I did not find this product, it found me.. i got a small bottle of it for free with a order, since i did not have any other booster on hand at the time i tought why not give it a try and the results turned out to be great, in the meantime i think the formulation of this product changed, i've got a new bottle recently and the dosage is now 2 ml/l before it was 0.5 ml/l, to be honest i had the best results with that old little bottle that only lasted for two grows
