Yesterday we took a step towards fulfilling our Worm Dream to one day have an abundant healthy population of composting worms at Pixxe, and to help people compost their own organic waste in their own homes using worms.
The design we are working on is the stackable worm bin. We discovered that from a single pallet we can make three boxes and a base. The boxes will be approximately 40 cm x 30 cm, with a depth of either 12,5-13 cm or 21 cm. We’ll start with 12,5 cm.
Our first batch of worms are living in this 20 liter black bucket. Dimensions: 35 cm diameter, 25 cm deep. First, the bedding: brown leaves, damp cardboard, newspaper, paper, straw–all of these ripped, shredded, or chopped, plus some wood chips. To this approximately 3 cups of water were added as well as 1 handful of sand, 1 handful of good soil from the garden, and 1 handful of crushed egg shells. Mix well. The bucket, about 80% full, was then left for about two days to let the water soak in. The consistency of the bedding was like a damp sponge, as is often recommended.
Into the bucket went the 500 red composting worms (dżdżownice kaliforniskie, Eisenia fetida) along with the bedding in which they were sent, which was quite decomposed. The worms quickly scurried down and out of sight. Next the bucket was topped off with a 10cm layer of leaves and straw. I decided not to drill holes in the bucket because it has quite a bit of surface area for “breathing” and the bedding itself has quite a bit of air space. So, I will need to check frequently to make sure it’s getting enough air. The bucket is in the bathroom, where it’s nice and toasty.The worms were left alone for about 3 days to get used to their new home, and today we fed them 250g of finely chopped and rotting pears, apples, blueberries, raspberries, cabbage, kale, lettuce, zuchinni, coffee grounds, banana peels, egg shells. YUM! Go worm, go! We put the food in one half of the bucket, buried about half way. They looked really great in there wiggling around. When the stackable bin is finished, I’ll post some more photos! Thanks MH for taking photos!
