Floriculture For Greenhouse
Existing research revealed part of the mysterious how different spectral and intensity combinations from blue (400-500 nm), green (500-600 nm), red (600-700), far-red (700-800 nm), and white LEDs interact to regulate photosynthesis, plant growth, and flowering responses on a broad range of floriculture crops.The floriculture industry encompasses a wide variety of planting styles from bedding, to potted and cut flowers. Lighting needs varywidelybased on species and production styles, however light remains an integral growth variable in production.Low light conditions result in poor quality plants that show an increase in blindness, stretching and have smaller flowers with thinner stems. If plants are grown at excessively high light levels, leaf orientation will change to avoid the light and the plants may also develop “sunburn”.
Grow lighting for ornamental generally accomplishes one of two purposes:
(1) Increase growth rates and quality, especially rooting and/or cut flower production with high intensity lighting.
(2) Simulate long days to control the timing of flowering for day length sensitive crops with low intensity photoperiodic lighting.
Grow Lights Recommended:
For high intensity, growth rate and quality enhancing lighting, generally target around 30-60 µmol*m-2*s-1, or about 40-110 sq ft of coverage per GB240 Broad Grow Spectrum Light fixture(ideally 5-7 ft or 150cm-210cm fixture heights from canopy). Cut flowers may use up to double this intensity, and lower intensities can be used for lesser but lower cost improvements.
For low intensity photoperiodic lighting, the most common solution is SRY60SW or SRY60FX on 50’ X50’ centers approx. 10' above the crop with 240LX (or 4.3µmol*m-2*s-1) or 17’ above the crop with 86 LX(1.54µmol*m-2*s-1).

The floriculture industry encompasses a wide variety of planting styles from bedding, to potted and cut flowers, so unknowing the detailed information of the project, a perfect solution can not be recommended.
