FRUIT VEGETABLE
Tomato under protection
The crop that pays for high-tech glass: long cycles, high value per square metre, and a climate the house must hold for nine months.
Truss types need structural support and regular pruning labour; cherry types need tighter humidity control to avoid splitting.
In hot climates the limiting factor is night temperature, not day temperature: if nights stay above 22 °C, fruit set drops and quality falls. Cooling strategy decides the season.
Climate range and crop notes
| Day temperature | 19–26 °C |
| Night temperature | 14–18 °C |
| Humidity | 65–80 % RH, VPD 0.8–1.5 kPa |
| Light | 20–30 mol/m²/day for set; supplementary light in low-light winters |
| EC / pH | 2.4–3.5 mS/cm, pH 5.5–6.0 in substrate |
| Cycle | Annual or long-cycle, 9–11 months |
General horticultural ranges for a well-managed crop; local variety, light and market specification move these values. Not a yield guarantee.
First-season mistakes that cost the most
- Sizing cooling on average summer temperature instead of the design day.
- Running high EC in strong light without checking drainage EC.
- Buying the house before deciding the substrate and irrigation layout.
