Dont know if its been mentioned already but thought i'd post anyway.
With a sheet of newspaper (sun,mirror sized) fold in half lengthways so you have a long thick strip. Grab a pint glass and wrap the paper around the top of the glass leaving roughly a 2 inch overhang. Next push the overhanging paper into the glass and press firmly around the rim. Then take your paper off the glass and push the solid end of the glass down through the pot which should then close the paper at the bottom into a perfect seal.
Ideal for any veg and the paper pot can be put straight into the ground and will compost down. No need to ever purchase pots again and a great way to keep the kids busy
