Alexey Kovnerchuk and Taisia Melekh converted a balcony mini-garden into a 250-square-meter city farm in Yekaterinburg, specializing in growing microgreens, salads, basil, mint, and edible flowers. They have patents in plant cultivation automation and vertical farm lighting and supply various businesses such as supermarkets, restaurants, and hotels. Despite challenges with sanctions and importing seeds, they have adapted their logistics and use a rock wool substrate to eliminate the need for agrochemicals.
