Tomato Greenhouse

Tomato rewards stability more than extremes. The climate package must hold night temperature and humidity within a narrow band while maintaining active air movement through a dense canopy, because most tomato disease pressure is a humidity management failure rather than a hygiene failure.

• Day 21 – 24 °C, night 16 – 18 °C, tightly controlled
• Humidity deficit managed with dual energy screens
• CO₂ dosing to 800 – 1,000 ppm during light hours
• Active dehumidification and vertical air circulation
• Screen strategy tuned to limit head condensation

High-wire tomato is grown on inert substrate with frequent, small irrigation events. Control is based on drain percentage and EC feedback rather than a fixed clock, so root zone conditions steer the plant between vegetative and generative growth.

• Stone wool or coco substrate with per-slab drain monitoring
• 6 – 12 irrigation cycles daily, driven by radiation sum
• Feed EC 2.5 – 4.0 mS/cm steered by crop stage
• 25 – 35 % drain with UV-treated recirculation
• Separate A/B stock tanks with acid dosing for pH control

Yield per square metre, energy cost per kilogram and labour hours per kilogram determine margin. Technology decisions should be evaluated against those three metrics rather than against capital cost alone.

We model the production plan with your target market and variety, specify the greenhouse and climate package, tender to qualified suppliers and coordinate construction and crop start-up.

• Variety and market programme review
• Light, climate and CO₂ strategy
• Substrate and fertigation design
• Labour planning and internal logistics
