Ahh biobizz, i remember now, found a guy who totally bashed Biobizz, i have always loved it but understand what he was saying, quite imbalanced. I never used topmax and got the fish mix instead, i alternate that with my grow and seems to work a lot better now. I dont subscribe to pk boosts unfortunatly, the biobizz bloom seems boost enough on its own.
Personally i liked the look of Sensi's iguana juice but i need more info before i swap of the biobizz but should others recomend better and can give good reason and its cheap then i might just swap my flowering bloom for another make, i still love the biobizz grow and fish-mix though. The Foliar seems to get very good results but i dont foliar feed unfortunatly othrewise id give you more feedback on that.
Maybe the sensible grower would change to a more controllable ferts, seen good results with Ionics and similar, who knows what the future holds, i really loved the Biobizz but people are telling me to change! Peace
