Ah yeh! So this is a thing! Well I kinda guessed it was but I have been a little lost and confused as I’ve previously read and been told by dude in hydro store you don’t mix organic with coco without soil, but seen there’s a product here in England called eco thrive. Basically it’s beetle poo. And they recommend adding it so coco and even sell coco with it added. There’s also a product called biosys tea which is not a tea as such but a ton of beneficial bacteria. Here’s there site https://ecothrive.co.uk/
