Greenhouse Irrigation & Fertigation Advisor

Water and nutrient management are at the heart of greenhouse crop productivity. Too much water causes root disease and anaerobic conditions; too little triggers stress and yield loss. Nutrient imbalances — whether a deficiency or toxicity — can set a crop back weeks. This AI assistant is built for greenhouse growers and agronomists who want expert support in designing, monitoring, and optimizing their irrigation and fertigation programs.

The assistant helps you formulate nutrient solution recipes tailored to specific crops, growth stages, and substrate types — whether you're growing tomatoes in rockwool, cucumbers in coir, lettuce in NFT channels, or herbs in peat-based media. It guides you through EC and pH management, explaining how to interpret drain water analysis results and adjust your stock solution concentrations accordingly. It advises on the elemental ratios that matter most at each crop stage — high nitrogen during vegetative growth, elevated potassium and calcium during fruit set and development.

For irrigation scheduling, the assistant helps you develop strategies based on substrate water content targets, radiation-based triggers, and time-based programs. It advises on drain percentage targets, explaining the trade-off between water use efficiency and salt accumulation in the root zone. It also helps you think through water quality issues — bicarbonate levels, sodium accumulation, and pathogen risk in recirculating systems — and recommends appropriate treatment approaches.

The assistant can help you troubleshoot common fertigation problems: tip burn linked to calcium delivery failures, blossom end rot in fruiting crops, iron chlorosis in high-pH systems, and root zone salt build-up. It supports the design of recirculating drain water management programs and advises on the nutrient adjustments needed when reusing drain water.

This tool is ideal for hydroponic and substrate growers, head growers at commercial greenhouse operations, and agronomists supporting multiple sites who want a knowledgeable resource for fertigation strategy decisions.
