Early results from fertilizer trials in Hort Americas’ research greenhouse show knowing the levels of nutrients in fertilizer solutions can go a long way in avoiding problems with deficiencies and toxicities.


Fertilizer trials look at leafy greens, herb growth in hydroponic production systems

Hort Americas has retrofitted a 12,000-square-foot greenhouse in Dallas, Texas, for the purpose of studying edible crop production in a variety of hydroponic production systems. The greenhouse is also being used to demonstrate products offered in the company’s online catalog.

Tyler Baras, who is the company’s special projects manager, is overseeing the trialing of leafy greens and herbs in five different production systems.

Hydroponic fertilizer

Hort Americas offers a variety of organic and inorganic fertilizers including its own specially formulated hydroponic fertilizer. Hort Americas 9-7-37 Hydroponic Fertilizer is specially formulated for growing leafy greens, culinary herbs, microgreens and other crops in hydroponic systems.

Hort Americas designed this water soluble fertilizer to deliver the essential nutrients for efficient uptake by the plants’ root system. It can be used as a constant feed or as a supplement. The fertilizer is available in either a 25- or 5-pound bag.

Hort Americas developed this unique fertilizer in cooperation with CEA hydroponic specialists, academicians and researchers to meet the nutritional requirements of edible crops produced by hydroponic growers. Hort Americas recommends that hydroponic growers have their water tested by a professional water analysis laboratory to determine its nutrients, pH, EC and total alkalinity prior to using its Hydroponic Fertilizer.


Grodan Cress Plate

The Grodan Cress Plate is the optimal substrate for the production of microgreens and bulk harvested leafy vegetables and culinary herbs in vertical farming production systems. These thin sheets of Grodan stone wool, available from Hort Americas, are specially developed for quick growing crops that need minimal substrate.

The plates deliver a uniform water level that provides quick and easy germination. The plates, which are the thinnest Grodan product on the market produce even crop development.

The plates are available in two sizes: 49.5 x 24 x 1 cm, which fits 10/20 trays and 60 x 50 x 1 cm. The 10/20 tray size plates are available 90 per carton; the 60 x 50 size plates come 50 sheets per carton.


Feedback sought on proposed horticultural lighting label

Horticultural researchers at several U.S. universities have developed a proposed standardized product label that would allow for the comparison of manufacturers’ lamps used for all horticultural applications. The label includes the efficacy (output of photosynthetically active radiation per unit of electric power consumed measured in micromoles per joule (μmol/J), conversion efficiency, photon flux output in key wavebands in 100 nanometer (nm) increments across the 300-900 nm waveband, the phytochrome photostationary state, and graphs of the normalized photon flux across the 300‐900 nm waveband, as well as the light intensity distribution at a specific distance from the light source.

The lighting researchers are asking for industry feedback on this proposed performance label that they believe would provide uniform information on lamps used for horticultural applications.



Read Urban Ag News Issue 15, The Lighting Issue!

We are proud to be a sponsor of Urban Ag News. There are great articles in the latest online magazine issue including the cover story which focuses on the lighting research being conducted at Wageningen University in the Netherlands. Leo Marcelis, head of chair group horticulture and product physiology, talks about how university researchers are studying the effects of LED lights on the growth, flowering and fruiting of vegetable and ornamental plants in controlled environments.
