Different plant species have evolved under different natural light conditions, and their photobiological responses to specific wavelengths vary significantly. While our standard full spectrum delivers excellent results across most commercial crops, optimizing the spectral recipe for your specific target plants can unlock substantial improvements.
**Tomatoes: High Red, Strategic Far-Red**
Tomatoes are high-light fruiting crops that respond strongly to red and far-red wavelengths. Our recommended tomato spectrum emphasizes 660nm deep red (30-35% of total PPF) for photosynthetic efficiency and fruit development, with 730nm far-red (8-12%) to promote flowering gene expression. Under this spectrum, commercial greenhouse tomato growers report 20-30% yield increases and 0.5-1.5°Brix sugar content improvements.
**Lettuce and Leafy Greens: Blue-Enhanced for Quality**
Lettuce requires moderate light intensity (PPFD 150-250 umol/m²/s) but shows strong morphological responses to blue light ratio. Our lettuce-optimized spectrum increases the blue proportion to 22-25%, producing compact, dense heads with short petioles — the preferred morphology for premium markets.
**Medicinal Plants: Full Spectrum Plus UV Enhancement**
Medicinal plants represent the most spectrally demanding commercial crop. Our standard full spectrum (3000K + 5000K + 660nm + 730nm) provides excellent baseline performance. Adding UVA at 15-25 umol/m²/s during the final 2-3 weeks of flowering increases total terpene content by 15-30%.
**Strawberries: Balanced Spectrum with UV for Quality**
Strawberry production requires a balanced spectrum that supports both vegetative growth and fruit quality. UV-A exposure during fruit development stages increases anthocyanin accumulation, elevates sugar content by 0.3-0.8°Brix, and improves firmness.
**Peppers and Cucumbers: Tomato-Analogous with Higher Intensity**
Both peppers and cucumbers share photobiological similarities with tomatoes — they are high-light fruiting crops that benefit from red-weighted spectra. We recommend the same basic recipe as tomatoes with intensity increased to 500-700 umol/m²/s for peppers and 400-600 umol/m²/s for cucumbers.
