After analyzing systems, nutrients, light, automation and artificial intelligence, we come to the most advanced point in professional indoor growing: scientifically measuring what really works.
This is where A/B testing applied to hydroponics comes in.
Doing A/B testing means comparing two controlled variants of the same growing cycle, changing only one variable at a time, to see which choice generates better results in terms of yield, quality or stability.
An A/B test involves:
Everything else must remain absolutely the same:
Only then are the data collected clean, comparable and reliable.
The most useful A/B tests in hydroponics involve:
Testing multiple variables together renders the data inert and unusable.
A good A/B test must:
The most commonly used metrics are:
Poorly done A/B testing is worse than no testing: it leads to bad decisions.
The true value of A/B tests emerges when:
This is where hydroponics evolves from "cultivation" to a data-driven engineered system.
With this article we close our journey:
From the basics of hydroponics to advanced experimental testing, via vertical farming, automation and AI.
If you have followed this series, you are now no longer simply farming:
you're designing controlled, measurable, and scalable production systems.
