I would say that sensi ph perfect is superior to biobizz in terms of what it offers, slightly more expensive but not much. Athena is another line that is marketed for hydro but you can use in soil without any problem, its one of the best lines but its also expensive.
The major difference between biobizz and sensi ph perfect is that you dont need to flush with biobizz and you will get a more organic taste, to me it tastes more hashy and sometimes more earthy too, depends on the strain. But hey, not all the cannabis cup winners are grown organic, its a matter of preference. In terms of performance sensi ph wins, but if you wanna go organic you need to go for biobizz. There are other options too, I just chose the cheapest ones without sacrificing your plants needs.
