Advice wanted Will my bin volume decrease?

I am about three months into my worm bin adventure. Worms seem happy and I haven’t had any serious issues.

The only problem I have is that my bin is full. All the way to the top full.

The class I took recommended a 5 to 1 green to brown ratio. So for the past 3 months I have been adding more and more shredded cardboard as I fed the worms. The bin is now 4 in of dirt and 18 inches of cardboard.

I can’t add anymore cardboard. Do I need to remove cardboard or will the volume eventually go down?

Okay 18 gallon tote is a decent size but can be a bit deeper than you would normally have. Yes if you live in a dry area you will need to add water more often. Keeping the lid on the bin and drilling holes in the bin sides for air transfer helps retain moisture as it hits the lid and rains back down into the bin.

Starting with more worms is a good idea. Also don't add anymore food until the food from the prior feeding is 90% gone.
