When composting grass cuttings, you need to add plenty of carbon-rich materials such as shredded dry leaves or cardboard but if you don't have that sort of waste, Complete Rot is the answer.
Made from restructured organic waste material, these little pellets of natural enzymes and free carbon balance out the high levels of nitrogen that grass mowings contain.
Complete Rot for Grass can be used with any composter, but if used on an open compost heap, we'd recommend covering it to keep out the rain.
