Yes, because it is a liquid concentrate, it is highly soluble and safe for use in hydroponic reservoirs, as well as soil and soilless growing media.
The 2-15-4 NPK ratio provides a concentrated dose of phosphorus, which is essential for energy transfer within the plant. This helps increase the size, fragrance, and color intensity of your flowers and fruits.
