Architecture first
Kratky is not NFT. Dutch buckets are not a windowsill jar. Match the crop to the plumbing.
Commercial hydroponic crop production
Precision Roots
The Horticultural Hydroponics Protocol
Soil-free, high-yield farming. From a BSc in horticulture and years of advanced hydroponics — systems, solution, climate and crop. Built for harvests, not hobby kits.

The problem
Most hydroponic teaching is a shopping list with a YouTube accent.
Buy this light. Buy that pump. Watch a plant die and guess. A commercial house does not guess. It runs a protocol: numbers you can write down, systems matched to crops, and a dump schedule that is not superstition.
Two meters
EC and pH. Millisiemens, not a mystery PPM scale. Mix A then B. Log the tank.
Climate as a tool
PPFD, DLI, root temperature. Warm water is a pathogen. Still air is a disease.
Instructor
BSc Horticulture
Advanced hydroponics
Degree-trained in horticulture, then years of advanced hydroponics as production. Source water, ion ratios, VPD, the pathogens that actually kill a tank — the knowledge between the BSc and a working bench.
YouTube sells hardware. A degree teaches botany. This course is the missing piece: a working method you can run on Monday morning with a meter and a notebook.
Curriculum
7 modules. The whole path.
- 01
Foundations
Why soil-free works, and how a plant actually eats.
- 02
Systems
Kratky to Dutch bucket — pick the architecture that matches the crop.
- 03
The solution
EC, pH, mixing, and the reservoir as a living instrument.
- 04
Climate
Light, vapour pressure and air — the environment around the leaf.
- 05
Crops
Recipes for greens, herbs and fruit — numbers you can run tomorrow.
- 06
In production
Disorders, pests, harvest, and the path from bench to market.
- 07
Advanced bench
Source water, ion antagonism, VPD steering, and the biology of a dirty tank.
Instruments
Four tools you will actually use.
A two-part mixer, a DLI calculator, a system picker, and a leaf diagnostic. They sit next to the lessons, not in a bonus graveyard.
Who it’s for
Built for a first serious bench.
- Spare-room or greenhouse growers who want market-grade greens.
- People who will keep a notebook and a meter, not a shopping cart.
- A first fruiting vine — tomato or cucumber — once lettuce is boring.
Not for anyone expecting a fully automated farm by Sunday, or a substitute for a horticulture degree.
Questions
FAQ
Who teaches this?+−
A horticulturist with a BSc and advanced hydroponics practice. The protocol is what sits between the degree and a working production bench.
I’m a beginner. Is this too commercial?+−
No. You start with a jar (Kratky) or a single DWC bucket. The commercial numbers are there so you don’t outgrow a hobby kit in a month.
Do I need a greenhouse?+−
No. A spare room, a tent, or a bright windowsill will run leafy greens. Fruiting crops want more light and a Dutch bucket.
Why not just watch YouTube?+−
YouTube sells hardware. This is a protocol: what to measure, what the number means, and when to dump the tank.
How long do I keep access?+−
As long as this device keeps the enrolment. One payment, no monthly fee.
