Reiziger Holland

Reiziger is a hydroponics and plant nutrition company rooted in Dutch cultivation heritage and commercializing fertilizers, boosters, and substrates for precision growers. The brand traces its origins to the 1980s and positions its products as ultrapure Dutch formulations developed from recipes associated with the Seed Bank of Holland. Its commercial lineup includes Coco Food A&B, Root Booster, Grow Booster, Bloom Minerals, Bud Booster, and coco coir pith for use across hydroponic, coco, and soil-based cultivation systems. Reiziger appears to be an active private company focused on horticulture and cannabis-adjacent cultivation supplies rather than human healthcare, biotech, or pharmaceutical therapeutics.
