Pretty much aye i just use there all mix compost some seedling compost on top for the seedling stage and there veg and bloom nutes and top max sometimes but i will say you need some source of organic calmag in Scotland our waters too soft so idk what your waters like but depends u may need to add a lil of that if your waters soft like here also if you got anything thats a really heavy feeder biobizz is on the lighter side of things so if i run anything like that i also give it a wee dose of seaweed based fertiliser to supplement it now and then but for most things bio bizz alone is fine
