In Episode 21 of the GroShow Podcast, host Riley Jones is joined by Grodan Crop Specialist Jon Jirikovec and Anders Peterson and Michael Williamson from PIPP Horticulture for part two of a special mini-series with the Cultivation Elevated podcast.

If you caught part one on Cultivation Elevated, you’ll recognize today’s guests — and the ongoing collaboration between Grodan and PIPP Horticulture behind this mini-series. In this episode, we take a deeper dive into vertical cultivation: how smart facility design, irrigation planning, and substrate strategy all work together to support crop success at scale.

From optimizing airflow and drain layout to aligning media choice with multi-tier systems, Jon, Anders, and Michael share practical guidance drawn from years of fieldwork and facility builds. We explore the real-world challenges of vertical growing — including common mistakes, irrigation missteps, and how to avoid dry-back or pooling issues in tightly stacked environments.

You’ll also hear why infrastructure decisions upstream can directly shape root zone performance and crop consistency downstream, and how early planning can pay off in efficiency, yield, and long-term ROI.

Whether you’re designing a new facility or optimizing an existing one, this episode offers grounded, experience-driven insight from two teams who’ve helped shape the future of vertical cannabis cultivation.

In Episode 20 of the GroShow Podcast, host Riley Jones welcomes Grodan Crop Specialist Jon Jirikovec for a deep dive into one of the most important (and often underestimated) parts of a successful grow: initial substrate saturation and rooting strategy. From troubleshooting dry-back issues to dialing in daily irrigations, Jon shares the foundational practices that help cultivators get the most from their Grodan blocks and slabs. 

What if inconsistent rooting or poor substrate hydration are limiting your yields without you even realizing it? Jon breaks down proper saturation techniques that create uniform water distribution, why early irrigation decisions shape root structure, and how to avoid common mistakes like using low EC or skipping QC checks on block weights. 

We also explore how to maintain capillarity during the rooting-in phase, why sensors should be placed strategically, and how overly wet or dry conditions can throw off nutrient balance in the root zone. Jon outlines a multiphase irrigation approach—refreshment, drain, and dry-back—that sets growers up for long-term consistency, crop steering, and improved plant health. 

If you're building out a facility or looking to refine your early-stage irrigation protocols, this episode offers clear, actionable guidance grounded in real-world experience—and shows why so many top growers trust Grodan stone wool to set the foundation for success.
