Growgreen Grow Blocks are 5 kg compressed coco peat blocks made from dried and processed coconut husk fibers. Designed for efficient transport and storage, these blocks rapidly expand when hydrated—just one block mixed with approximately 25 litres of water yields 60 to 75 litres of high-quality growing medium. The reconstituted coco peat offers excellent water retention, aeration, and root support, making it ideal for seed starting, potting mixes, and hydroponic systems. Sustainable and easy to use, Grow Blocks are a reliable solution for both home and professional growers.
