its from house and garden, i blv
also you run it with the nutes. it supposedly helps so much that you dont have to flush as much, but you need to use it through the whole cycle of the plants meaning if you start it with a 4 week old plant or older, it may flush out the needed nutes aka more harm then help aka spending money on nutes to get rid of nutes you are also spending money on. lol (yea im high
)
hope this helps
