Flourish

Ecothrive Flourish is an ultra-purified seaweed extract produced through a proprietary processing technique that creates an extract clean and pure enough for use in hydroponic reservoirs — a quality most seaweed extracts cannot achieve due to contamination and instability issues. Unlike traditional seaweed extracts that foul reservoirs or leave residue, Flourish remains stable in solution for weeks.

This 100% natural and Soil Association-approved biostimulant contains bioactive compounds, phytohormones (cytokinins, auxins, gibberellins), amino acids, trace minerals, and natural polysaccharides from its seaweed base. These compounds enhance stress tolerance, improve germination and vegetative performance, boost flowering quality, and drive secondary metabolite production including terpenes and cannabinoids.

Apply throughout the grow cycle in soil, coco, and hydroponic systems. The reservoir-stable formula makes it one of the few organic biostimulants that works cleanly in recirculating hydroponics without fouling the system. Made by Ecothrive, UK — part of their premium organic product lineup alongside Charge.
