- Place the slabs in your grow trays and spray down the mineral wool with nutrient solution through the pre-cut squares until saturated. Let them soak without draining for a minimum of 30 minutes.
- When you’re ready for planting, cut drainage slits in the bottom of the slabs to prevent over-watering, then place your plants’ grow blocks directly onto the pre-cut squares.
- As your fertigation system circulates nutrients and water to your plants, RedRock’s specialized wetting agent will deliver it evenly throughout your plants’ root zone.
