Cultilene Exact Air is a rockwool slab that gives growers max oxygen availability in the root zone without sacrificing structure or consistency. With a unique fiber orientation that boosts air content and gives roots plenty of room to breathe, it’s ideal for fast-growing, high-yielding cultivars. Its structure is perfect for aggressive feeding schedules and quick irrigation adjustments — with a uniformity across the slab that ensures even root development and reduces the risk of waterlogging, especially in high-density setups. Thanks to its improved drainage and rapid dry-back, Exact Air helps you control your crop with precision. If you’re looking for a slab with a slightly wetter base, try Exact Flora. For those working with larger plants that need strong structural support, Exxellent delivers robust performance throughout the entire grow cycle.
