Gerbera daisies always bring a smile to your face with their bright colors and pleasing flower shape.

Krishikosh: Performance of Gerbera (Gerbera jamesonii Bolus) cultivars under hydroponics

Gerbera Majorette initially features 7 gerbeta, including one bicolor, and is ideal for use in 1-quart pots and larger with multiple plants. This beautiful plant features medium-large deep rose flowers held on short flower stalks above a compact mound of soft, feathery blue-green foliage. It requires shade to part-shade conditions and prefers consistently moist, well-drained loamy soil. Erik Runkle and Dr.


This symposium, which takes place only once every four years, serves as a platform for scientists around the world to share current research, exchange ideas and to establish collaborations.

The symposium was packed with quality information about the use and manipulation of light in horticulture. The total number of attendees was approximately Two of the most prominent topics were the use of light-emitting diodes LEDs and the production of plants indoors.

The symposium featured 52 oral presentations and 78 poster presentations. Also, four internationally recognized scientists participated as invited keynote speakers:. You can find more information at actahort. Marc van Iersel from the University of Georgia is working on a chlorophyll fluorescent-based biofeedback system.

The objective is to gedbera high photosynthetic efficiency and reduce electrical consumption. In other words, by measuring real-time chlorophyll fluorescence, the plant serves as the sensor to control the light intensity of gfrbera LED array.

For example, he has demonstrated that applying UV-B using irrigation booms increases the yield, plant hardiness, leaf thickness and transplant success of young seedlings. Kevin Folta from the University of Florida introduced the idea of pairing hydropknic genetics with LED technology in order to improve the overall production outcome a better and unique crop.

He also showed how one cultivar of edible microgreens is able to produce many different harvestable products long seedling, purple seedling, short, green, etc. Folta emphasized that plant breeding and light recipes should go hand-in-hand to improve indoor production systems. Another prominent topic in the conference was the use of LED lights for the increase of nutritional content of common horticultural crops such as lettuce, leafy greens and tomatoes among others.


An emerging topic hydroponkc this conference was the environmental impact of horticultural production in terms of carbon footprint CO2 emissions and energy consumption. Anja Dieleman from Wageningen University quantified the carbon-footprint of tomato greenhouse production when grown under HPS supplemental lighting and LED supplemental lighting.

Bugbee presented the following quote by Dr. We often think of photosynthesis as the main factor driving plant growth. However, photosynthesis by itself it is not a good indicator of overall plant growth. Here, the growth rate was better predicted by the yydroponic of leaf area and photosynthesis, and not by photosynthesis alone.

Another example is the increase of CO2 concentration in greenhouse production. Generally, when the CO2 concentration is increased, the photosynthetic rate also increases. However, if the higher concentration of CO2 is maintained for a long time days the plant can start changing its leaf anatomy and potentially develop fewer stomata cells, thereby reducing Hydroponid diffusion into the plant. With the current capacity to create customized spectrums using LEDs, scientists are now working to find the spectrums that will positively affect plant development and morphology to directly increase plant growth or other desirable characteristics.

Growers can later use that information to increase yield and profitability. On the last day of the conference, we enjoyed a technical tour of east Michigan. Overall, the conference was a unique and rich experience.

Paul Karlovich, director of research, has been trialing sole-source LED lighting with different crops in this shipping chamber since this past April. Raker has been looking at growing tuberous begonia and gerbera in the chamber as a solution to the struggles they often face growing them in the greenhouse.

Through this research, Karlovich is evaluating if they can improve productivity and speed up the crop time. In Litchfield, as in many other places in the Midwest, weather can be inconsistent at best, which complicates growing — even in a greenhouse.

Do I not water? One of the advantages of growing in a chamber is the consistency of the growing conditions. Light, water, CO2, fertilizer and temperature can be strictly controlled, and the weather outside becomes irrelevant.

In addition, Karlovich sees an opportunity to eventually automate many of the processes in the chamber. At this point, people still need to enter the chamber to make sure the plants are up to count and progressing well.

That is, once they find the best combination of light, water, fertilizer and other conditions to grow each crop in, labor needs would be reduced and productivity would increase. The capital investment in a project such as this one is not insignificant, and growers should carefully consider the costs and benefits just as they would with any other greenhouse expense.


In this case, electricity is the biggest cost that Raker is incurring.

The evolution of LEDs in recent years has been a big part of why Raker has been considering them for uses such as premium crop production. Raker is a year-round producer of products [and] have plugs growing every week of the year. Karlovich is also seeking out different crops that can be grown year-round in order to get the maximum return on the chamber and keep the facility up and running 12 months out of the year.

His advice to other growers considering undertaking a project of this type? Over the past 25 years, Battlefield Hhydroponic has innovated and invested in technology to maintain a strong business and weather economic downturns. In recent years, Battlefield has been focused on lighting, including trialing and implementing LED lighting in different growing areas. The company already had experience using high pressure sodium HPS lights in the greenhouse for some time for supplemental lighting or night extension.

But there were specific areas where they believed LEDs might improve production, especially in tissue culture propagation. This led to losses, inconsistencies and increased labor needs. The team decided to move their tissue culture propagation into a room with a controlled environment that utilized a sole-source lighting system about two years ago. Ideally, they would be utilizing the room year-round, Higginbotham says. Growers who are considering investing in LEDs need to understand the differences between the lighting types, such as intensity, spectrum and heat emission.

Have some really good personal experience and data before making the investment. Higginbotham educates himself about lighting using a range of sources, including lighting manufacturers.

Higginbotham is excited about the possibilities of LED lighting gefbera Battlefield. Now we have the ability to cut back on energy, [and] manipulate [the plant] with different spectrums of light. He recently hdroponic a trial that compared incandescent lights to LED lights in night interruption photoperiodic lighting of perennials, namely echinacea.
