Germination Tips for UAE Climate

Pre-soak cubes in pH 5.5 water for at least 30–60 minutes before use. Shake out excess water gently — do not wring. In UAE summer (40°C+), germinate in an air-conditioned space or shaded indoor area for best results. Most seeds germinate best between 22–26°C. A plastic humidity dome placed over the cubes helps retain moisture and dramatically speeds germination in the dry UAE environment. Once roots emerge from the base of the cube (usually 7–14 days), your seedlings are ready to transplant.

How to Use Rockwool Cubes Step-by-Step

1. Soak cubes in pH 5.5 adjusted water for 30–60 minutes
2. Place cubes in a humidity tray or propagation dome
3. Insert 1–2 seeds per cube, 5mm deep into the pre-formed hole
4. Keep cubes moist (not soaking wet) and maintain 22–26°C temperature
5. Provide mild light (18 hours/day recommended) once seedlings emerge
6. Transplant to your NFT, DWC, or Dutch Bucket system when roots appear at cube base
