(1 customer review)




1 ,5, 50 lb bags

The is the water soluble fertilizer for hydroponic use.
Due to new requirements, we are no longer able to ship fertilizer outside the USA.


The recipe for use in a hydroponic system is 12 grams Masterblend 12 grams calcium nitrate 6 grams magnesium per 5 Gallons



Greenhouse grade. Easily used in drip line systems. Not to be used as a foliar feed fertilizer. White granular pellets devolve easily in warm water. Should be stored in a air tight container or you will end up with one, big, white, rock.

As of 1978, only 170,000 tons/year were produced for applications in fertilizers.[2] The fertilizer grade (15.5-0-0 + 19% Ca) is popular in the greenhouse and hydroponics trades; it contains ammonium nitrate and water, as the “double salt” 5Ca(NO3)2.NH4NO3¬∑10H2O. This is called calcium ammonium nitrate.

A $ 17.05 flat rate box holds 1 to 4 ‚Äď 5# bags or 1 ‚Äď 25# bag and ships anywhere in the US. A $ 10.40 flat rate box will hold 1 to 2 ‚Äď 1# bags and ships anywhere in the US.
