Is Wood A Viable Media Component?
Peat moss is an absolute necessity for greenhouse growers. The industry simply couldn’t do without it. But the cost of shipping peat across Canada to southern parts of the United States is forcing Southern growers to look for resources that are capable of supplementing their bread-and-butter growing media component. One resource to which growers are slowly turning is wood. Wood, by no means, is a peat replacement. Plus, it’s a resource nursery producers have historically relied on more than greenhouse growers. Still, horticulturists are discovering that wood, when used in the right ratio to peat and for the right crop, is a serviceable growing media component. USDA and university researchers, for example, have grown a wide range of cropsâ€“annuals, perennials, tropicals and woody ornamentalsâ€“using processed whole pine trees as a growing media component. And the results of this research are enlightening. “Commercially, I think we could switch to 50 percent […]

New Products: Media And Amendments
Berger’s Organic Germinating Mix This mix uses a combination of high-quality, fine Canadian sphagnum peat moss, fine perlite and fine vermiculite. OM2 will provide an ideal root environment for a uniform germination and rapid root development. Jiffy’s Preforma Manufactured from high-quality substrates, Preforma is held together with a unique binding agent. The Preforma plant plug is suitable to work in any highly automated greenhouse environment. Acadian’s New Bale Size Acadian Peat Moss is now offering professional grade sphagnum peat moss in a 110-cubic-foot Acadian Giant bale.

Fafard’s New Formulations
Since 2008, when the Fafard Research Leader Program launched, interns have been conducting research to help design new growing media formulations at large, commercial greenhouse operations across the United States. Essentially, research projects have examined how different raw materials, soil amendments and additives used in media perform in different greenhouse settings. Fafard, then, has used much of that research to design a pair of growing media options that are now available to growers: Fafard’s Young Plant Mix, a combination of peat, perlite and vermiculite that’s packaged in compressed bales; and mixes that directly incorporate Scotts’ new Osmocote Start controlled-release fertilizer. “We’ve been doing the research and development within the Fafard Research Leader Program the last two years, and it’s been very successful,” says Bruce Adams, Fafard marketing manager for grower products. “With the support of Syngenta, we’ve been able to launch two new products for this past season. Typically, you’d […]

Omni Growing Solutions is offering a new plug product for young plant production, Aero NT. The plug is designed to hold its shape without the use of a wrapper. The product line has been in development in Germany for the last 10-12 years. Plugs are produced in a batch-mix system using a typical growing mix, but a binding agent is added to help the plugs hold together easily. Plugs are pre-dibbled and according to general manager Bill Maartense, plants have shown 20-25 percent shorter rooting time in tests. Omni Growing Solutions, an independent offshoot of Dummen will be opening a production facility in Ontario in November. The plan is to serve primarily Dummen rooting stations next year, and to open things up to the larger grower audience the following year.

Fafard Gains Right To Add Osmocote Start To Mixes
Fafard is part of Spring Trials at Syngenta Flowers in Gilroy again this year, and the company’s latest development is that it now has the rights to incorporate Scotts’ Osmocote Start into its growing mixes. Osmocote Start is a controlled-release fertilizer, and growers interested in Fafard’s Osmocote Start mixes can approach either Fafard or Scotts for technical support. “The great benefit of this product is it reduces the amount of water-soluble fertilizer growers will need–in some cases eliminating it entirely,” says Hugh Poole, director of technical research for Fafard. “It’s another way of getting a fast crop in. it’s going to reduce leaching, groundwater contamination and it’s actually going to reduce the total fertilizer requirements for the grower.” Less algae growth in the greenhouse is another benefit, Poole says, because water-soluble fertilizer won’t be making its way onto greenhouse floors. Osmocote Start is a fully coated N-P-K plus micronutrients controlled-release fertilizer. Its […]

Stone Wool As A Substrate
HortiPro and Saint-Gobain CultilÃ¨ne, a Netherlands-based substrate company, recently joined forces, making CultilÃ¨ne’s stone wool substrates more easily available to U.S. growers. Martin Boerema, who’s a senior consultant with HortiPro, is in charge of technical support for CultilÃ¨ne here in the United States. Propagators, cut flower growers and high-tech vegetable producers are among the growers stone wool substrates make sense, Boerema says. Stone wool products are also among HortiPro’s product offerings, which include cocopeat, bark and other growing media. You can learn more about the two companies at HortiPro.com and Cultilene.com.

Alternatives To Peat
The American Floral Endowment recognizes that alternatives to peat must be developed to meet environmental concerns pertaining to mining of peat bogs. AFE shares research it funded and Virginia Tech University conducted. Robert Wright and Brian Jackson, both of Virginia Tech’s Department of Horticulture, wrote this report. Background It is recognized that alternatives to peat must be developed to meet environmental concerns pertaining to mining of peat bogs. Also, peat supplies can be limited by wet weather conditions that restrict harvest during certain times of the year. These concerns, coupled with increasing fuel costs, have led to increased costs of peat substrates. Therefore, there is an increased interest in less expensive and readily available substitutes. Our research has shown that a pine tree substrate (PTS) manufactured by grinding loblolly pine trees with a hammer mill makes an excellent greenhouse container substrate. The trees can be ground to the correct particle […]

Ellepot Papers Now VeriFlora Approved
Two types of papers Ellepot USA uses–the Ellepot EP and VP papers–are now certified as VeriFlora Approved Input Materials. According to VeriFlora, some of the sustainable attributes related to the use of Ellepot EP and VP papers include: –Degradable papers produce less waste and environmental impact than alternatives such as plastic pots.–EP and VP papers are Forest Stewardship Council (FSC) certified from well-managed forests.–Ellepot paper is, in many cases, sustainable cheaper than plastic pots. –One roll of paper is equivalent to about 17,000 4-inch pots. One pallet of paper holds 32 times that, or 540,000 pots, taking up much less space (and weight) on a pallet, allowing greater efficiency in transportation.–The Ellepot reduces the amount of planting media needed and avoids root shock when transplanting by keeping the soil secured around the root system. “Ellepot USA is proud to have two of our paper types approved as VeriFlora input materials,” […]
