I use Roots Excelorator by House and Garden in DWC, Ebb and Flow, and in my aerocloner. It dissolves totally in water and doesn't leave residue like the powder forms of beneficials i.e. Great White, Tarantula, piranah, Gh Subcultures.
I also feed less than recommended doses. I have seen my ppm drop from 820 to 700 over night after an innoculation. The plants just eat and eat. Do not use h2o2 with bene's
I also use Hygrozyme Aquashield and sugars in flower. Aquashield is an organic compost catalyst that the bene's feed of off, they also feed of the sugars (bud candy, sweet) shit like that.
