Alchimia presents Stack by Athena, an organic fertiliser ideal as a supplement to boost the flowers' growth, size and density. This organic nutrient is formulated with plant extracts based on algae that provide a full spectrum of vitamins, hormones and amino acids.

Stack enhances vigorous growth of both the main branch and secondary ramification. When applied in the flowering stage, it boosts flower production, density and fleshiness.

Foliar application helps to correct minor potassium deficiencies.
