Substrate slab drip systems (stone wool, coir)
What is a substrate slab drip systems (stone wool, coir)?
Substrate slab systems grow crops in slabs of stone wool or coir fed by drippers, with drain water measured to steer nutrition. They are the standard for high-wire tomatoes, cucumbers and peppers, but need careful start-up, drain management and a plan for used substrate.
Premium collection: Root-zone steering with measured drain for high-yield greenhouse vegetables and berries. Criteria met: Closed-loop control, Measured resource efficiency.

Advantages
- Precise root-zone water and nutrient steering
- Clean, uniform starting medium
- Proven in commercial greenhouses
Limitations and risks
- Drain water must be collected or treated
- Used slabs need disposal or recycling
- Coir quality varies with washing and buffering
Maintenance
- Measure drain EC and volume daily
- Check drippers for blockage
- Replace slabs on the planned cycle
Sustainability and compliance
Ask how drain water is reused and how used stone wool or coir is recycled.
Ask for batch EC, sodium and chloride results and, for coir, washing/buffering records.
Questions to ask in your RFQ
- What batch analysis comes with each delivery?
- Is coir washed and buffered?
- What recycling route exists for used slabs?
