    175: Advanced Aeroponics & Why Vertical Farming’s Future Lies in Glasshouses

    Are you curious about the latest innovations in sustainable agriculture? I recently caught up with Charlie Guy, CEO of Let Us Grow, to discuss the fascinating world of advanced aeroponics and its potential to revolutionize greenhouse farming. Charlie shared insights on Let Us Grow's journey from vertical farming to focusing on aeroponics technology for greenhouses. He explained how their advanced aeroponics system offers significant advantages over traditional hydroponic methods, including increased yields, improved plant health, and reduced water usage. Charlie also touched on the company's expansion into global markets and their efforts to educate both industry professionals and the public about the benefits of controlled environment agriculture. We delved into the challenges faced by the vertical farming industry and how Let Us Grow has adapted to changing market conditions. Charlie emphasized the importance of collaboration within the industry and highlighted their partnerships with established greenhouse builders and system integrators. He also discussed their community outreach efforts, such as the Bristol Basil Company initiative, which demonstrates the potential of local food production using advanced growing techniques. Throughout our conversation, Charlie provided valuable insights into the future of controlled environment agriculture and the role of aeroponics in creating more sustainable and resilient food systems. If you're interested in the intersection of technology and agriculture, or simply curious about where your food comes from, this episode offers a fascinating glimpse into the cutting-edge world of advanced growing methods.

It doesn't make sense from an environmental standpoint to burn fossil fuels to convert them into electrons to power lights to grow plants when the sun is free.""We're showing you can turn disused greenhouses into productive grows that are profitable and give back to your local food community. You can achieve many of the same outcomes as vertical farming with a slightly lower tech structure like a greenhouse, while still growing the best produce year-round with the least water."Resources MentionedWebsite - www.lettusgrow.com LinkedIn - https://www.linkedin.com/company/lettus-grow Facebook - https://www.facebook.com/LettUsGrow/ Instagram - a...

    174: The Hidden Power of Steam in Indoor Farming

    Are you struggling to maintain soil health and reduce costs in your indoor farming operation? Soil steaming technology might be the solution you've been searching for. In this episode, I speak with Hans Kristian Westrum, Chief Strategy Manager at Soil Steam, about their innovative soil steaming technology. Hans grew up on a farm in Norway and later pursued a career in business before returning to agriculture. His company, Soil Steam, has developed machines that use steam to sanitize soil and substrates, eliminating harmful pathogens and weeds without chemicals. We discuss how Soil Steam's technology evolved from open field applications to containerized solutions for indoor farming. Hans shares insights on how their machines can effectively treat substrates, allowing farmers to recycle growing media and reduce costs. Recent trials with strawberry growers in Belgium demonstrated that steamed, recycled substrates performed as well as new substrates, opening up exciting possibilities for sustainable farming practices. The conversation also touches on the challenges of balancing different market demands, from construction projects to indoor farms. Hans emphasizes the importance of focusing on containerized solutions to meet the growing needs of indoor farmers worldwide. We explore future plans for expansion into North America and the company's commitment to participating in industry conferences to share their research and technology.

If you have one disease in that coco coir or whatever you get, if something can happen, it means it comes from Sri Lanka and it can go by boat, what happens all this distance.""We got rid of the harmful organisms that were there and the natural life was back two weeks after. It comes from surroundings, from the soil beneath and stuff like that.""I think it's a fantastic combination. You can talk about sustainability, but if there's no saving money, it's impossible.
