Aptus Massboost 1ltr
Calcium and magnesium are easily locked up or combined with other minerals in the growing medium forming what we call “junk salts”. This active behavior can be a problem when trying to dial in supplementation of calcium and magnesium for your plants.
Aptus takes a unique approach in that our calcium and magnesium are chelated with natural amino acids much like Peakboost and Finaleboost.
This makes the normally very open minerals be more or less directly available for assimilation into the plant.
Whereas most other calcium and magnesium products are classic mineral salt formulations, Massboost functions as a pure source for the plants’ optimum and continued health. Since there is next to no interaction with outside products, you can use Massboost for just 3 weeks in the bloom phase: weeks 3, 5, 7, and an optional fourth week in week 8.
