DIY potting compost

My mix for both potting on and filling baskets is made up by mixing 12lts. of compost bought from asda, 4lts. of compost bought from home bargains, 6 lts. of soil/sand mix and 4lts. of perlite 80mg of chicken manure and 80mg of blood fish and bone, all well mixed then soaked and left overnight usually used the following day, I was hoping that I could avoid purchasing compost but there is no way I could make enough garden compost just now, I had added a lot of compostable waste into a bed where I am trying a form of hugelkulture plus the winter has been to cold and wet
Well for me to go out and turn it(rolleyes)
