If you are interested in making fruit wines at home, or brewing up a small batch of something, then a mini primary fermenter may be a great thing to invest in. They are so easy to make and you can use any food grade plastic container.
This is microfarming at its best! Instead of tossing those old worn out Toms, transform them into hanging planters! They provide the perfect amount of root space for a small plant and just enough head space to give them room to grow.
