I've just bought 2 bags of Miracle Grow Moisture Control compost. When loading it into the car one of them seems a little light, but I didn't really think much of it. There weren't any tears in the bag so it hadn't lost content.
When I opened the lighter one it was bone dry with almost solid chunks in it. It did break down with a bit of persuasion but I'm wondering if there will be any life in whatever is used for the moisture control element.
I'm wondering if it was left over stock from last year although the other bag is OK.
