Using a High Yield Photoperiod to Increase Lettuce Production by 40%

Using a High Yield Photoperiod to Increase Lettuce Production by 40%

June 15, 2018

This LumiGrow study uses LED fixtures to examine the effects of photoperiod length on lettuce plants in a greenhouse environment. The results of this study demonstrated that a longer photoperiod resulted in up to a 40% increase in lettuce production compared to a shorter photoperiod with the same DLI target.

Effects of Spectral Ratios on Miniature Rose Growth and Morphology

Effects of Spectral Ratios on Miniature Rose Growth and Morphology

October 25, 2016

Winter months in California have a Daily Light Integral (DLI) of 10-20, which is inadequate for optimal plant growth. To address this challenge, Light Emitting Diode (LED) lamps are beginning to be used in preference over High Intensity Discharge (HID) lamps for their higher energy efficiency and longevity.

LED for Healing of Grafted Tomato Transplants

LED for Healing of Grafted Tomato Transplants

October 25, 2016

Grafted tomato seedling propagation must be optimized to increase production efficiencies. Grafting has several steps that include growing, grafting, healing, and acclimation. Healing is considered the most critical step. Healing is the joining of cambium between rootstock and scion to form vascular tissue and is commonly done under modified greenhouse conditions or inside healing chambers.
