PNC Hydrohum Tablets - Water Retention + Nutrition | 10 Pack

PNC Hydrohum Tablets

€9.90 €7.88

Water Retention + Nutrition | 10 Pack

Combines two technologies: a biodegradable hydrogel reservoir that prevents drought, and a slow-release organic-mineral fertilizer that feeds plants for months.

Soil Health in One Tablet HUMKO PNC Hydrohum combines two technologies: a biodegradable hydrogel reservoir that prevents drought, and a slow-release organic-mineral fertilizer that feeds plants for months. It's the ultimate convenience for busy gardeners and professionals. Dual-Action Technology 1. Ionic Pump Hydration The tablet contains hydrogel (20-80% concentration) that swells to hold water and dissolved nutrients. As the soil dries, it releases moisture steadily—no more wilting between waterings. 2. Controlled Nutrient Release Essential NPK plus micronutrients are embedded in a coating that responds to soil moisture and temperature. This synchronizes feeding with plant growth cycles. Key Benefits Easy Placement: Simply insert the tablet 10cm deep near the root ball 3-6 Month Feeding: One application per growing season Drought Protection: Water reservoir prevents stress Eco-Friendly: Biodegradable, no plastic residue Precision Dosing: 1 tablet = 2-3L substrate Ideal For Balcony plants and hanging baskets Potted vegetables and herbs Container ornamentals Young trees and shrubs at planting Urban green infrastructure (green walls, rooftop gardens) Application Dig a small hole 10cm deep adjacent to the root system. Place one tablet, backfill with soil, and water thoroughly. The tablet will activate and begin its dual action within hours. Dosage: 1 tablet per 2-3 liters of substrate. For larger containers (>10L), use multiple tablets spaced evenly.
