I used a very simple/basic recipe after looking at a few sites..between 5 to 10 cups of compost in 20 litres of water with a cup or molasses...constantly agitating it for a couple of days coz we have no bubbler.. I had it in a 220 micron bubble bag so no filtering at the end.. I really need to get some bone meal or fish hydrolysate but we are limited here up the mountains...
