Which structure should I use when growing tomatoes?

There are three common greenhouse structures: glasshouses, poly houses, and net houses. All three are suitable for growing tomatoes. The questions you should ask are: what are the local environmental conditions? And, how much do you want / can you invest?Glasshouse structures are suitable for commercial production of tomatoes in mild to cold climates (heavy snow load) and require high investments. Poly houses are suitable for diverse climatic conditions, and net-houses will be more suitable for dry or hotter climate conditions (non-rainy climates).

What is the average yield for different greenhouse structures and technologies, assuming climate conditions are optimal?

Net-houses: 10-15 kg/m2 (short cycle crop)Low-tech / simple poly houses: 25-30 kg/m2 per year (1 long cycle of 10-11 months, or 2 short cycles of ~5 months each)Hi-tech greenhouses with climate control system: 40-70 kg/m2 (1 long cycle of 10 months)

What is the growth cycle of greenhouse tomatoes?

Short cycle: 140 - 150 days from planting to harvestLong cycle: 10 - 11 growing months, including 9 months of harvesting

How do the EC and pH affect my greenhouse tomatoes?

Ensuring the right EC, pH, and nutrient levels in the root zone is critical for fast-growing and high-yielding crops. This is especially true when growing in soilless media, since the growing medium has low buffer capabilities and demands a fast and precise reaction. You need a system that can react quickly to any change, be it crop stage or climate. This can mean the difference between winning and losing. Precision drip systems are based on non-drainage drippers, designed for pulse irrigation and special dosing systems that allow you to keep all parameters exactly where you need them, and react to changes on demand.

What are the benefits of Compensated Non-Leakage (CNL) drippers?

Irrigation of soilless media is characterised by short irrigation pulses (minutes). With CNL drippers, you increase Fertigation™ uniformity by eliminating the refilling time of the system and preventing system drainage. This means that all the drippers start and stop to drip at exactly the same time every irrigation cycle, guaranteeing equal quantities of water and fertilisers to all plants.

MEET DEMAND WITH BETTER TOMATOES

Growing greenhouse tomatoes carries big investments. It’s a game of driving high, quality yields from every square metre to meet consumer demand and maximise your ROI. For optimal growing conditions, you need the right structure, agro-technical solutions, tools and agronomic know-how.
