This is the first ever food-grade 1590 micron water crystals, a special food-grade, 100% biodegradable formula. Mixed with pure UK agricultural (white-gypsum) for ease of application.
Better than prior crystals due to smaller size as powder, making for full instant activation (Non gloopy) and added benefits of Gypsum for calcium and flocculation of soil.
Increases fertiliser/nutrient retention and reduces watering requirements.
