Massboost is a highly concentrated organo-mineral Calmag that contains calcium, magnesium, nitrogen, sulphur and L-amino acids 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.

Organo-mineral calmag & bud booster

How To Use:

Add MASSBOOST to your reservoir every feeding as per feed schedule. If using MASSBOOST as a bud booster additive with another regime, add 0.5 ml per 1L in weeks 3, 5 and 7 of the flowering phase. When mixing with any phosphorus supplements (PEAKBOOST or mineral fertilisers), be sure to mix one into the solution before adding the other to minimise the chance of forming calcium-phosphate bonds which render both unavailable to the plant.
