Neither, I have used both.
Fox Farm is ok, but too expensive.
Bio Bizz-who knows what is in that stuff with all the owner changes. I had only 1 run with it-not happy.
However, there is a new simple organic game in town. Pura Vida from
Technaflora. This is simple, not expensive and works better than either of those two. 15ml of grow during
veg per week, 15ml of bloom during flower. Add 10ml of
Liquid Karma and some
Cal-mag and you are set. Stuff is the best I have seen since Metanaturals went away.
