How much spent coffee grounds do you put in your compost?

I have a limitless supply from a cafe, but i’ve read coffee has some negative properties for plants, even when composted. Some sources say no more than 10% could be ok. I wonder how much other people use?

I’ll use compost only as potting mix and for raising seedlings, so I can’t risk anything negative to germination or fast seedling growth. I feel a bit worried I added coffee to my current compost bin.

I can't speak from experience, but some of the sources I have researched allow for 10 to 20 percent of a compost pile without averse effects.

Oh, for the problem of having TOO MANY coffee grounds!  I can only dream.

I've got java envy.

"The rule of no realm is mine.  But all worthy things that are in peril as the world now stands, these are my care.  And for my part, I shall not wholly fail in my task if anything that passes through this night can still grow fairer or bear fruit and flower again in days to come.  For I too am a steward.  Did you not know?"    Gandolf

About 40% of my allotment compost heap is coffee grounds and biodegradable filters! The rest being shredded straw/sawdust and lawn clippings.
