I'm going to be of digging up another 5 beds before winter (starting now) and I want to make sure they don't get any weed growth. I'd like to buy 100m of 1.5m ground cover and I see you can get the 50gsm fabric or the more heavyweight 100gsm tarpaulin-type material. Any thoughts on how effective the 50gsm fabric is at keeping out light and stopping the weeds?? Big difference in cost. If anyone has any recommendations on suppliers it would be great. Thanks all.
