liquid gold!!
you then dilute it 1:20 so allready I have 400 litres of liquid fertalizer ready to use on my garden!!!
they are so worth it
Make sure if you do get one- get your worms from a good quality worm farmer and get between 2,00-3,000 worms per farm

I am nearly ready to let my worms go up a level so will be able to make some worm tea with the casting soon too!!

Ebay is a great place to get second hand farms and composts cheap!!!
