If ya add the watermelon, add some more Browns and then you can add the molasses at about a teaspoon of gallon will be fine.I have a 42-43 gal compost bin it spins it 2 separate chambers. It's not ready yet I put any, and everything I can in it. I need to cut some thing up smaller like watermelon rind I can hear still banging around lol. I was thinking of putting molasses in there too.
After about week 3-4 I'm always ready to start more just no room
