“CEA agriculture has increased in importance in 2020, with restraints on traveling, shipping and transportation,” says Triston Hooks, Research Associate at Texas A&M AgriLife. However, there are also some issues around it. Triston states that both indoor and greenhouse growing typically block or lack UV…

The plant uses barely fifty per cent of the sun’s radiation energy for photosynthesis. This part of sunlight is called PAR-light. Within this range all the wavelengths have a function, contrary to what was once thought. Plants use light for two things: photosynthesis and photomorphogenesis (control of…

In this study, we sought to evaluate and compare the effects of constant and dynamic lighting on red and green leaf lettuce (Lactuca sativa L. Red Cos and Lobjoits Green cos) cultivated in a controlled environment. Plants were illuminated with the combination of red 662 and 638 nm, blue 452 nm, and far-red 737 nm at 16 h photoperiod and constant daily light integral (DLI) of each component. Five constant or dynamic lighting treatments were performed: (BR) constant flux of both B452 and R662; (B*R) constant flux of R662, but the DLI of B452 condensed in 8 h in the middle of photoperiod doubling the PPFD of blue light; (BR*) constant flux of B452, but the DLI of R662 light condensed in the middle of photoperiod; (BdynR) constant flux of R662, but the flux of B452 varies in the sinusoidal profile during 16 h photoperiod, imitating diurnal increase and decrease in lighting intensity; and (BRdyn) constant flux of B452, but the flux of R662 varies in sinusoidal profile. The lettuce’s response to dynamic lighting strategies was cultivar specific. Dynamic lighting strategies, mimicking natural lighting fluctuations, did not have a remarkable effect on photosynthesis and antioxidative parameters, but the dynamic flux of blue light component had a pronounced effect on higher macro and microelement contents in lettuce leaves.

One of the most critical challenges—whether for greenhouse managers or for horticulture aficionados—is to provide plants with enough photoperiodic sunlight for effective photosynthesis, so that they can grow optimally regardless of the geographical location and climate. Winter months even in supposedly…

In relatively hot climates like most of Australia, using an automated Shade or Energy Screen is an indispensable tool, but it is also a compromise – it’s really good at cooling the greenhouse, or really good at keeping it warm, but it can’t do both very well. So, Growers are increasingly opting for Double Screens – one screen…

It is well-known that artificial lights can significantly improve crop production. Despite this, little research to date has examined how new light environments impact greenhouse crop protection – both the good bugs and the bad. We know that light impacts arthropods (insects and mites), such as when mayflies are drawn to streetlights, and moths to flames. But how important is it really to greenhouse pest management?

In order to inhibit spindling growth and improve quality of cucumber seedlings under low irradiance, effects of supplemental light-emitting diodes (LED) light (SL) on morphological and physiological characteristics of cucumber seedlings at different growth stages under extremely low irradiance (ELI) were…

In plant factories, light is fully controllable for crop production but involves a cost. For efficient lighting, light use efficiency (LUE) should be considered as part of light environment design.   The objectives of a new study were to evaluate and interpret the light interception, photosynthetic rate, and LUE…

“UbiGro is essentially a layer of light in a greenhouse,” according to UbiQD’s chief of product, Matt Bergren, who enthusiastically described how the company’s UbiGro luminescent greenhouse film and its embedded nanotechnology facilitate light management in greenhouse settings. Based in New Mexico and established in 2014, UbiQD is harnessing nanotechnology for various applications, one of which is the optimization of greenhouse light quality through its UbiGro luminescent greenhouse gilms. UbiGro films use quantum dots to convert UV and blue photons to longer wavelengths, resulting in the emission of orange/red light. Otherwise stated, UbiGro is a photoluminescent film that glows when illuminated with sunlight due to the conversion of short wavelengths to long wavelengths. This allows growers to harness various wavelengths for photosynthesis and improve crop yields.

The use of high-tech greenhouse facilities and vertical farms for fruit and vegetable crop cultivation is skyrocketing in certain parts of the globe as a response to increased demand for fresh produce, less reliable weather conditions and the rising scarcity of cultivable farmland. Precision farming ensures all-year production, higher yields, improvement in product quality and higher marketable value. Modern indoor farming technologies offer the possibility to boost plant density as compared with open field cultivation. However, failing to provide adequate lighting at the necessary points in a dense canopy is bound to result in suboptimal crop yields. For instance, using more toplight modules will only lead to a bigger electricity bill while the lower parts of the plants will still not receive the proper amount of light.

Ultraviolet-C (UV-C) radiation is efficient in reducing the development of diseases in many species, including strawberry (Fragaria × ananassa). Several studies suggest that UV-C radiation is effective not only because of its disinfecting effect but also because it may stimulate plant defenses. In a new…

Four light treatments (W: white light; EOD-B: end-of-day enhanced blue light; EOD-FR: end-of-day supplementary far-red light; EOD-UV: end-of-day supplementary ultraviolet-A light) were designed to explore the effects of end-of-day (EOD) lightings (30 min before dark period) on leaf color, biomass and phytochemicals accumulation in two lettuce cultivars (Lactuca sativa cv. ‘Red butter’ and ‘Green butter’) in artificial light plant factory. EOD-FR stimulated the plant and shoot biomass of two cultivars, and EOD-B suppressed the growth of ‘Red butter’ but induced higher biomass in ‘Green butter’. EOD lightings generated brighter, greener and yellower leaf in ‘Red butter’ at harvest, but the highest lightness and the deepest redness of ‘Green butter’ leaf were observed in the middle growth stage. ‘Red butter’ had prominent higher contents of chlorophylls and carotenoids, while these pigments showed less sensitivity to the interaction of cultivars and EOD lightings. EOD lightings impeded the accumulation of anthocyanin in two cultivars, except EOD-UV slightly increased the anthocyanin contents in ‘Green butter’.

Growers generally have two options when it comes to horticultural LED spectrums – “full spectrum” or “broad-spectrum”, which appears as white light; and “red/blue spectrum”, which can appear as purple or pink light.
