Barrier TOP CROP is an organic fertilizer designed to strengthen plants at all stages of growth. Thanks to its formula rich in silicon and potassium, it improves nutrient absorption, strengthens cell walls, and increases resistance to pests in cannabis cultivation .

Barrier TOP CROP is a plant strengthener formulated with potassium silicate, which acts as a natural defense barrier for plants. This completely water-soluble product can be applied to crops grown in soil, coco coir, or hydroponically, and is fully compatible with automatic irrigation systems.
One of its main advantages is its ability to improve nutrient assimilation, strengthen cell walls and raise chlorophyll levels, which enhances photosynthesis and, in turn, increases CO₂ absorption.
This metabolic effect results in stronger, healthier, and more productive plants. Its high potassium (4.63%) and silicon (9.2%) content makes Barrier TOP CROP especially effective during the flowering phase, helping to develop denser buds as the branches can support their weight without breaking.
Furthermore, it is an excellent pH regulator, especially in hydroponic solutions thanks to its alkaline pH (11.67). Regular use strengthens plants' resistance to pests, fungi, and adverse weather conditions.
It is part of the TOP CROP fertilizer range, recognized for its effectiveness and compatibility with all types of crops.
Barrier TOP CROP is very versatile and can be applied in two ways:
