Do you need to add water to the Subpod at all, or just water the garden bed as usual?
You do not need to add extra water to the Subpod, as there should be plenty of liquid coming from your food scraps. It's important to make sure the worm blanket is kept moist though.
To test if the worm blanket has enough moisture…. Squeeze the blanket. Only a few drops should come out.
If no water drips out you will need to soak the blanket in a bucket of water
Some people have actually found that they don’t need to water their garden as much due to the moisture coming from the food scraps.
