With more than 35 years around plants and 20 years in the hydroponic industry, Simon Hart lives to garden. When not working on product development at Grotek or traveling the world to help clients get the most from their plants, he can be found in his green spaces. With indoor growing at work and at home, a small urban garden and a 3-acre food forest, Simon is always enjoying the science of plants and relaxing in the garden.
