Get the Best QuoteWhat Greenhouse Irrigation Includes
- Dripper systems. Drip lines with stakes or arrow drippers to each bag, pot or slab.
- Mixing and dosing. Fertigation units that mix nutrients to set EC and pH for every irrigation.
- Hydroponics. NFT channels, deep water culture or substrate systems with nutrient tanks.
- Recirculation. Collecting drain water, filtering or disinfecting it and reusing it.
- Misting and fogging. High-pressure nozzles for propagation, cooling and humidity control.
Who It Suits
Commercial tomato, cucumber, pepper, berry, herb and flower growers, propagation nurseries and seedling producers working in climate-controlled structures.
Because plants in substrate hold little water, these crops need short, frequent pulses, which makes accurate dosing and control essential.
System Options
- Open drain-to-waste. Simpler and cheaper. Drain water runs off, so more water and fertiliser is used.
- Closed recirculating. Reuses drainage. Saves inputs but needs disinfection and careful nutrient balance.
- NFT or water culture. Suits leafy greens and herbs. No substrate, but pumps must run reliably.
- Misting or fogging. Fogging gives finer droplets and less wetting. Match to propagation or cooling needs.
Irrigation interacts with climate. Heat, light and ventilation drive water use, so ask whether the controller can trigger on radiation or link to climate control.
How the Job Runs
- Site visit. The specialist checks the structure, crop layout, water source and water quality.
- Design. Dripper flow, pulse sizes, mixing tanks, filtration and drain handling are planned.
- Quote. Equipment, installation and commissioning are priced per house or per m².
- Installation. Headworks, distribution lines and drippers are fitted to the growing layout.
- Commissioning. Dripper output, EC and pH are checked and the controller is programmed.

Prices JUST UPDATED. Ballpark figures, rounded, excluding VAT unless stated. They are compiled from published South African cost estimates and typical supplier and contractor rates. They are not our prices or quotations, and no contractor is bound by them. Unless a row says otherwise they exclude the water source, power supply and earthworks, so confirm exactly what each quotation includes.

Get the Best QuoteWhat Affects the Price
- Area in m². Larger houses spread headworks cost over more area.
- Control level. A basic timer costs far less than automated EC/pH dosing.
- Recirculation. Drain collection, storage and disinfection add significant cost.
- Water quality. Borehole or dam water may need extra filtration or treatment.
- Misting pressure. High-pressure fogging pumps and nozzles cost more than low-pressure misting.
Maintenance
Calibrate EC and pH sensors regularly and clean filters often. Flush lines between crops and treat for biofilm and salt build-up.
Check dripper output and drain percentage, and descale mist nozzles that block from hard water.
Greenhouse Irrigation FAQs
Should I recirculate drain water?
It saves water and fertiliser but needs disinfection and closer nutrient management. Ask quoting specialists to price both options.
Can my existing structure take hydroponics?
Often yes, but floor levels, drainage and roof loading for hanging gutters must be checked during the site visit.
What water quality do I need?
Low salts and clean water matter most. A water test before design helps specialists size filtration and treatment correctly.
