Soilless greenhouses represent the edge of horticulture technology.
At Haifa we know the challenges farmers are facing while growing in soilless greenhouses: small volume of growth medium and water with low capacity to retain plant nutrients requirements.
Perfect match of plant nutrition to the crop growth needs
Haifa has developed a pioneering range of soluble fertilizers that provide soilless crops with precise nutrition, maximizing yields and profitability.
Haifa's nutritional solutions precisely meet your crop's needs at any growth stage. Haifa specialty products are composed of pure plant nutrients and they are free of chloride or sodium. Thanks to Haifa’s innovative products, the water pipes and drippers will remain 100% clean and efficient. Decades of research and worldwide activity have made Haifa a genuine expert in plant nutrition, from development to supply and application.

Advanced fertilizers facilitate greenhouse maintenance and crop production
Modern greenhouse growers are facing the challenge of providing efficient plant nutrition while recycling drain water and keeping the watering pipes clean. With the right fertilizers, these goals can be fully achieved.
| Multi-K™ Reci Keeping sodium out of the systemPlant nutrition used in soilless and hydroponic greenhouses must be efficient, precise, and contain only essential nutrients. Non-beneficial elements may accumulate in recycled drain water systems, changing parameters such as pH and EC levels, and putting the crops at risk. |
 | Haifa VitaPhos-K™ Highly efficient Phosphorus sourcePhosphate in traditional fertilizers such as MAP and MKP is in the form of orthophosphate. In this form, it can easily compound with calcium, magnesium and iron, causing precipitation in the system. It is then no longer available for the plant and can even cause clogging.

 | Haifa GrowClean™ Keeping irrigation system cleanAfter the introduction of polyphosphate, growers have noticed that while higher dosage of polyphosphate give extra vegetative growth to the plants, polyphosphate in low dosage keeps the irrigation system clean from participant. However, the relatively high pH of the product creates a need of adding acid into the fertilizer tank. Haifa GrowClean™ eliminates this need. Haifa GrowClean™ contains 50% polyphosphate but the pH of the product is neutral, so there is no need to add acid. Haifa GrowClean™ is also sodium-free, and this makes it a good product for keeping the irrigation system clean, and at the same time 100% safe for plants. With no formation of deposits, all mineral elements are available for the crops. |
 | Haifa Cal™ GG Greenhouse-grade calcium nitrateCalcium is a “quality nutrient”, vital for yield quality and prolongs shelf life. As calcium is not mobile in the plant, it must be supplied throughout the growth season to keep adequate levels in the plant tissues and to ensure proper development.
|
 | Haifa Cal™ Absolute Nitrogen-free calcium fertilizerHaifa Cal™ Absolute is an advanced calcium source that provides a highly efficient and flexible solution for calcium nutrition under a wide range of conditions. Delivering calcium with zero nitrogen, it enables precise control over calcium fertilization—without contributing unnecessary nutrients to the solution. This makes it the ideal choice when calcium is needed but nitrogen should be limited, such as during the fruit ripening stage. |
