MINERAL-CALMAG is a 100% water-soluble additive containing necessary plant-available forms of nitrogen (N), calcium (Ca) and magnesium (Mg). This formulation has been designed to prevent common deficiencies while buffering your feed water when growing in soil-less mediums such as coco, perlite, rockwool, hydroton or recirculating systems and/or using filtered sources of water. MINERAL-CALMAG can be used throughout the entirety of the vegetative and flowering stages of growth.
APTUS BASE ‘liquid’ contains zero calcium and must be used in conjunction with either MASSBOOST OR MINERAL-CALMAG. Deciding which APTUS CALMAG to use (MASSBOOST or MINERAL-CALMAG) is largely dependent on your growing method.
MASSBOOST is an organo-mineral product which leads to organic biofilm build-up when kept in a nutrient reservoir for more than 2-3 days. While MINERAL-CALMAG is 100% mineral, super clean and will never spoil, MASSBOOST contains beneficial L-Amino Acids and is the CALMAG of choice for growers mixing fresh feed daily and can also be administered via foliar application. MINERAL-CALMAG has excellent pH stabilising capabilities and is the CALMAG of choice for growers running longer reservoirs and recirculating systems.
