Rockwool | Germination Tray

Rockwool Germination Trays deliver professional-grade propagation for home gardeners and commercial growers alike. Engineered for optimal root development, these trays create the ideal environment for healthy, uniform seedlings from day one. How to Use Your Rockwool Tray: 1. Prepare the Tray – Soak rockwool cubes in pH-balanced water (5.5-6.5) for 30 minutes until fully saturated 2. Seed Placement – Insert 1-2 seeds into the pre-formed hole in each cube, approximately 5-10mm deep 3. Environment Setup – Place tray in a warm location (20-25°C) with indirect light; cover with humidity dome if available 4. Moisture Management – Mist daily to keep cubes moist but not waterlogged; rockwool should feel damp to touch 5. Germination – Seeds typically sprout within 3-10 days depending on variety 6. Transplanting – Once seedlings develop 2-4 true leaves and strong roots, transplant the entire cube directly into soil or hydroponic system Pro Tip: In UAE's climate, monitor moisture levels closely during hot months and provide shade during peak afternoon heat.
