i love organics and have found that the BioBizz line is great and effective.
the suggestions on the bottle are something like 5ml per liter of water. i just use 10ML of total solution per gallon of water and have found at that rate that the PH will become optimum. so if im using BioGrow and Algamic i'll add 5ml each per gallon of water, then the next feeding would be something like bioheaven + Grow + algamic and i can confiently say that i get great results.
they'er easy organics. i used to use EarthJuice and i found those products to be a big pain in the ass. first you have to set up a recirculating res just to activate them then you have to poor the shit thru a strainer before you can even water your plants.!!!! BIG PAIN IN THE ASS!!
but with BB i'm happy cuz they have the SKAL and the EKO certification and they'er easy
