The Effects of T5 Fluorescent vs. LED (F3 Spectrum) vs. LED (X5 Spectrum) for Two Lettuce Varieties using Identical Light Intensities

Experiments were conducted in a vertical growing system on two lettuce varieties (Red Oakleaf and Green Butter Salanova) under three different light treatments – fluorescent T5 lighting, Illumitex F3 LED spectrum, and Illumitex X5 LED spectrum.   Light intensity levels were matched for the three light treatments and all other environmental Read more…

Physiological Differences and Chlorophyll Content for Red and Green Lettuce Due to LED vs. Fluorescent Lighting

The physiological differences and chlorophyll content of lettuce grown under three different light treatments (fluorescent, F3 LED, and X5 LED) were investigated. These experiments were conducted in a vertical growing system on two lettuce varieties (Red Oakleaf and Green Butter Salanova) under the three different light treatments with all other Read more…

Increased Growth and Marketability of Two Lettuce Varieties Due to LED vs. Fluorescent Lighting

Experiments were conducted in a vertical growing system on two lettuce varieties (Red Oakleaf and Green Butter Salanova) under three different light treatments – fluorescent T5 light bars, Illumitex F3 LEDs, and Illumitex X5 LEDs. Environmental parameters and light-source wattages were identical for the three light treatments. Due to differences Read more…
