    Grow Your Sustainable Future with Proven Winners

    Sustainability and environmental responsibility are high on the priority list for the Proven Winners team and their partners. Their new Eco+ plastic-free and industrial compostable pots are a key part of this plant powered package. Host Bill Calkins caught up with Proven Winners’ director of sales, Dave Konsoer and Danny Mishek, president of VistaTek—the award-winning manufacturing company behind the new pots and other plant-based, compostable products making their way into many industries. Danny, Dave and Bill discussed all aspects of the new packaging from manufacturing and trialing to ensure integrity in greenhouse environments to seamless integration into crop production systems and the strong, branded retail presence for which Proven Winners is known. Dave clearly explains the reasons Proven Winners invested in the move to sustainable packaging and Danny articulated why a zero-plastic approach is not only responsible but becoming necessary due to new regulations being implemented in many states very soon. Of course, the pots went through many iterations in development and functionality in greenhouse production and retail settings was non-negotiable and Dave stated there are no changes to how crops are grown in Eco+ pots and the brand messaging remains crisp and clear on the plastic-free material. Danny explained regulatory changes coming quickly in many states and why bio-based materials and plastic-free pots like Proven Winners’ Eco+ will help growers stay ahead of “extended producer responsibility” laws. Plus, as Dave explained, consumers clearly want responsible packaging and look to Proven Winners as a leader in the gardening space. The company’s social media pages for gardeners are filled with positive comments about the new plastic-free packaging. There’s so much fantastic information in this podcast and excellent discussion around the topic of sustainability. It’s steeped in real-world horticultural knowledge of supply chains, price sensitivity, production situations, tolerance for change and future plans. You really have to listen all the way to the end because the ideas and info just keep coming.

    Grower Math: Greenhouse Cost Accounting ft. Stephen Steiner

    Cost accounting is the process of calculating your fixed and variable costs of production and identifying on what products and activities you are spending your resources. It may not be glamorous, but taking the time for cost accounting can dramatically improve your business’s profitability. Ball Seed’s senior business analyst Stephen Steiner joins host Bill Calkins for a quick crash course in “grower math.” Stephen discusses simple ways to calculate costs (fixed and variable) by sharing greenhouse production-based examples. Knowing the true cost to produce various inputs will help you and your team make the smartest—and most profitable—decisions. WATCH THE VIDEO! This discussion is a condensed version of a much more in-depth presentation you can find HERE. Stephen also recommends a series of GrowerTalks’ articles digging deeper into greenhouse cost accounting from many angles. You can find all of these resources and more HERE.

    The Power of Seed ft. Josh Kirschenbaum

    Warning: You’re going to hear the word SEED a lot in the next half hour or so, because our guest this episode is Josh Kirschenbaum, the seed supply manager at Ball Seed Company. He’s a seed guy all the way. In previous roles, Josh was PanAmerican Seed’s business and portfolio manager for the company’s vegetable lineup and before that was product development director at Territorial Seed Company in Oregon.   Here’s what you can expect from host Bill Calkins and Josh this episode:   Their shared fascination with the new OPEX Perfect Pick machine Ball introduced earlier this year. Josh describes it as a climate-controlled vending machine for seed packets that can pull 20 orders at a time, resulting in speedy service and increased accuracy in order fulfillment. (Check out the video and article link in the resources below to see the machine in action.)   Bill challenged Josh to come up with three reasons why seed solves problems and why it’s still a preferred way to produce crops. Josh explains the economic benefits, why flexibility and efficiency are optimized when starting from seeds or plugs and finally the amazing innovation and quality of genetics available from seed.   Throughout the conversation, Bill and Josh touch on many more aspects of seed crops that have been at the core of Ball’s business for more than a century. Josh discusses the global nature of our industry, how innovative breeding drives our future, the importance of quality seed in large-scale plug production and the legacy seed has in horticulture.   Resources:   Ball Seed Company Website: https://ballseed.com/   Ball Seed Product Forms & Premier Line Seed List: https://ballseed.com/Products/Seed   OPEX Perfect Pick—From Grocery Store to Vending Machine (Article): https://www.growertalks.com/Article/?articleid=27411   OPEX Perfect Pick (Facebook Video): https://www.facebook.com/share/v/19SiAULR35/

    The ABCs of Foliar Disease in Greenhouse & Nursery Crops ft. Janna from Envu

    This episode includes critical information for both nursery and greenhouse producers!   To discuss this episode’s topic, host Bill Calkins was joined by a fantastic guest from Envu—Dr. Janna Beckerman—who’s an experienced plant pathologist at heart and wanted to discuss three key diseases commonly encountered in greenhouse and nursery crop production. Conveniently for the podcast title, these diseases begin with the letters A, B and C—anthracnose, Botrytis and cercospora.   In this episode, the conversation starts with a brief recap of some diseases Dr. Beckerman saw a lot of in the spring, like rusts and Pythium and then the conversation moved quickly to the topic at hand—foliar diseases. Bill and Janna took the three ABCs in order talking through the main crops impacted by each one, symptoms to watch for and control methods. Although Dr. Beckerman mentioned one of Envu’s flagship fungicides, Broadform (a unique chemical class with two modes of action to control more than 50 pathogens), her rotation recommendations and application best practices were extremely in-depth and user-friendly. She also went through strategies to mitigate the risk from these three diseases using good sanitation practices and greenhouse and nursery environmental management.   Bill and Janna closed out the conversation with the importance of resistance management—a topic that cannot be overstated. Keeping our toolboxes full and giving all growers the best chance for controlling diseases (and insect/mite pests) requires diligence and intelligent approaches to chemical rotation and application.   You’ll want to listen all the way to the end of this episode, because Dr. Beckerman is a true expert and offers countless tips and tricks to help you and your production team up the game season after season.   Resources:   Envu’s Ornamentals Segment Website: https://www.envu.com/segments/ornamentals   Envu’s Products for the US Market: https://www.us.envu.com/ornamentals   Envu’s Products for the Canadian Market: https://www.ca.envu.com/greenhouse-and-nursery   Broadform Fungicide Product Information: https://www.us.envu.com/ornamentals/po/products/broadform

    Horticulture 2.0 (Part Two): Rethinking Our Industry with Jaime Kedrowski

    Host Bill Calkins asked Jaime Kedrowski (Marketing Manager at Ball Seed Company) to join him for a discussion about the short-term future of our industry. This conversation was recorded live at the 2025 Ball Seed Customer Days open house event in West Chicago, IL. For this episode, Bill had three “big ideas” that he introduced to Jaime one at a time to find out what she had to say about them (and if she had any even bigger ideas or approaches). There are no right answers and neither Jaime or Bill own a functional crystal ball. But the goal of this discussion was to share ideas to ponder and potential directions to steer as our industry enters a new era. Topics discussed: Horticulture vs. culture New plants vs. new solutions Lifestyle vs. hobby

    Plant Growth Regulators ft. SePRO’s JC Chong

    In this episode of the Tech On Demand podcast, brought to you by GrowerTalks, host Bill Calkins sat down with SePRO’s Technical Development Manager (and PestTalks e-newsletter editor) JC Chong to discuss plant growth regulators. PGRs are critical for greenhouse professionals but really haven’t been covered much on the podcast. Now’s the time! JC and Bill start off with a conversation about what PGRs are and what they do before jumping into a few specific products, including SePRO’s Topflor and A-Rest. Topflor is a gibberellic acid biosynthesis inhibitor (Class B)—active ingredient Flurprimidol. It offers some unique benefits in production, which JC covers in an informational way. JC outlines crops that respond particularly well (and some that don’t) and what you can expect from crops treated with the product. JC also explains some of the more common rates and application methods and a handy tool from SePRO to take a lot of the guesswork out of PGR application. JC is a researcher and has worked with the SePRO team and growers across North America to better use PGRs to achieve a variety of goals and has a lot of practical information to share. You’ll want to listen all the way to the end of this episode because when Bill and JC chat, you never know what to expect! WATCH THE VIDEO VERSION!
