I took a chance on the product to hurry up the growth of my brussle sprouts because they were growing to slow and after more than two weeks with not much noticeable change. On the other hand my green beans are doing good. The reason for buying the product was mainly for the brussle sprouts. Maybe my soil isn't good with the product I am not sure just my opionon. I cann't justify the cost for the results. I am happy with the seller with the fast shipping and great packaging though. This is why I wrote what I did. I try to be positive but in this case hard to be. Maybe I received a bad batch not sure. Thank you for reading my review.
