Greenhouse Growing Goes Electronic With Online Tools And Education

Figure 1. e-GRO University allows you to watch pre-recorded lectures on greenhouse production topics when it is convenient for you.

The world around us is moving faster and faster everyday. Just think of what you can do with your phone these days. Talk, surf the web, check eMail, snap photos, shoot video, play games — the list grows everyday. In this article, I will cover some of the ways that growers can harness this fast-paced world and the technologies that go with it.
Do any of these describe you?

1) You went to college to learn to be a grower, but clothes styles have changed at least twice since you graduated.

2) You never went to college but you’ve been working in a greenhouse for years and learned with dirt under your fingernails.

3) You just got into this industry and are feeling overwhelmed with everything you have to learn.
Regardless of your level of expertise, many of us find it necessary to go back to the basics and re-learn, review or learn them for the first time. It makes us better growers when we do. The problem is that it usually isn’t easy, no matter how strong your motivation is. We pick up great information at educational programs and in magazine articles but it might be months before we get to apply the knowledge to grow a crop. It can also be difficult to see how it fits into the “big picture” of growing in a greenhouse. We get so focused on the topic being discussed that we lose sight of everything else that is happening around that topic.

E-GRO University Offers Free Education On Multiple Topics
Recently a new offering was added to the resources available at the website It is called e-GRO University. This is a unique opportunity for seasoned growers to brush up on the basics or for a new grower to learn basic concepts and techniques from the comfort of their own office, or even from their living room sofa with their tablet in hand.

Six university faculty (Raymond Cloyd, Kansas State University; Kim Williams, Kansas State University; Brian Whipker, North Carolina State University; Margery Daughtrey, Cornell University; Roberto Lopez, Purdue University; and Brian Krug, the University of New Hampshire) joined forces to develop this introductory greenhouse production course.

e-GRO University consists of dozens of lectures on topics in five categories: Greenhouse Management, Growth Management, Insects and Mites, Nutrient Management and Diseases. See Table 1 for a list of all available lectures. These lectures are usually between 10 and 20 minutes in length and can be watched in any order you wish.

Maybe the best part of e-GRO University is that it is free. Thanks to support from the Fred C. Gloeckner Foundation, you can watch these videos  as much as you want, completely free of charge. e-GRO University tries to give you the experience of being in a classroom without making you step foot on campus. In addition to hearing the speaker and seeing a high-resolution copy of the presentation, you also get to see video of the lecture, and you can even download the slide set of the lectures.

FloriCAST: Greenhouse Education Five Minutes At A Time
You may already be familiar with FloriCAST, an educational video series hosted by Greenhouse Grower that covers various greenhouse production topics in five minutes or less. Over the past four years, there have been more than 200 FloriCAST episodes that cover basic and in-depth topics.

This year, FloriCAST episodes have been contributed by 11 university researchers on subjects including annual and perennial production, pest and disease control and nutrient management. Upcoming episodes cover subjects such as biological control of thrips, and PGRs for growth management of herbaceous perennials.

Growers can have episodes of FloriCAST delivered to their inboxes every week by subscribing to Greenhouse Grower’s Benchrunner eNewsletter at can also browse previous episodes of FloriCAST in the Video section at

Online Calculators Save Time
There are several mobile apps and web apps available to make your life as a grower easier and to help you get the job done faster. PGR MixMaster, from the University of New Hampshire Cooperative Extension, and Plant Growth Regulator, by OHP, are mobile apps that will assist in calculating PGR dilutions. OHP’s calculator is available for the iPhone. It has the ability to calculate dilutions for its PGR products and provides product information for each.
PGR MixMaster will calculate dilutions for almost all of the major PGRs on the market and is available for iPhone, Android and Blackberry.

How would you like to carry a library of references with you wherever you go in the greenhouse? Having the internet at your fingertips is nothing new, but this app lets you take it a step further. John Dole at North Carolina State University has created a database of greenhouse-related articles from scientific literature, trade and association magazines/websites. This database, Floriculture InfoSearch, has decades worth of material, and is easily searched from  

Electronic books can also expand your mobile reference library. Available on a number of mobile devices, electronic books allow you to store bookshelves worth of information in your pocket. A few that are specific to the iPad include:

  • Poinsettia: Fertility Management and Pictorial Guide to Nutrient Disorders
  • Ipomoea – Troubleshooting Guide to Disease, Insect, Nutritional, and Physiological Disorders of Ornamental Sweet Potatoes

These can be found on the iTunes Bookstore or on

So whether you are early adopter or a bit of a luddite, give one more of these resources a try if you haven’t already. You may find they become a necessity in your greenhouse.

Generation Y’s Reluctance To Garden Linked To Fea…

The Rookie Gardener is easily spotted at a garden center by her nervous and unsure energy that’s as glaring as a scarlet letter, or by his exuberant, self-assured confidence that is only otherwise seen at a college fraternity party. They are our industry’s enigma, our Kryptonite, the treasure chest we cannot open. The Rookie Gardener’s reluctance to garden isn’t from our industry’s lack of targeted marketing or encouragement but from Millennials’ Fear of Failure (FOF). It is obvious that failure is a part of life, but we as a generation have been programmed to not expect or accept failure. Since early childhood, we were encouraged to always win, to do our absolute best at school every day, to beat the competition. “Focused on getting the grades or winning the game, these children have internalized the pressure, (which) paralyzes kids in their ability to take risks,” writes Holly Korbey in an […]

“The Field to Vase Dinner Tour is a series of meals set on flower farms across the country. Each dinner is curated by a local chef and floral designer, highlighting the region’s produce and flowers. This is the story of Santa Cruz, California.” These opening lines introduce “Field to Vase: Santa Cruz,” a new documentary filmed, written and produced by the Los Angeles-based husband-and-wife team, Hyunsoo Moon and Haejung Kim. This past June, Haejung and Moon traveled to Santa Cruz in pursuit of a visual narrative that had captured their creative imaginations. They were enamored with the storytelling potential of the Field to Vase Dinner Tour and wanted to document their observations on film. The result of their efforts is “Field to Vase: Santa Cruz,” a documentary about the American grown flower movement and the people involved in the floral renaissance that is taking place on farms and in flower […]

A dynamic discussion during Cultivate’15 between growers, horticulture professors and both current students and recent graduates, provided some insight on how grower operations can attract the next generation of growers, and what’s important to make them stay once you hire them. The session, “Attracting the Next Generation of Industry Professionals,” featured a panel including Dr. Peg McMahon of The Ohio State University’s Horticulture and Crop Science Department, Dr. Marvin Miller of Ball Horticultural Co., Dr. Brian Jackson from North Carolina State University’s Department of Horticulture, Lloyd Traven of Peace Tree Farm, Douglas Schuster of Kingwood Center and Courtney Crawford of Millcreek Gardens. The preface for the session is something many industry professionals have lamented for years now — enrollment in college horticulture programs is dropping, and university programs are losing funds or disappearing. Much of this may be attributed to the perception among potential students and their parents that horticulture means […]

Retailer To Grower: Why Aren’t Garden Stores Letting Gr…

Have you ever sat around at a family gathering and heard someone recount a story from your childhood, except knowing your own version of the story, it’s something that casts an entirely new light on everything you think you experienced? It seems like that dynamic happens a lot between growers and retailers. Both sides know the same story, but each version is so different, it’s like two unconnected stories. This came to mind when I was talking with a regional grower, Elmer Grosser, who owns Cincinnati-based Diefenbacher Greenhouses. The operation serves about 50 customers — an even mix of local garden stores and landscapers. Grosser first came to my attention last fall, when one of his customers, Chris McKeown of Bloomin’ Garden Centre, told me I needed to call Grosser, because he was a great example of a grower who cares about retail. When Grosser and I connected, he was […]

Smith Gardens Is Developing Growers With A New Initiati…

Finding enough qualified growers has long been a problem in the industry, but it’s one that Smith Gardens is working to solve, at least locally. The operation, which ranks No. 22 on Greenhouse Grower‘s Top 100 Growers list, is the largest in the Pacific Northwest, and spans more than 50 acres of greenhouses and 50 acres of field growing over four locations in Washington, Oregon and California. As a 112-year-old family business that recognizes the need to invest in its future, Smith Gardens has made its Cultivating The Future initiative a corporate priority to attract young people to careers in the horticulture industry. Don Spence, the production manager at Smith Gardens’ Aurora, Ore., location, started working with local schools years ago. The operation expanded its program to local community colleges, and this year Smith Gardens worked with the American Floral Endowment to set up an internship program, and hosted an […]

One of the greatest parts of my job is having the opportunity to honor ingenuity in breeding, marketing and innovative growing in this industry at Greenhouse Grower’s Evening Of Excellence, a premier event held during Cultivate in July. The work leading up to the event is just as rewarding, from attending California Spring Trials to see all of the beautiful new varieties released to the marketplace to inspire consumers and solve problems for growers, to selecting the best of the best varieties for Medal Of Excellence In Breeding Awards. I humbly learn about and choose the Marketing and Industry Achievement Awards through industry nominations, and serve as a member of the selection panel for the Grower Of The Year Awards, on which we review nominations from people across the industry about creative, hardworking, dedicated operations and individuals who not only love their work but also live it.

There seems to be a constant stream of content in the media about Millennials and their habits and characteristics, particularly as consumers. But, what if they’re not the ones to be focusing on? A recent article in Food Business News is saying that they’re not. Instead, it suggests shifting the focus to the next generation. The article states that, according to bestselling author Matt Walsh, the most disruptive group of future food consumers was born in 2007. With gardening consumers becoming increasingly interested growing their own food, changes to the food industry will likely impact the horticulture industry, as well. “If you understand how an 8-year-old thinks, you’re a long way toward really understanding a transformative change in consumer behavior,” says Walsh, CEO of innovation research lab Tomorrow, during a July 13 presentation at the Institute of Food Technologists’ annual meeting and food exposition in Chicago. When an 8-year-old makes […]
