Temperature and humidity values are indicative design targets. Actual performance depends on ambient conditions, crop load, water quality, electricity, equipment sizing, maintenance and correct operation. The signed IGPL proposal defines the final specification.
A crop system—not just growing channels.
The right configuration follows the crop, source-water analysis, climate, production target and operator capability. These indicative parameters become project-specific during engineering.
Crop-stage recipes guide nutrient availability and solution strength.
NFT, raft, Dutch bucket or substrate systems are selected for the application.
Monitoring, dosing, alarms and records reduce avoidable operator error.
Crop system, water layer, controls and training are coordinated together.
| Design area | Indicative IGPL specification | What this means for the client |
|---|---|---|
| 01 · Crop system and project fit | ||
| Growing-system options | NFT channels, deep-water or raft systems, Dutch buckets, substrate grow bags, troughs or crop-specific combinations | The hardware follows the crop and operating plan instead of forcing every crop into one method. |
| Typical crop pathways | Leafy greens and herbs for NFT or raft systems; tomato, cucumber, capsicum, strawberry and similar fruiting crops for engineered substrate systems | Crop architecture, root volume, support, harvest workflow and market objective are considered together. |
| Greenhouse integration | Crop layout coordinated with structure, climate control, access, trellising, drainage, electrical and hygiene zones | Reduces conflicts between growing equipment and the greenhouse operating environment. |
| Production zoning | Independent irrigation or nutrient zones where crop stage, variety or hydraulic demand differs | Allows more precise scheduling and avoids treating unlike crop blocks as one zone. |
| 02 · Water, nutrition and root-zone management | ||
| Source-water assessment | Laboratory review of pH, EC, alkalinity and relevant dissolved salts before nutrient-system design | Identifies water-treatment and recipe risks before equipment is sized. |
| Nutrient-solution pH | Typically 5.0–6.0 at solution preparation; the final target is crop- and system-specific | Keeps nutrient availability within a controllable range without presenting one setpoint as universal. |
| Electrical conductivity | Typically 1.5–3.0 dS/m as a broad commercial planning range, with crop-stage recipes outside or within that range as required | Solution strength is managed by crop response—not by a single fixed EC for the whole farm. |
| Storage and mixing | Covered nutrient tanks, stock-solution tanks, agitation or circulation, level control and safe chemical handling layout | Supports repeatable mixing while limiting light entry, contamination and dosing mistakes. |
| Filtration and treatment | Media, screen or disc filtration with disinfection or source-water treatment where analysis and recirculation strategy require it | Protects emitters and root zones; final filtration grade follows the selected system and water source. |
| Delivery and drainage | Hydraulically sized pumps, mains, valves, laterals, return lines and measurable drainage or recirculation | Helps deliver solution consistently and makes runoff or return flow visible to the operator. |
| 03 · Monitoring, automation and risk control | ||
| Core monitoring | pH, EC, nutrient-solution temperature, tank level, flow and pressure; dissolved-oxygen monitoring where relevant | Turns critical root-zone conditions into measurable operating information. |
| Dosing and scheduling | Automated nutrient and pH dosing with timed or sensor-informed irrigation recipes for commercial projects | Reduces repetitive manual adjustment and helps prevent sudden nutrient changes. |
| Alarms and records | Configurable high/low alerts, equipment-status monitoring and data logging according to the control scope | Helps the team respond sooner and review operating trends instead of relying on memory. |
| Resilience provisions | Duty/standby strategy, backup power assessment, bypasses and emergency operating procedures for critical pumps and controls | Plans for failure modes that can affect roots quickly in water-based production. |
| Hygiene and training | Cleanable layout, crop-zone SOPs, sanitation checkpoints, commissioning and operator training | Recognises that disciplined daily management is part of system performance. |
| Delivery and installation | Turnkey coordination by the IGPL engineering team across India, subject to the signed scope | Single-point coordination for crop system, water, controls, commissioning and training. |
Indicative planning specification informed by established hydroponic guidance. Final system type, nutrient recipe, pH/EC targets, flow rates, tank capacity, treatment, automation and crop claims depend on laboratory water analysis, crop protocol, climate and site-specific engineering. The signed IGPL proposal is the controlling specification.
Where this system earns its place.
