Phosphorus Plus HESI is a mineral fertilizer designed to enhance bud fattening during the flowering stage of soil cultivation. Its high phosphorus and potassium content offers a more abundant yield, denser buds, and visible results in just a few days.

Phosphorus Plus HESI is a specific mineral booster for soil crops, developed to maximize flower production during the middle and final stages of flowering.
This product is applied from the fourth week of the flowering cycle and acts as a true bud fattener, providing phosphorus (P) and potassium (K) in ideal proportions for the formation of compact and heavy floral tissues. The formulation of this product has been developed by Hesi Fertilizers to ensure rapid and effective absorption, without residues or blockages in the root system.
The use of Phosphorus Plus HESI is recommended in combination with HESI Bloom Complex, forming a perfect duo to achieve superior yields in marijuana crops, both indoors and outdoors.
It is suitable for all types of varieties, including feminized and autoflowering seeds, and can be applied directly in soil or in pots. Although it can be used in drip irrigation, its use is reserved exclusively for soil crops.
For coco or hydroponic systems, the use of Hesi PK 13/14 is recommended. In addition, if combined with Hesi Boost and Hesi Super Vit, the effects are further enhanced, taking the crop to a higher level.
