From the people growing
Real food. Real homes. Real change.
"I'd honestly killed every plant I'd ever owned, so I almost didn't buy. Three weeks into Foundations I was eating lettuce I grew myself. It finally clicked โ I get it now, and I can't stop growing."
Hydroponic Foundations
"We're on the third floor with no yard, and I just wanted my kids eating real food. We started with one jar on the windowsill and now we grow greens year-round. My five-year-old asks to 'check the garden' every single morning."
School of Hydroponics
"My Tower Garden sat half-empty for a year because I didn't really know what I was doing. This course fixed that in a weekend. Every port is full now and we haven't bought lettuce at the store in months."
Master Your Tower Garden
"I bought the whole School and it paid for itself fast. The indoor course alone changed how I run my grow room โ I'm harvesting something every week now, in the middle of winter. Worth every penny and then some."

My #1 recommended system
The Tower Garden is the best pre-fab hydroponic system on the market โ hands down.
I've built and broken every kind of system over fifteen years. When someone wants one that just works, this is the only one I point them to.
- Food-grade, UV-stabilized materials. Built to sit in full sun for years without breaking down โ and without leaching into your food.
- Aeroponic by design. Roots get oxygen and nutrient mist for faster, healthier growth than soil or basic water culture.
- Grows up, not out. 20+ plants in about three square feet โ perfect for a patio, balcony, or greenhouse.
A word of caution: a flood of cheap hydroponic towers are being mass-printed and sold for next to nothing. Many use low-grade plastics that can break down in sunlight and leach into the water your food drinks. With something feeding your family, materials are not the place to save a few dollars.

The fuel your plants drink
What are hydroponic nutrients, really?
In soil, plants spend energy hunting for minerals through dirt. In hydroponics, you hand those minerals straight to the roots in perfectly balanced water โ which is exactly why hydroponic plants grow faster and stronger.
1
What they are
The same essential minerals plants pull from healthy soil โ nitrogen, phosphorus, potassium, calcium, magnesium and trace elements โ in a form roots can drink directly.
2
Where they come from
Refined mineral salts, precisely measured and blended so every feeding is consistent โ no guessing whether your soil "has enough."
3
How they work
Dissolved in water, the minerals become ions roots absorb instantly. Less energy spent searching, more energy spent growing.
My preferred nutrients
General Hydroponics
After fifteen years and countless brands, General Hydroponics is what I keep coming back to โ for one reason: consistency. Every bottle performs the same, every time, so your grows stay predictable instead of becoming science experiments.
Their commitment to quality and reliable formulation is why it's the nutrient line I trust to feed the food my own family eats.

Meet Chad
Hey, I'm Chad โ and I've spent fifteen years chasing the perfect grow.
I didn't grow up a gardener. I got hooked on one stubborn idea: that you can grow real, beautiful food almost anywhere, with little more than water. Then I spent fifteen years proving it to myself the hard way โ fogponics, high-pressure aeroponics, Tower Gardens, deep water culture, Kratky. If there's a way to grow without soil, I've built it, flooded a room with it, and learned what actually holds up.
These days I've traded complicated for simple. My main grow is eight Tower Gardens in a greenhouse here in Hawaii โ and it's not for show. It's the lettuce, herbs, and greens my wife and our three kids actually eat. Honestly, some of my favorite mornings are out there with the little ones, picking breakfast straight off the towers.
I still keep an indoor grow room for the nerdy stuff โ running experiments, dialing in single crops, and growing 18+ plants โ so everything I teach gets tested before it ever reaches you. But the part that still gets me? The messages. Students sending photos of their first harvest. Teachers telling me a classroom garden changed how their kids think about food. That's the whole reason Humble Growth exists.

Before you start
Questions, answered.
I've never grown anything. Is this for me?
Especially for you. Hydroponic Foundations assumes zero experience and walks you from "what is this" to your first living plant. Most students get something growing within their first week.
Do I need expensive equipment to begin?
No. The Kratky method needs little more than a jar, a net cup, and nutrients. The courses show you how to start cheap and only upgrade once you know what you actually need.
What's included in the School of Hydroponics?
All four courses โ Hydroponic Foundations, Master Indoor Hydroponics, Master Your Tower Garden, and The One Pound Plant (18+) โ plus all four quick-start guides. $796 of material for $399 — about 50% off — plus a private community of growers worldwide, lifetime access, and every future release included free.
I think I'm ready to buy a Tower Garden — anything I should know?
It's the one pre-fab system I recommend without hesitation. If you're just getting started, the Tower Garden FLEX is the best place to begin. And if you're after a great deal — or you want a full garden that can actually feed your family — the Tower Garden FAMILY is my pick. You can explore every model here → Use my code HUMBLE100 for $100 off, and when you buy through my link I'll add the Master Your Tower Garden course free so you grow successfully from day one. Already own one? That course is your perfect next step.
How long do I have access?
Forever. Every course and guide is lifetime access, self-paced, and yours to revisit whenever a new grow raises a new question.
