The Spectral Control Guide was created by the LumiGrow Research Team to outline factors that should be considered when using spectrum control to grow Cannabis in a sole source environment. Working in-house and with research [...]
Terpenes are an almost ubiquitous group of organic metabolites, produced mostly by plants, but also by some insects. Most of the terpenes found in flowers are aromatic and contribute heavily to the smells we associate with flowers both [...]
Poster – Light Emitting Diodes as an Alternative to Cool White Fluorescents for Healing of Grafted Tomato Transplants
Previous work determined that light during the healing period influences morphology and quality of grafted tomatoes. Cool white fluorescent (CWF) at a photosynthetic photon flux of 100 μmol·m-2·s-1 is recommended for healing chambers. Light emitting diodes (LED) make possible optimizing the spectral requirements for healing.
Poster – Effects of Adjustment to Spectral Ratios of Supplemental LED Lighting on Miniature Rose Growth and Morphology
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.
Recent increases in sole-source production of high value crops demands an increased understanding of light spectrum on plant morphology in order to optimize propagation, growth, and yield of plants. Traditionally, indoor cannabis production has primarily used High Pressure Sodium, or HPS, however the recent introduction of LED lighting has allowed for spectral control coupled with increased energy efficiency.
Poster – Searching for an Optimum Supplemental LED Intensity for Winter Production of Cut Gerbera at Northern Latitudes
At higher latitudes, cut flower growers rely on supplemental lighting for maximizing production in the darker months. Horticultural LEDs have been proven to produce similar or better crops (in terms of yield and quality) compared with HPS; while also having longer lifespans, higher energy efficiencies & can be controlled in terms of spectral distribution & intensity. This project sought to determine the optimum light level for cut gerbera production during the 2015-16 supplemental lighting season (ie. Nov. thru Feb.) at higher latitudes
