Massboost
Bud Booster
Massboost is a highly concentrated supplement containing calcium. magnesium, nitrogen and sulfur to support healthy, vigorous growth through both veg and flower. Massboost is the calmag of choice for indoor and outdoor coco, peat and soil growers in run-to-waste systems.
For cultivators running hydroponic, DWC, recirculating or fertigation systems, use APTUS’ Mineral-Calmag.

When mixing with any phosphorus supplements (PEAKBOOST or mineral fertilizers), be sure to allow one to mix into solution before adding the other.
MASSBOOST prevents calcium and magnesium deficiencies while stimulating powerful fruit set and development. Calcium and magnesium are just as important as the macro elements nitrogen (N), phosphorus (P), and potassium (K) you see on the front of every fertilizer label. BASE grow and bloom NPK fertilizers only include small amounts of calcium and magnesium, which in high intensity growing environments can quickly be consumed by your plants. MASSBOOST fixes this problem of under-supply by providing large amounts of plant available calcium and magnesium.
MASSBOOST is best used in soil, coco, or peat drain to waste applications. If you need a calcium & magnesium supplement for use in clean recirculating or fertigation applications, use MINERAL-CALMAG.
Calcium along with the silica in FASiLITOR largely comprises the structure of the plant cell wall which gives the plant it’s physical shape. An uninterrupted supply of calcium contributes to healthy flowers and leaves, strong stems and continued formation of healthy plant tissue. Calcium’s impact on plant health can be seen by preventing blossom end rot, underdeveloped flowers and a lack of necrosis on plant tissue.
As the plants undergo cell division forming new tissue, the increased supply of magnesium allows for continued production of chlorophyll in the leaves. Magnesium is the central element to chlorophyll which is crucial to the process of photosynthesis enabling the plant to turn sunlight into usable forms of energy.
Highly available, 100% water soluble and leaves no residue behind.
Provides calcium which improves firmness and structure of fruits during the flowering phase of growth.
Provides magnesium which is the central element to chlorophyll allowing photosynthesis to occur.
Provides the extra boost plants need during certain plant-development phases and other important natural bio-stimulants
Calcium Integral structural element to plant cell walls and thus overall physical plant structure.
Magnesium Element central to the formation of chlorophyll and thus essential for photosynthesis to occur.
MASSBOOST is the calmag of choice for indoor and outdoor farmers growing in soil, coco or peat.
Used as both a root drench and or foliar feed, indoor, outdoor and greenhouse cultivators will add MASSBOOST to their foliar regime for the last week of veg and first 2 weeks of flower to increase growth and prevent calmag deficiencies in hungry cultivars.
