I have recently been doing some light research on plant hormones. This research was tipped off by trying to figure out the purpose and content of ADA's Green Gain. From what I can determine, Green Gain is a solution of nutrients and a hormone called Cytokinin, which serves the purpose of of promoting cell division in plants. It is recommended that the green gain be added after trimming to prevent plants from experiencing shock. This seems to make sense but some people claim green gain is just high priced snake oil.
My questions: is there an appreciable effect of green gain on aquatic plants? Does anyone know what kind of cytokinin is used in green gain? Are there potentially other plant hormones that would benefit aquatic plant growth?
