I was mixing some super soil up today,old and new soil,fish,blood and bone,ewc,bat guano,beetle fras,bio buzz pre-mix and perlite.anyway when I got to the third 15litre pot of used soil,I noticed a bad smell.like shitty bad.i chucked it outside,decided not to use this one.so I was thinking,anyone else noticed similar?and would is have been ok to use still?also what you guys think of bio buzz pre mix.its got everything in except ewc.rock,plant,bone beneficials.so thought id give it a shot.ive got 2 trash can's full,cooking up with all the above.just gotta add the perlite,and more ewc and frass.last mix worked out great with less goodies so,should be real nice..i hope.
