Crazy Hills produces organic hydroponic nutrients, biostimulants, microbes, and soil products for indoor growing, using plant-based ingredients and simplified feeding systems designed for natural cultivation.
Crazy Hills is a plant nutrition brand focused on organic fertilisers, biostimulants, and microbial products for indoor growing and natural cultivation. The company develops plant-based nutrient formulas designed to support plant growth while emphasizing simple feeding systems and natural ingredients.
The brand builds its approach around organic inputs sourced from natural materials. According to the company, its products are made with vegan-friendly ingredients and contain no animal-derived materials. These inputs are used to create nutrient formulas intended to support plant development while maintaining clean cultivation practices.
Crazy Hills also emphasizes small-batch production. The company describes its nutrients as micro-batch crafted, using fresh organic inputs to produce concentrated formulas for growers who prefer natural cultivation methods.
The brand traces its roots back to early grow shop culture in the Netherlands, where the founder’s family operated one of the early grow stores. This background shaped the company’s focus on cultivation knowledge and plant-focused product development.
The Crazy Hills product range includes organic fertilisers, plant boosters, microbial products, and soil substrates designed to support plants throughout the cultivation cycle.
The nutrient system is built around a small number of products that can be combined into a complete feeding program. Examples from the lineup include:
Many of these formulations contain ingredients such as seaweed extracts, amino acids, humic and fulvic acids, vitamins, and beneficial microbes that help support plant growth and nutrient availability.
A defining feature of the Crazy Hills system is its simplified nutrient structure. Instead of large multi-bottle feeding programs, the brand focuses on a smaller set of concentrated products designed to work together across the full cultivation cycle.
The products are designed to be compatible with several growing methods, including soil, coco-based substrates, compost teas, and some hydroponic setups.
Crazy Hills positions its nutrient system around natural plant nutrition, simple feeding programs, and organic ingredients. Through a combination of organic fertilisers, microbial products, and biostimulants, the brand provides growers with tools for managing plant growth, root health, and flowering within organic indoor growing systems.
