How to Use Rockwool Cubes in UAE Hydroponics

Soak cubes in pH 5.5 water for 1 hour before use. Press seeds 5mm deep into the pre-made hole. Keep moist (not saturated) at 22–26°C until germination. Transfer to your hydroponic system once roots emerge from the base of the cube (7–14 days for most crops).

In UAE’s extreme summer heat (40°C+), germinate in an air-conditioned room or shaded indoor area. A humidity dome dramatically improves germination speed and success rates in the dry UAE climate. Maintain pH 5.5–6.0 throughout the germination phase for best results.
