New vermicompost turned wet
I have a fairly new "Worm Factory 360" that I'm running in my kitchen. I have 2 issues:
1) It recently turned pretty wet
2) My family creates too much waste!
I got it at the beginning of August, set it up according to instructions and added about a pound of red wigglers. I was going on vacation for 2 weeks right after that, so I added a couple pounds of watermelon rind and some eggshells and coffee grounds.
I came back in 2 weeks to find the watermelon rind completely processed and the worms very actively moving around. My family eats lots of watermelon, so I keep having a lot of it to feed the worms. I also read that its one of their favorite foods. So feeling I may have underfed them a bit (and having lots of watermelon rind around) I proceeded to feed them about an inch layer of watermelon rind across the top of the bin. I also added some torn up paper towels, more coffee grounds and some various other scraps. After about a week I could see they were making progress on the watermelon - but now the bottom of the bin has gotten pretty wet. The worm factory has a drain - it started draining about 1/3 to 1/2 cup a day of dark brown liquid.
The worms don't seem to mind it though. If you dig up the bedding it does feel a bit too wet but they are still down there in large numbers.
So I read up and over the last few days I added a lot of shredded newspaper. I think I've got it under control though haven't reversed it yet, and the amount draining is going down.
Just today I fed again, this time adding (again) lots of watermelon rind, some limp lettuce, a few overripe nectarines, some corn cob peels, egshells and a bunch of coffee grounds. I feel I have overfed again, but we just create too much food. In fact I've got a big bag of corn peels that I didn't use, and more watermelon in the fridge waiting to be eaten! Freezing the scraps won't help because it will just accumulate quicker than I can use it!
Would it help to add more worms? Or should I get another bin? Or both? If the wetness didn't seem to be bothering the worms, do you think I caught this in time? I've also been told to use coffee grounds in moderation, but I'm not sure what is moderation. I go through about a pound a week of dark roast coffee beans, which I ground fine for espresso. Is that too much to feed one worm factory?
Any advice or thoughts would be appreciated!
Oh ps: we have definitely had a big increase in fruit flies due to the bins, and overfeeding probably makes that worse. But that isn't a big deal. I haven't notice any other pest problems yet.
