Using food grade 44 gallon drums cut longways in half there is a simple system to establish a great worm farm.
Undoubtedly the most common species of worm used for composting is Eisenia fetida – the ‘Red Wiggler’ worm, also known as Red Worms, Brandling Worms, Manure Worms, and Tiger Worms (among others). This worm can vary widely in terms of coloration and size, which helps to explain why there are so many common names. This also highlights the important of using scientific names!
Composting with worm farm produce is very effective. Casting compost and compost tea from a worm farm are many times stronger than common fertilisers and need to be watered down between 4 and 10 times.
