does it say anywhere what's actually in it , what microbes , what's the source of nutrients
buying lab produced microbes are generally a little more expensive but we are also finding out microbes produced in a lab might not be as resilient as the same found naturally in nature , or in your own backyard or compost bin / worm farm
in fact using home made worm castings or compost full of indigenous microbes & nutrients would achieve the same thing if not something better
imho the thinking " canna is a weed " is straight up wrong , based on that thinking i could say canna is a rose or a fern
i think our definition of a weed is only " a plant in the wrong spot " , weeds are part of succession
"On a bare soil substrate the process of ecological succession starts with the colonialization of the soil by one or
more low order species (typically weeds, sedges and annual grasses, and mainly bacteria) and will progressively
move towards increasing numbers of higher order species (perennial grasses, shrubs and trees "
" Pioneer plants—what we call weeds—are those species that can rapidly cover bare soil and begin performing one
or more of the following vital ecological functions: Protect the soil from erosion. Replenish organic matter, and feed
and restore soil life "
