Good for you! Both for bringing the worms home and for for supporting the ecohouse by hiring them to do the set up.

You'll find that quite a bit of leachate drains, or at least I did. I had a shallow tray under my first bin. The first winter indoors I didn't check it very often and have the stains on a corner of the hardwood floor to prove it.

With your set up it shouldn't be a problem. Just keep the container with the worms in it from sitting in the liquid - you want the worms' environment moist but not saturated. just how much fluid you get in the bottm container will vary with how much wet stuff (veggies, etc.) and how much dry stuff (shredded paper) you're putting in.

I suggest checking once a week at first to see how much fluid is collecting. If there's not much, you can check every 2-4 weeks.

Remember the the liquid is a great plant fertilizer. I suggest diluting it before addin it to house plants. It may have been coincidence, but I think I killed a plant once putting it on full strength. Diluted, my house plant love it.

The red wigglers for composting aren't usually used for fishing, although I guess you could. They are small compared to the earth worms people think of when they hear the word "worm". Sounds like you have the right critters.

Your bin will get established quickly. I'm assuming you got good advise about what to add and what not to add. Add new material at one end of the bin at first. When that gets fairly full, start adding it predominately at the other. This allows the worms to continue working on the food at one end and gradually migrate to the other as that's digested.

Hope this helps,

Jake

Just an update:

The worm bin seems to be going fine. So far we have added 3 pockets of food. The first was a chopped lettuce/asparagus/carrot gratings combination. They liked it OK. The second was a chopped pear/cauliflower combo. They LOVED that one. They were just in a huge mass all over it. The third is a turnip/potato peel/apple peel combo. It's getting a lukewarm reception from the wormies.

All in all, the bin is going well. We've had no escapees. It got what I thought was a bit too damp, so I left the lid off for the day until the top layer was a bit dryer and have had no problems since.

It's only been a few weeks, but I am anxious to see how things are turning out underneath it all.
