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 system
Plant 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.
Following an EU legislation, which forces growers to recycle 100% of the waste water, Haifa has developed Multi-K™ Reci, a potassium nitrate with near-zero sodium that ensures low sodium levels in recycled drain water. Most plants won’t take up sodium and therefore sodium concentration in the feeding solution will increase during time and may harm the crops.
With a maximum value of 300 ppm sodium, Multi-K™ Reci contains up to 90% less sodium than any other potassium nitrate fertilizers in the market. It prevents the increase of sodium levels in the feeding solution and by that ensures healthier crops.
Haifa VitaPhos-K™ Highly efficient Phosphorus source
Phosphate 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 VitaPhos-K™ provides phosphorus in the form of polyphosphate and enables a true improvement in the growing results. Haifa VitaPhos-K™ improves phosphorus uptake and also boosts plants vegetative growth. The phosphate in Haifa VitaPhos-K™ remains stable in the feeding solution at high pH and does not lead to any precipitation with other elements at high concentrations. The polyphosphate even ensures that precipitated elements will be re-dissolved, thus achieving improved efficiency of the elements provided.
Haifa GrowClean™ Keeping irrigation system clean
After 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 formatio of deposits, all mineral elements are available for the crops.
Haifa Cal™ GG Greenhouse-grade calcium nitrate
Calcium 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™ GG is an ideal source of plant-available calcium for all greenhouse crops. Along with calcium, it provides nitrate-nitrogen, which enriches plant nutrition and improves the efficiency of calcium uptake. Haifa Cal™ GG is ideal for highly-efficient applications by Nutrigation™(fertigation) and foliar sprays.

Haifa Cal™ Prime Calcium nitrate with near-zero sodium
In soilless growth media and hydroponics, nutritional solution’s pH must be carefully balanced. Any uncontrolled addition of ammonium to the solution will lower the pH in the root zone to an adverse level. In addition, accelerated uptake of ammonium by the plant may result in toxic effects. Near-zero ammonium level makes Haifa Cal™ Prime the ideal calcium fertilizer for soilless crops. Haifa Cal™ Prime assures safe supply of essential calcium with no harmful side-effects and is more concentrated than other calcium nitrate products; therefore, application volumes can be significantly reduced while the plants enjoys optimal calcium nitrate levels and the grower benefits from direct saving on energy and labor.
