i heard that i have to add microherd so that biobizz ( it is organic nutrient ) could work .

is biobizz really useless with peatmoss or cocopeat unless there is microherd ?

only is humus enough for adding microherd to soilless mix ?

there is humus here but i cant find worm
casts here.

could i use humus in instead of worm casts ?

i can make this soilless compost :

50% peatmoss ,
30% perlite
20% humus ( or wormcast if i can find )

does has that mix microherd and would it work with biobizz organic nutes ?
