Yes, I need to do the same. I KNOW that my bin is already ready to go for collecting the worm castings. No cardboard left at all or anything else I originally filled it with. Amazing how quickly the worms broke it all down and ingested it. It took a good 6 months initially. Now it's only been a little over a month. Ha! Crazy! But I have lots of garden beds that it can be used in since my yard is mostly sand and hardpan dirt. I would need a LOT more worms and bins to improve my yard soil. So it certainly won't go to waste or not be used.
I have another question ....
Can other worm species be added into the red wiggler bin? I have found a few large earth worms when I dug up a raised bed. I added them to the worm bin, but am now wondering if that was a good idea or not?
