In this episode, Matthew breaks down an upstream supply chain issue that many growers may not realize is affecting fertilizer manufacturing worldwide: sulfuric acid availability.
Sulfuric acid plays a critical role in producing many of the raw materials used throughout the fertilizer industry, including phosphoric acid, potassium sulfate, mono potassium phosphate, and other key ingredients. As global supply chains tighten and sourcing priorities shift, manufacturers may be forced to source materials from different suppliers, resulting in changes to consistency, particle size, impurities, and solubility.
Topics covered:
Why sulfuric acid is one of the most important industrial chemicals in fertilizer productionHow global supply chain disruptions can affect fertilizer manufacturingWhy some growers are seeing more residue and precipitation in stock tanksWhich fertilizer ingredients are most vulnerable to upstream sourcing changesWhat growers should watch for when evaluating fertilizer qualityHow quality assurance and analytical testing help maintain consistencyChapters

Most facilities make the same hiring mistake: choosing a head cultivator based on plant knowledge instead of leadership ability.
In modern controlled environments, success depends less on hands-on growing and more on managing systems, people, and performance.
This video breaks down:
Why designing around one cultivator is riskyWhat actually matters in a lead roleHow to avoid costly hiring mistakes -
Light interruption is one of the most overlooked risks in indoor facilities—and it often shows up after a build is “complete.”
In this breakdown, Egan O’Keefe (Co-Founder of Front Row Ag, VP of Cultivation at Story of Maryland) explains:
Why commissioning doesn’t end when the building is handed overWhere light leaks actually come from (doors, ductwork, equipment)How even small LEDs can impact sensitive varietiesThe difference between resilient vs. finicky geneticsWhy green aisle lighting is a safer—but not perfect—solutionThis is practical, field-tested insight for operators who want consistency, not surprises.

Purple expression is one of the most misunderstood traits in cultivation.
In this conversation, we break down why plants turn purple, when it’s genetically driven, and what actually happens when growers try to force purple expression through environmental stress.
Lower air temperatures, cold root zones, spectrum manipulation, nitrogen tapering—these strategies can increase anthocyanin expression, but they don’t come for free. Many of the same levers that push color also slow photosynthesis, reduce energy availability, and introduce yield or consistency trade-offs.
We also dig into:
Why genetics set the ceiling for purple expressionWhy chilling root zones is especially riskyHow spectrum shifts are often the least damaging optionWhere nutrient tapering fits (and where it doesn’t)Why environmental uniformity matters more than most people realizeHow microclimates inside a room can quietly wreck nutrient strategyThis is not a “how-to force purple” guide.
It’s a reality check on trade-offs, decision-making, and choosing the least damaging path for your operation.

High-performing commercial cultivation teams don’t improvise the day.
They start with a master production calendar, translate it into a short list of priority tasks, and use structured morning and end-of-day meetings to keep labor aligned and prevent drift.
This conversation breaks down how top-performing teams organize the day—from calendar to canopy—so work stays efficient, predictable, and repeatable at scale.
00:00 - Why the day needs structure
03:10 - The master calendar as the real decision-maker
07:45 - Limiting the day to a few priority tasks - Why top teams avoid overloading the schedule
12:30 - Morning meetings: setting direction, not micromanaging
18:20 - Labor flow and task handoffs - How experienced teams sequence work across rooms and crews
24:10 - End-of-day meetings: closing the loop

Most growers treat this crop as biologically unique. That assumption breaks more things than it fixes.
In this conversation, John Sokolik explains how well-studied crops like hops, tomatoes, hackberry, and lima beans reveal practical lessons about canopy density, light penetration, pest pressure, and plant defense signaling. Topics include leaf area index, under-canopy lighting, plant communication via jasmonic acid, and why some tissues become energy sinks instead of contributors.
If you want higher efficiency—not just more biomass—this is the lens to use.

Every time a plant is touched, there’s risk—and cost.
In this conversation, we break down why plant “touchpoints” matter more than most facilities realize. From disease pressure to labor efficiency, excessive handling quietly inflates costs and introduces variability across a crop cycle.
We walk through a simple exercise: counting planned plant touches from transplant to harvest—and show why many operations could remove entire steps by rethinking container strategy, trellising, and workflow design.
This isn’t about cutting corners. It’s about designing systems that need less intervention to begin with.

Outdoor growers are rethinking the seed vs clone decision—and not for the reasons you might expect. In this conversation, Front Row Ag’s technical team breaks down how modern seed genetics, crop scheduling, and early environmental exposure are changing what’s possible outdoors.
We cover:
Why seed-grown plants are now far more uniform than they used to beThe real logistical difference between seeds and clonesHow early hardening creates tougher, more resilient plantsWhat this means for large outdoor acreage and harvest consistency -
Front Row Ag Technical Specialist Tyler Simmons chats with founders Matt Curran and Egan O’Keefe about what’s actually working in outdoor cultivation at commercial scale.
In this conversation, the team breaks down real-world trends they’re seeing across commercial outdoor and mixed-light operations, including why many greenhouses end up costing nearly as much as indoor grows, how poor planning around light and infrastructure limits performance, and why smaller, in-ground plants are helping growers dramatically reduce labor and fertilizer costs.
They cover practical topics like greenhouse design mistakes, DLI planning, plant spacing strategies, labor logistics, soil and water testing, fertilizer efficiency, and how some operators are moving from $25–50 per pound down to $10–15 per pound in just a few seasons.
This episode is a grounded, field-tested discussion for cultivators navigating tighter margins, rising input costs, and the realities of large-scale outdoor production.

Front Row Ag formulator explains why our fertilizer is made with purified, prilled calcium nitrate. It provides stable nitrate nitrogen in “exceedingly high abundance,” supports protein formation, improves metabolic consistency, and avoids the volatility that can derail steering and crop uniformity.
Ammonium isn’t “bad” - it’s just less predictable for high-value crop production. Purified CalNit like the main component in our Part A fertilizer, gives you control, consistency, and the absolute best protein formation.

Most irrigation problems we troubleshoot trace back to one thing: pH management mistakes. The most common? Trusting an inline meter and ignoring what’s happening in the batch tank. When pH Up hasn’t finished reacting, the real pH continues to drift upward—pushing the solution past 6.2, triggering calcium-phosphate precipitation, and eventually clogging filters and emitters.In this episode, Matt and Tyler break down why inline readings mislead at high flow rates, why the “15–20 minute rule” still matters, and how a simple 5-gallon bucket test gives you the only trustworthy pH-Up dose for your recipe.If your system keeps forming white chalky buildup or you’re fighting mysterious clogs, this is your fix.

Why do some hydroponic grows see great yields in winter… then slow growth, yellowing, or strange pH problems in summer?
In this video, Front Row Ag’s Matt and Tyler share real cases from commercial facilities where:
Water temperature rose seasonally, dissolved oxygen crashed, and yields dropped.Root zones got too cold on concrete floors, bottlenecking growth even with perfect nutrients.Runoff pH looked wrong because irrigation shots were too large and too frequent, giving false readings.Growers overcorrected pH and wrecked consistency — when the real problem was irrigation strategy.👉 If your hydroponic plants are showing slow growth, stunted roots, low pH, or misleading runoff data, this episode will help you spot the hidden root zone issues that most growers miss.
