Prevent Fertigation Clogs with Better Fertilizer Chemistry

Season 1 · Episode 30

Thursday, July 30, 2026 • Duration 01:34

Why is Front Row built as a 3-part fertilizer system?

It comes down to basic fertilizer chemistry.

In this clip, Bryan explains why calcium and phosphorus concentrates should always remain separate, why clogging is one of the most common issues new customers experience, and the difference between chemical and biological clogs.

He also explains how feed solution pH and EC affect the likelihood of calcium and phosphorus bonding together, increasing the risk of precipitation and clogged irrigation components.

Commercial Workflows and Irrigation with Drew Greco

Season 1 · Episode 29

Thursday, July 23, 2026 • Duration 31:34

Labor overhead, irrigation strategy, and equipment maintenance are critical variables that dictate commercial cannabis profitability. In this episode, experienced commercial cultivator Drew Greco breaks down the operational strategies that make large-scale facilities successful. Drew explains why implementing a strict preventative maintenance schedule is just as critical as managing a harvest calendar, and how correcting irrigation volume and reducing plant touches can drastically lower costs and improve plant health. The conversation also explores the transition to Front Row Ag detailing how a robust micronutrient profile drives distinct flower morphology and maximizes terpene production compared to competitor lines. In this episode:

Building preventative maintenance schedules for facility equipment.
Reducing labor costs by limiting plant touches and avoiding unnecessary topping.
Correcting common commercial irrigation mistakes like overwatering.
How the micronutrients in Front Row Ag fertilizer influence cannabis flower expression and flavor.
Utilizing water analysis to identify root zone pathogens like Fusarium.

Why the Same Program Succeeds in One Facility and Fails in Another

Season 1 · Episode 27

Wednesday, June 24, 2026 • Duration 17:35

Most fertilizer companies stop at product delivery. At Front Row Ag, that's where the work begins.

In this episode, we discuss how commercial customer onboarding helps identify operational challenges before they become expensive problems. From water chemistry and sanitation to irrigation infrastructure and facility workflows, our team works to establish a clean baseline before implementing a nutrient program.

You'll learn why water testing is one of the first steps in every onboarding process, how hidden sanitation issues can impact facility performance, and why successful nutrient programs must be customized to each operation.

We also discuss preventative maintenance, common mistakes that lead to recurring production issues, and how ongoing education and technical support help commercial facilities achieve more consistent results over time.

PSA: How Sulfuric Acid Supply Impacts Your Fertilizer Program

Season 1 · Episode 26

Monday, June 22, 2026 • Duration 10:59

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 production
How global supply chain disruptions can affect fertilizer manufacturing
Why some growers are seeing more residue and precipitation in stock tanks
Which fertilizer ingredients are most vulnerable to upstream sourcing changes
What growers should watch for when evaluating fertilizer quality
How quality assurance and analytical testing help maintain consistency

Why Some LED Grow Upgrades FAIL the Math

Season 1 · Episode 25

Wednesday, June 3, 2026 • Duration 13:05

Two facilities. Same canopy size. Same yield target. Completely different electrical bills.

In this episode, we break down the lighting math most growers skip:

watts per square foot
PPFD and uniformity
fixture spacing
mounting height
PPE efficiency
under canopy lighting
why some facilities massively overspend on LEDs

This conversation explores how modern lighting design affects yield, operational costs, and long-term profitability in commercial cultivation environments.

Whether you're planning a retrofit, building a new room, or trying to lower COGS, understanding the math behind your lighting matters more than marketing brochures.

SIU Researcher Dr. Jose Leme on Trichomes, Water Stress, and Biostimulants in Cultivation

Season 1 · Episode 24

Thursday, April 30, 2026 • Duration 49:38

What happens when you stress plants on purpose?

In this video, we break down university research from Dr. Jose Leme’s lab on plant stress, trichomes, water deficit, and biostimulants.

Topics covered:

Stress signals vs real stress
Trichome development and plant defense
Water deficit strategies (dry back vs dry out)
Biostimulants like seaweed, humic acid, chitosan, and silica
How timing, environment, and genetics affect outcomes

Some of the results challenge common assumptions.

If you're interested in plant science, controlled environment agriculture, or optimizing plant performance, this is worth understanding.

Hiring a Lead Cultivator: What To Look For

Season 1 · Episode 23

Thursday, April 30, 2026 • Duration 05:14

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 risky
What actually matters in a lead role
How to avoid costly hiring mistakes

Light Interruption Can Cause Herms (+How to Stop It)

Season 1 · Episode 22

Thursday, April 30, 2026 • Duration 06:36

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 over
Where light leaks actually come from (doors, ductwork, equipment)
How even small LEDs can impact sensitive varieties
The difference between resilient vs. finicky genetics
Why green aisle lighting is a safer—but not perfect—solution

This is practical, field-tested insight for operators who want consistency, not surprises.
