I would like to know if a bucket that I want to use to recycle my kitchen scraps need holes or a tap for the tea to come out?
If you want to harvest and use the worm tea that is produced in your worm farm than you should either drill holes in the bottom of your worm bin or install a tap to it. This is actually not that difficult and you might get a tap at your nearest nursery or plastic retailer. Go to the site map of www.worm-composting-help.com You will find a few pages about worm tea as well as instructions about setting up different kinds of worm farms.
I am sure you will find there the information that you are looking for.
