John Kohler is passionate about organic gardening, and this description may be a bit lacking. In fact, John is downright obsessed with finding ways to improve his crop yields in his Las Vegas urban farm (he was actually raided by police thinking he was growing marijuana) and his zeal jumps forth from his videos with conviction normally associated with the most ardent religious preachers. That said, we find almost every topic he covers relevant, even if his videos are a bit on the lengthy side, and John will eventually win you over with his sheer earnestness and honesty. Whether you want to start your first container garden, re-mineralize your soil, eliminate pests, or learn the benefits of different types of produce and how to properly compost, this is the resource to visit. So if you have a gardening question, visit him – now!
