I am going for the bio bizz right now. I also like all their other products.
seriously though I have reading the tea section and I wonder what I need any store bought ferts now.
I mean guano and worm castings and spt are so cheap and easy to use. Maybe meta k? I having trouble justifying to myself why I got so many store bought nutes laying around.
for dirt I bought the foxfarm ocean forest/light warrior/extra perlite/dolomite lime mix I think a lot of people use.
So much easier to diy than hydro I am excited.
But Bio Bizz does look cool as OMRI and the UK version certified and coming straight from amsterdam. Make sure you read their feed chart. It is important. Also I dont think it starts at seed, more like clone or the third node. You need at least grow and flower at the same time
