RedRock Grow Block PRO

The RedRock Grow Block PRO is designed for growers who need an extra edge in durability and performance. Crafted from high-grade expanded clay aggregate and fired above 2000°F, this 6in block provides plants with superior strength with the same pH-neutral, porous, and well-draining qualities as the standard RedRock Grow Block. With enhanced structural integrity, it resists compaction — even in intensive hydroponic environments — encouraging rapid root growth and exceptional oxygen flow. Each block is carefully dusted and rinsed so it maintains consistent EC levels and supports optimal nutrient uptake. Reusable across multiple grows, the Grow Block PRO is perfect for growers that want a reliable and efficient, eco-conscious option that helps plants thrive. For a seamless transition to high-capacity, full-cycle cultivation, consider the RedRock Grow Slab. If you want to start seeds or maintain clones and seedlings with targeted precision, try the RedRock Starter Block PRO.
