I start mine off beginning of jan on a radiator (it works for me ), first fill your pot with compost , wet it, add the seed, compost on top then I put cling-film on top...then as soon as I see owt sprouting off comes the cling-film and the little bugger roughs it out anywhere I can put it in the house. ive had some good results this way. some seeds take a lot longer than others so be prepared to wait..
