Thank you .I am growing in large bags .The type used for bulk animal feed .My son sowed on the ground as a school project and there was wire worm .Thats why my venture is with clay and compost sourced externally and using the large bags .The fertilizer is Chicken manure seven years old sourced from a friend .No way of checking anything scientifically so going by gut feeling and of course your advice .We will see how it goes and thanks again .Passing the time for me during this crisis .
