KelpMax (from Ecklonia maxima) is only available via Ray (in the US).
There is a study to compare six different seaweed extracts (Stirk and van Staden 1997. J. of Applied Phycology 8: 503-508). It used Mung Beans to measure the root production. KelpMax does have the highest root production (when it was used at a really high concentration). But at the concentration we use (2 tsp/gallon = 0.26% v/v), the difference among products were relatively small. There was no statistics, but KelpMax and Maxicrop were similar at 0.2-1%, and they appeared to be better than others. But this experiment is just one side of the plant growth regulators, and other aspects could differ among products. For some reason, the authors of the study made the concluding statement that the levels of auxin- and cytokinin-activities were similar among different products.
