At 256 GSM, this fabric is thick enough to hold structural shape under a fully saturated soil load, withstand repeated handling and transport without tearing, and survive multiple wash cycles between runs. The pore structure stays consistent across the entire container wall — which matters for even air exchange and reliable drainage. Many bags sold at lower price points use 100–150 GSM material that stretches out of shape, tears at the handles, and loses structural integrity within a season. The 256 GSM nonwoven used here is purpose-built for growing operations that take the work seriously.
