I must tell you that I am very satisfied with Biostimax^®. Given the weather this year with plenty of rain, heat, a dry period then again downpours, etc., my yields are really plentiful. In my area, others also have gardens and you can see an obvious difference. For example, with tomatoes: most have already been harvested, and I am still picking beautiful red fruits. Of course, I will continue using Biostimax^®.
