PRO-MIX BK

PRO-MIX BK is a professional-grade substrate with low compaction and high aeration that’s made for growers looking for a medium that delivers consistency, control, and vigorous plant growth. With a higher percentage of coarse peat moss and perlite, it provides excellent drainage and moderate water retention — making it perfect for crops sensitive to overwatering. Its structure allows for ideal root zone oxygenation, helping plants develop strong, healthy roots and max nutrient uptake. It’s especially beneficial for larger containers and automated systems that require dependable flow and root stability. It doesn’t contain added fertilizers — but it does give you a clean slate for customizing your nutrient regime. For a similar mix with enhanced root support, check out PRO-MIX BG AGTIV REACH. If you need increased capacity to retain moisture with balanced aeration, the PRO-MIX BX is a soli option.
