Horti Fair Still Quite The Show

Horti Fair Still Quite The Show

The exhibitor count at this year’s Horti Fair is down dramatically from 2008. One exhibitor I spoke with mentioned the number of exhibit halls being used is down from 11 in 2008 to seven this year. Still, if horticulture is your field, Horti Fair is the place to be.

I spent the day visiting as many of the exhibit halls as I could, but the majority of my time was spent in Horti Fair’s House of Technology. Willem van der Loo, Horti Fair managing director, piqued my interest when he spoke of growers making an additional living producing and selling electricity. I was curious how growers were producing electricity and how many of them were selling it.

Aroen Bechan, a representative from a Dutch electric company called Endon that helps growers sell electricity, offered me some answers. Bechan explained how many Dutch growers have turned to combined heat and power (CHP), also known as cogeneration or generating power and thermal energy from a single fuel source.

“It’s a plant that also uses natural gas but produces half the amount of heat,” Bechan says. “This means that you must use twice the amount of gas to make the same amount of heat. But a generator produces up to 43 percent of electricity. This makes the total return 93 percent for each cubic meter of gas. The benefits for the electricity are high enough to compensate the additional gas and investment and also covers a reduction compared to use gas in a boiler.”

Van der Loo views the CHP usage as one of the most impressive technological Dutch developments growers are using.

“Technical solutions, for instance, cut costs in power use,” van der Loo says. “There are growers who find a solution doing just that, and they grow their own power. In some circumstances, there are growers who sell the power back to the public network or to the power producers. There are days in the year where growers earn more by selling electricity than effectively selling cucumbers or paprikash.

“In these difficult economic times, if you are ahead in your technical developments and automation, you’ll probably have a better chance to survive.”

  1. I still do not understand why governments are not suporting CHP in north America and power suppliers are against it. It’s a no brainer I think.

  2. The equipment for cogeneration is VERY expensive. Your boiler equipment actually performs better if it is used 24/7 365 days a year. However our government sets the price of electricity abnormally low (is that a supprise?) So until energy policies shift cogeneration is not profitable in the US

4 Reasons Retailers Snub National Brands

Greenhouse Grower’s lead editor, Laura Drotleff, and I got into a debate about why garden retailers, especially independent garden centers, snub marketing efforts from breeders and growers. She was very much on the breeders’ and growers’ side, expressing frustration about how limited retailers’ vision can be on the topic. I’ve reported on the garden retail side of the industry since 1998, about the same length of time Laura has reported on growers. I’ve heard a lot of retailer views on this, so allow me to share the most common reasons why retailers decline free marketing: Costs. While the marketing materials are free, and sometimes advertising, participating in these projects usually requires minimum orders. From a grower’s perspective, the minimum orders are reasonable. If garden stores promote a plant line, they need to have enough supplies to satisfy demand. From a retail perspective, if inventory reports show a plant line can […]

Let’s Talk About Starflowers. Why Is Pentas Not More Popular?

It is good to talk about production techniques, performance results and then to see how our friends garden. Diversity of plant material has always been a strength in American garden centers, and we should never run out of plants to get people excited. However, perhaps people are tired of Petunias or Callas or Geraniums, but we will never run out of options to put in front of them. One plant that is often overlooked is Pentas, a fabulous summer crop for late spring sales. These are heat-tolerant plants, and growing them below 65°F in the greenhouse results in significant delay. Fertility should be at least 150ppm nitrogen, but avoid ammonia in the fertilizer. Plants are best grown at a somewhat higher pH than usual, between 6.4 to 6.8. For best presentation, pinch out the center bud. Side flowers will bloom together, and plants will walk off the shelf. Garden centers […]

Spread Your Risk Beyond Spring Sales [Opinion]

Growers who participated in Greenhouse Grower’s 2015 Spring Crops Recap Survey said they have had enough of the uncertainty that the weather brings. They said it’s time to build up sales in other seasons like fall so we’re not so dependent on spring. As a couple of wholesale growers, both from the Southeast, very eloquently stated, our industry has mastered squeezing everything we can out of the spring season. And while this year happened to be a very successful one, thanks to the improving economy and elevated consumer confidence, they said, “now is no time to celebrate.” “Spring is still Christmas in the horticulture industry, but we have done such a good job focusing on spring that we have neglected other seasons,” one grower said. “Having so many eggs in the spring basket is dangerous. Fall will never be what spring is, but having a solid second season is in […]
