advanced nutrients tarantula,vodoo or piranha for addind micro herd

i will grow in coco (hand watering ) with 20%worm casts and i'll only using biobizz nutes(bloom,grow,topmax)).there is already microherd in wormcasts.
i think ad tarantula may help to increase amount of microbes.but i dont know.

tarantula,vodoo or piranha,which is the best to add micro herd ?

what is ur opinions ?

isnt there anyone who used them ?

i cant buy all of them.
which one should i buy to add microherd and microactivity that would break my organic nutes down ?

Thanks

use tarantula first for veg and first 2 weeeks of flowering, then add piranha which protects tarantula microbials and last add voodoo- hope i helped, i only use tarantula
