kind of like cars Doobie, just boxes with 4 wheels.......well not really, all cars are different and although they generally all move forward and back, some do it better than others.
Or I could say, "tell that to Advanced Nutrients", lol.
I am sure you could get an equivalent "organic" nutrient with another product. I think VTM is interested in that one as it's tried and tested and works well with organic mediums. I have found it hard to actually get the nutrient over here, my bloody local grow shop didn't have any for almost 6 months. Anyway, if I find anywhere I'll be sure to let you know VTM.
