Weed mat weight is a direct trade-off between durability and cost, and 75 GSM sits at the lighter end — genuinely effective at suppressing weeds and letting water and air through to the soil, just built with less material than our thicker options, which means a shorter expected lifespan in exchange for the lowest cost per square metre in our range.
That makes it a sensible choice for shorter-term growing needs, trial plots where you're testing a new bed or crop before committing to a permanent setup, or simply budget-conscious operations where the multi-season durability of our 100 or 120 GSM options isn't necessary. It's still a genuine woven fabric — more durable than a plastic mulching film — just the lightest tier within our weed mat range specifically.
