well at least you will get organic ferts there you will only get chem ferts elsewhere, if your going there any time soon i recomend getting the bio bizz range its the cheapest but still not to cheap after you get them all , here is what i got
you can get 1 at a time bio grow first then bio bloom for flowering and top max and there is a P/K solution too to use each can cost around €17-€20 there is another in that range called bio heaven €45 a bottle haven't used it myself but i heard some good things about it so i might get some soon
