Not too wet
I've been juicing fruits and vegetables everyday and since then, I've been tossing all of the left over juice pulp in y compost This is probably giving my compost too much nitrogen all at once, so it started getting soggy and matted, and once that happens in your compost for whatever reason, it will start to stink a little. It's because anaerobic bacteria; the bad guys will decompose matter where there is no oxygen and high moisture. They give off a bad smell and slimy green stuff.
To get the good guys back in, you should introduce oxygen back to the mix. This could easily be done by either laying out the compost for a while, and mixing it back together. Compost does happen fast in Kuwait, so do take advantage of the hot summer.
