Sonnenerde Bio Hanferde is a specialized Terra Preta-based organic soil designed for urban gardening and ideal for medicinal plants and cannabis cultivation, whether indoors, in grow tents, or greenhouses. Perfect for fabric pots, smart pots, and containers, it’s a "living soil" rich in organic matter and beneficial microorganisms that support sustainable growth. Unlike sowing soil, Bio Hanferde is meant for transplanting young plants, providing a nutrient-rich, ready-to-grow environment from seedling to harvest. For even better results, check out the brand’s Bio Faser. This soil contains stable, climate-positive carbon, certified and stored long-term, contributing to environmental sustainability. Bio Hanferde simplifies cultivation by eliminating complex fertilizer routines and reducing water use while ensuring optimal nutrient supply. It promotes vigorous vegetative growth and enhances the development of cannabinoids, terpenes, and other active compounds during flowering. Need an alternative? Check out Sonnerde’s Bio Schwarzerde.
