high,
i kno this from mulch....cheap mulch is often acidic , which can wash out cadmium...but if to much molasses has same effect dunno...but never say never...
i dont use
biobizz anymore...i use blackstrab molasses,EM-a,ACT and supersoil ,better to say superrich really healthy living soil...either like 'no till'method but in no tilling you use cover crops too which make nutrition more available etc
.. .....i would say the best product from bb is fishmix...
in most growshops it is the only line up which can produce a nice product , instead of chem-stuff with focus on yield...indeed either the only organic product line in most growshops around my area in ger..
but i got to say this bio heaven is to expensive...bio heaven compared with EM-A or ACT is a joke sorry...
and EM-a costs 5 liter round about 19 euro and you can use it for much more in growing...
