Overcoming challenges in pepper production
Growing peppers under traditional LED systems often presents growers with significant challenges: - Low transpiration rates, impacting nutrient uptake. - Varied growth rates and internode lengths across different varieties, complicating uniform production.
Sollum’s dynamic LED lighting solution addresses these issues by tailoring light intensity and spectrum to the specific needs of each variety, ensuring optimal growth conditions throughout the production cycle.
Objective: enhance pepper production and Light Use Efficiency (LUE) under dynamic LED lighting.
Setup: - Planting date: early October. - PPFD levels: 250-270 μmol/m2/s. - Lighting strategy: 16-hour day length using adaptive dynamic lighting. - Trial period: Week 40 to Week 22 (end of May). However, the trial lasted until the end of August.
Dynamic adjustments: focused on fine-tuning far-red strategies and spectrum adjustments to optimize internode length, fruit set, and plant development.
Key results
Yield and quality improvements: - Total yield: Increased from 45.67 kg/m2 (2020-2021 trial) to 46.71 kg/m2 in the 2023-2024 trial. - Class I peppers: Improved from 40.74 kg/m2 to 41.75 kg/m2, reflecting higher quality. - Class II peppers: Reduced from 2.36 kg/m2 to 1.06 kg/m2, minimizing lower-grade produce.

Efficiency gains
- Light Use Efficiency (LUE): Achieved a remarkable 6.2 grams/mol, optimizing light-to-biomass conversion.
- Fruit stability: Maintained consistent fruit weights of 190-220 grams, with a rapid outgrowth period of 44 days from fruit set to harvest.
- Tailored spectral recipes: Enabled precise adjustments for variety-specific needs, ensuring consistent quality across all cultivars.
