Coach Monitor

Coach Control that explains what to fix first

The coach checks the tanks, finds the weakest point and gives the next practical action first. A compact monitor preview then proves where the recommendation came from.

Coach Control · Hybrid

The coach gives the answer, then shows the proof

The first thing a visitor sees is the practical recommendation. The monitor proof sits next to it, so the message feels simple without looking made up.

Tank 2 needs attention

EC is too high at 2.45 mS/cm for lettuce.

Why it matters

Strong solution can stress roots and make water uptake harder, especially during warm periods.

Recommended action

Dilute with clean water. Mix well, wait a few minutes and measure again before adding fertiliser.

Start with Tank 2. Fix EC first, then measure again.

Monitor proof

How the coach knows what to fix first

A compact view of the real Coach Control: tank ranking, the weakest tank and the reason behind the recommendation.

Coach Health Check Tank 2 · Lettuce

Weakest tank: EC is 2.45 mS/cm. Target for lettuce is 1.2-2.0 mS/cm.

Tank 1 · RocketpH outside target 88/100

Tank 2 · LettuceEC needs attention 76/100

Tank 3 · Mustard spinachLow flow risk 88/100

Coach action

Dilute Tank 2 with clean water, then retest EC before doing anything else.

The platform

Three coaches. Use one, or connect them.

Each coach can stand on its own. Choose the tool that fits your classroom, production system or setup need. When connected, the same tank problem can move from diagnosis to understanding to action.

Coach Monitor

Best for daily control

For teachers and growers who need to enter readings, rank tanks and get a practical recommendation.

Coach Learner

Best for classrooms

For learners who need to understand readings, plant response and system problems in simple language.

The plant may wilt or grow slower.

Coach Grow Guide

Best for setup and fixes

For users who need a practical reference for NFT setup, crops, symptoms and correction steps.

Works on its own Dilute with clean water.
Mix well, wait a few minutes and measure EC again.

When connected, one problem can travel through the whole learning loop.

Monitor diagnoses the tank, Learner explains what the plant may show, and Grow Guide gives the correction step.

Learner Monitor Preview

The same problem, explained visually

The coach can flag a high EC problem for the teacher, then the learner view turns that same problem into a simple plant-response explanation with a visual symptom example.

Tank 2 · EC Read-only learner view

EC is too high

The nutrient solution is too strong for lettuce. Dilute with clean water, mix well and measure EC again before adding fertiliser.

What learners will see

When EC is too high, the plant may look wilted or grow slower because the roots struggle to take up water from the strong solution.

Complete Grow Guide

From empty pipes to confident daily growing

The Grow Guide is the practical manual behind the system: setup, seedlings, crops, water readings, daily routines, symptoms, corrections and harvest decisions.

You can use it without the monitor, but it becomes even more powerful when the monitor points you to the right section.

For schools

Teach from the actual NFT system

Learners follow tank readings, flow, EC, pH and plant response from one real hydroponic system instead of a generic worksheet.

For growers

Catch root and flow problems earlier

Use the coach logic to connect low flow, water temperature, ORP and root health before one weak tank becomes a crop loss.

Now accepting practical pilot feedback

GroeiWys is being tested in a real school NFT environment before broader rollout to more schools and growers.

1. Test at Trio

Use the working NFT A-frame with real learners and teachers to collect practical feedback.

2. Add pilot partners

Work with a small number of schools and growers who can give useful, practical feedback.

3. Prepare for wider access

Use pilot feedback to strengthen accounts, access control and the sales process.
