First NFT: The First Pour of Hydroponics

+

2014. A shipping container, a dream, and a lot of mistakes.

+
+ +
+

The Beginning

+

It started with a single idea: grow food without soil. In 2014, I set up my first Nutrient Film Technique (NFT) system in a repurposed shipping container in the heart of Salt Lake City. The goal? To create a self-sustaining micro-farm that could thrive in the harshest conditions.

+

But it wasn’t easy. The first few weeks were a disaster. pH levels swung wildly. The water was too hot in the summer, too cold in the winter. The lettuce grew moldy, the tomatoes wilted, and the basil turned to mush.

+

But every mistake taught me something. I learned how to balance light, water, and nutrients in a closed loop. I learned how to automate the watering schedule with a simple Arduino board. And most importantly, I learned that every failure is just data for the next harvest.

+
+ +
+

The Science of NFT

+

Nutrient Film Technique (NFT) is a method within hydroponics where plants are grown in a thin film of nutrient-rich water. The roots hang in a shallow channel, and the water flows continuously over them, delivering oxygen and nutrients.

+

Here’s the secret sauce:

+ +

It’s a delicate balance. Too much light and the plants burn. Too little and they stretch for the sun. Too much water and the roots drown. Too little and they starve.

+
+ +
+

The Code Behind the Green

+

Automation is the key to success. Here’s the code I wrote to control the watering schedule:

+
+// Arduino NFT Controller +#include <Wire.h> +#include <LiquidCrystal_I2C.h> + +LiquidCrystal_I2C lcd(0x27, 16, 2); +int pumpPin = 9; +int sensorPin = A0; + +void setup() { + pinMode(pumpPin, OUTPUT); + lcd.begin(16, 2); + lcd.print("NFT System"); +} + +void loop() { + int moisture = analogRead(sensorPin); + if (moisture < 300) { + digitalWrite(pumpPin, HIGH); + delay(10000); // 10 seconds of water + digitalWrite(pumpPin, LOW); + } + lcd.setCursor(0, 0); + lcd.print("Moisture: "); + lcd.print(moisture); + delay(60000); // Check every minute +} +
+

This simple script keeps the plants happy, no matter what. It’s the perfect example of how technology can help us grow food in the most unlikely places.

+
+ +
+

The Gallery of Mistakes

+

Here’s a look at the highs and lows of my first NFT system. From the first sprout to the final harvest, every step was a lesson.

+
+ First sprout + Moldy lettuce + Perfect tomato + Final harvest +
+
+ +
+

What’s Next?

+

This is just the beginning. I’m now designing precision irrigation networks for greenhouses all over the world. Every system I build is a tribute to that first failed NFT setup.

What I Do

+

I design precision irrigation networks that merge sustainability with visual appeal. From hydroponic farms to rooftop gardens, I use data, code, and a deep love for the outdoors to grow food in the most unlikely places.

When I'm not in the greenhouse, I'm brewing beer, playing guitar, or building something new in my workshop.

Precision pump scheduling for closed-loop hydroponics & field crops

+ ← Return to Workshop + Q5187947 | FAO-56 +
+ +
+
+

THE THEORY

+

In precision irrigation, the pump is not a switch. It is a metronome. Every cycle must deliver exactly the volume lost to evapotranspiration plus the maintenance reserve for root zone saturation.

+ +
+ V_required = (ET₀ × Kc × A_root) − SM_deficit

+ T_pump = V_required ÷ Q_pump × 60 +
+ +

Where:

+
    +
  • ET₀ = Reference evapotranspiration (mm/day, from Penman-Monteith)
    • +
  • Kc = Crop coefficient (dimensionless, stage-dependent)
    • +
  • A_root = Root zone area (m²)
    • +
  • SM_deficit = Current soil moisture deficit (L)
    • +
  • Q_pump = Pump flow rate (L/min)
    • +
+ +
+ Grounded in Q5187947 (crop coefficient) • FAO Irrigation Paper No. 56 • Allen et al. 1998 +
+ +
+

Field Note: In my Wasatch trials, I discovered that lettuce at mid-canopy (Kc ≈ 1.15) demands 4.2 mm/day in July. A 12 L/min pump servicing 50 m² must run exactly 11 minutes per 24 hours. Anything less stresses the roots. Anything more leaches nutrients.

The Smoke Index

+
Converting wildfire haze into photosynthetic suppression rates for Utah's fields.
+
+ +
+
+

Context: When the Sky Turns Purple

+

July 18, 2026: Salem reports haze hanging around. Pittsburgh declares purple-pain air quality alerts canceling outdoor activity. British Columbia's Big Bar Lake wildfire burns. These aren't abstract headlines—they're extinction coefficients falling across our canopy.

+ + NASA ISS photograph of wildfire smoke plume over forest landscape + ISS070-E-008930: Wildfire smoke column observed from orbit. NASA Public Domain. + +

When smoke blankets the Wasatch Front, two mechanisms kill yield:

+
    +
  1. Light Extinction: Particulate matter scatters PAR (400–700nm). Net radiation drops non-linearly with optical depth.
    2. +
  2. Stomatal Closure: Ozone and ultrafine particles trigger guard-cell collapse. CO₂ intake halts even if photons remain.
    3. +
+

This tool maps AQI PM2.5 and visual range to expected Gross Photosynthesis Suppression (%) for Utah's five major crops.

Model Parameters

The suppression rate derives from three coupled equations:

+
    +
  1. Optical Depth (τ): τ = k × (PM2.5 / 10)^(1.3)
    2. +
  2. PAR Transmission: T_PAR = exp(-α × τ)

  3. Net Suppression: S_net = (1 - T_PAR^β) + γ × f_ozone(PM2.5)

Where Precision Meets Surprise

+

In a world obsessed with perfection, I've found my greatest joy in the beautiful mistake. As an agricultural engineer and homebrewer, I've learned that the most delicious crops and the most flavorful brews come from embracing the unexpected. Welcome to The Controlled Glitch—where we celebrate the art of intentional imperfection.

+
+ +
+

The Science of Serendipity

+

Controlled Environment Agriculture (CEA) is all about precision. But what happens when you intentionally introduce a "glitch" into the system? By manipulating light, temperature, and humidity, we can create micro-climates that produce unique flavors and textures in our crops.

+
+ "The crack in the plan is where the real art bleeds in. Every mistake is a lesson, and every lesson is a new opportunity to create something beautiful." +
+

From hydroponic lettuce with a hint of basil flavor to tomatoes that taste like they're from a sunny Mediterranean greenhouse, the possibilities are endless.

+
+ +
+

Brewing with a Twist

+

Just like in the garden, brewing is a science. But the best brews come from a little bit of chaos. Whether it's a wild yeast infection that turns your IPA into a sour masterpiece, or a temperature fluctuation that gives your stout a unique depth of flavor, every "mistake" is a chance to learn something new.

+

From the perfect pour to the accidental masterpiece, brewing is all about finding the balance between control and creativity.
