Buy Potassium Polyacrylate, hydrogel. The hydrogel is applied for water and nutrient retention in soils, improving water management and plant growth, acting as a water reservoir and releasing it according to the plants' needs.
Reduces watering frequency by up to 50% y reduces the need for fertilisers. Environmentally safe and biodegradable.
After 50 wet-dry cycles the absorption capacity of this water retainer is superior to the 80%.

Fine grain: Dry size between 0.8 and 1.2mm.
Medium grain: Dry size between 1.2 and 1.8mm. Hydrated they have an irregular size in crystals of 10-20mm.
You can select either a dry grain size of 0.8-1.2mm or 1.2-2mm. The technical characteristics of both are the same, the smaller grain size is intended for smaller plants or seedlings.
