hi

i tried to grow a mushroom growing kit (unsuccesfully)  that i picked up half a while back and i was just wondering if the stuff that was left over in the box would be ok to go in my compost bin?

You can use it straight in the garden but composting is also okay.  Brassicas LOVE it incidentally

Don't see why not, and if you put it on your compost heap, I bet you'll get loads of mushrooms!!!!!
