Nik from Rooted Leaf Nutrients (use code GROWCAST) returns for another deep dive- this time moving away from soil fertilizer elements and delving into watering dynamics. Nik introduces us a concept called SPAC, or soil, plant, air, continuum (AKA the soil, plant, atmosphere continuum). This concept encompasses a more holistic view when it comes to optimal climate conditions in our cannabis grows- whereas singular metrics like VPD can sometimes be only part of the picture. Nik discusses how we should be thinking about what happens to all that water that we dump into the soil system after we put it in there... Plants, after all, are just water lifting mechanisms designed to move that water from the soil into the atmosphere. Understanding and mastering this cycle leads to a healthier, and more vigorous garden.

Can we actually use cannabis plants to uptake precious metals like nickel and maybe even GOLD using the power of bio-accumulation? Spectacular brand new guest Song Jin from Gaia Technologies joins the program for an absolutely incredible episode about microbes, mineral solubility, soil remediation, and more. Song talks about his journey from environmentalism work into plant health and fertilizer, and eventually what led him to create Ginate digest humate products. Song discusses some of the incredible work he now does, including his recent trip to DC for a phyto-mining summit- where they are researching how to use hyper accumulator plants to actually extract precious minerals from the ground by using a special microbial metal solubility enhancer, and process the metal out of the harvested plants. Can you imagine using cannabis to mine gold from the ground?

GROWCAST CULTIVATORS CUP! APRIL 12TH, VIRGIL ILLINOIS: Grab your tickets today before they sell out at www.growcast.com/events  The incredible Dr. Riley Kirk from Bioactive Podcast and so much more is here on the program for the very first time! Dr. Kirk tells us all about her extensive background in studying plant medicines, and what led her down the path of educating patients and diving into cannabis research. Riley shares some of the findings she's discovered through her extensive personal study and research, and enlightens home growers on how to more accurately think about things like flavor and aroma. Riley talks about the complexity of the human palette, and how so many different compounds play into the taste and aroma experience- not just terpenes. This leads to a larger conversation about the broad category known as flavorants, and how some of the lesser known compounds can create some of the most unique and noticeable flavors.

GROWCAST CULTIVATORS CUP! APRIL 12TH, VIRGIL ILLINOIS: Grab your tickets today before they sell out at www.growcast.com/events  Mike from www.growwithgrease.com joins the program for the first time to discuss how to incorporate specific hormones into your garden to boost your yields significantly. Interestingly, Mike shares his story which coincides with our last guests background as well- Mike was also one of the co-founders of the now defunct Mammoth Microbes. He expanded his work into his own brand, Grease, and now deals in soil conditioners, ferments, additives and more. Mike breaks down exactly how the hormone Triacontanol triggers your plant into producing up to 20% more flower weight- and how additives like these differ from other bottled products. Mike also shares more information about his love of applying cannabis and trichome ferments to his own garden, and how feeding the plant back to itself can produce major benefits. You can use code GROWCAST at www.growwithgrease.com for 10% off.

Dr. Colin Bell - formerly of Mammoth Microbes and currently working with the incredible Miim Horticulture - returns to the show! Today we are doing a microbial deep dive in an attempt to understand what is essentially a massive iceberg of microbe knowledge. We only know a brief portion of how powerful and influential micro organisms are, but every year we are understanding more and more about how bacteria, fungi, and other tiny beings shape the world around us. Colin gives us a great breakdown of how microbes work from a basic perspective, how they interact and communicate with plants, and eventually dives deep enough to explain that just about everything to do with the human experience is powered by the microbiology within our own human microbiome. Even plants themselves, may have evolved from collections of ancient bacteria- thus it is crucial to understand and employ more of these tiny organisms in our own home gardens!

Pest expert Matthew Gates is back, and this time you're in for a doozy! The boys start the show by discussing a recent infestation in Jordan's garden, of a pest that is seemingly less common in indoor spaces: leaf miner type insect pests. Often confused with thrips damage, these particular pests need to be approached with a totally different strategy, and Jordan shares his non scientific trial of spraying down his plants with an abundant solution of living nematodes. The conversation turns to powdery mildew- which is one of the oldest, most ancient, fast spreading, and adaptable plant pests on planet Earth. Not only do these intelligent species of fungi adapt their genes to resist your attacks as a farmer, but they can mutate and adapt in as little as a few weeks. Also, the fact that PM relies on similar pathways as beneficial fungis like myco, may point to a hint that PM was once a beneficial, who has since gone rogue and turned to the dark side. If it's true, as many mycologists theorize, that fungi can survive space travel, and may have been some of the first life to land on this planet via asteroid, then this enemy your dealing with is a truly ancient, and highly intelligent one.

OKCalyxx returns to the show for a winter update about everything he is doing to prepare for the big thaw! Calyxx shares the story of how he's kept his same vegging plants alive through the entire winter- even though his grow shed is literally freezing over currently due to the extreme cold. He talks about growing big plants outside, and how he plans to take these to full term until the 2025 harvest. OKC also updates us on his breeding projects, where he is still continuing a lot of his current work- but also incorporating more funk into his genetic pool. We wrap up the show by teasing one of the greatest grow classes of 2025, the Autumn Natural Farming Immersive.
