I ran a test grow with Dakine 420 nutrients and was pleasantly surprised. I judge nutrients by the health and vigor of a plant. Dakine has the right ratio of nutrients in their formula. I noticed fat and healthy stalks from the three varieties I tested them on. I have decided to run a second grow with 4 plants in a more harsh environment. If they do well there, which I think they will, then I will bring their product into my main garden.
