RedRock Blocks stone wool blocks， slabs， and plugs offer cultivators， propagators， and commercial growers the opportunity to grow more while using less: less water， less plant nutrients， and less growing space. RedRock rockwool ensures uniform movement of water and nutrients throughout the plug， block， or slab. Our products will wet up and dry back with predictability so growers can steer crops further than ever before. New tooling and technology blend horizontal and vertical fibers for the most homogenous and predictable water transport to date. The little things make all the difference. RedRock blocks are tightly wrapped in a co-extruded film that offers a white exterior and black-out interior. WHITE ensures a cool root zone， while BLACK keeps light and algae off rockwool， even around the outer perimeter. This recipe ensures better water management and less evaporation.
