Short answer: A greenhouse fertigation room should provide safe chemical storage, clean water and drain separation, tanks, filters, dosing equipment, pumps, controls, ventilation, lighting, containment, maintenance access and future expansion. Layout should follow the process flow from raw water to irrigation zones and keep electrical equipment protected from leaks and chemicals.
Create a simple flow diagram showing water source, raw-water tank, treatment, filtration, fertilizer stock tanks, acid or alkali where used, dosing, mixing, irrigation pumps, zone valves, greenhouse distribution, drainage and recirculation. Identify which equipment is supplied with the greenhouse and which comes from local civil, electrical or water contractors.
| Equipment group | Information needed |
|---|---|
| Tanks | Purpose, working volume, material, access, drain, level sensing and mixing. |
| Filters and treatment | Flow, pressure, filtration level, backwash or flushing and waste route. |
| Dosing | Number of channels, injection method, stock concentration, calibration and compatibility. |
| Pumps and valves | Duty point, standby philosophy, materials, controls and maintenance clearance. |
| Controls and sensors | EC, pH, flow, pressure, levels, alarms, data and manual operation. |
Locate electrical panels, drives and communication equipment away from splash and corrosive vapor. Chemical storage should follow product labels, compatibility rules and local safety requirements. Provide secondary containment, clear labels, safe transfer methods and emergency procedures appropriate to the materials used.
Leave working space around filters, pumps, injectors, membranes, tanks and panels. Components that require frequent cleaning or calibration should not be blocked by pipes. Provide lifting and replacement routes for heavy equipment. Doors and aisles should accommodate the largest component and safe material handling.
Use a durable, cleanable floor suitable for the project chemicals and water. Define how normal wash water, filter backwash, treatment reject, nutrient spills and concentrated chemicals are collected or managed. Do not discharge them to stormwater without approved review. Protect the room from external flooding.
Provide enough ventilation and lighting for inspection, mixing, calibration and maintenance. Consider heat generated by pumps and electrical equipment. Follow local safety requirements for chemical handling, eyewash or other emergency facilities where applicable. Keep food, personal items and unauthorized people out of chemical areas.
Use a laboratory water analysis to select treatment and fertilizer strategy. Check compatibility among water, fertilizers, acids, disinfectants, tanks, seals, pumps and piping. A component suitable for clean water may not suit concentrated stock solution or treatment chemicals.
Define alarms for low tank level, high or low pressure, dosing deviation, filter condition, pump fault, high EC or pH limits and communication loss as appropriate. Establish manual watering or backup operation for critical crops. Test sensor calibration, interlocks and alarm notification during commissioning.

They require appropriate separation and protection from splash, leaks and corrosive conditions according to the project design.
No. Automation level depends on crop, water, scale, operator skill and risk, but measurement and calibration remain necessary.
