and has become a foundational part of our sustainable production system.”
