Hi jennijenjen. Did you harvest everything but worms?Did you see eggs when harvesting? I always leave a little VC from the old bin when starting anew. Also I find thick cardboard much more worm-friendly than shredded paper. All other foods are good.
I have never bought peat or coir for my worms.Thick damp cardboard, leaves or aged horse manure are excellent free bedding.

Good luck, Pete

IMO, when harvesting a bin where peat moss is used, it can be very misleading thinking that it is all VC. All the while all the peatmoss is still there. It's just hard to see because of the colour.
I also have a RM bin and this is what I did with the lid. I removed most of the material of the lid leaving only about 1/2" from the edge. I used 2 sided adh. tape to tape weed cloth (on the inside)to close the hole. This way it keeps insects in/out but still lets a lot of air movement. I use a lot of shredded newspaper in my bins and no problems in my case. Once my bin is established (after ca. 10 months with a worm population of about 1 lb.) my harvest rate is about once every 4 mths. and I get about 4-5 gal. VC. However, the worm population grew VERY slow. So, I have been separating the biggest worms out of there and breed them in a separate smaller bin.

Pete - No, I didn't see ANY eggs this last time and next time I'll be sure to save some VC for the next bin, thanks. I added alot of soaked cardboard from cereal boxes this time & it's staying moist better.

Otis - I did notice how difficult it was to tell the difference between VC and peat moss. I think I was in too much of a rush to amend my garden sand! That's a great idea with the lid, I think I can do something like that, thanks!

I was just mentioning in another post that my bedding is comprised of shredded paper some composted chicken manure and carboard. I add varying amounts of the following;

Greensand - I use as a soil amendment but I found out that it takes forever to break down in soil so I give it to the worms for grit to aid in digestion.

Alfalfa/kelp meal mix - small amounts because the alfalfa will cook the worms.

Fruits and veggies - the moisture in these foods is usually enough to keep the bedding moist as well. Foods like water melon and cantalope have a high water content as is and my worms absolutely love it!! They eat melon including the rind in only a few days. I dont get any run off but thats a good thing for me since I dont use it.

Aside from that, I mist the bed once a week if needed. My bin is an indoor one in totes...so it works pretty good for me.

Hope this helps.

Where do you purchase the greensand? I would like to find it at a store nearby. Is all greensand the same? Is there a name brand I should look for. Puting it in my vermicompost bin would be great because where ever my vermicompost goes in my yard is where I want the best bit of soil to be.

Sorry to follow up so late. I been offline for a few days. Greensand you could get under many brands I suppose. I get the Espoma brand which is pretty good IMO. I get if from home depot.
