Type and Use

P-Boost by Aptus Plant Tech is an organic-mineral flowering additive based on phosphorus to be used during flowering. Suitable for all types of substrates and automatic irrigation systems.

Benefits to the Plant

  • Phosphorus actively takes part in various processes in the plants, from genetic code transfer to root and leaf development.
  • A phosphorus deficiency causes delays in maturation, resulting in lower quality buds, and decreased resistance to pests and diseases.
  • During the flowering phase, phosphorus increases the size of the buds and contributes to the formation of cannabinoids and terpenes.

How to Use and Dosage

During the flowering phase, mix 3 to 5 ml of P-Boost for every 10 liters of water. Mix thoroughly. Apply through irrigation.
