Purchasing this product did me very well. I should also tell you that it was the first time I had purchased and used this product. There was obviously some nutrients missing, or my plants wouldn't have reacted the way they did. This concentrated formula helped accelerate rapid growth to my blooms. Bud Boom also added some kind of super steroid when I added it to my nutrient solution, therefore my plants produced 'more than usual' in the final last couple of the growth cycle. I also noticed more oil resin production in my plants when harvest time came, that was unexpected and also an extra added bonus. My thoughts would be, if your not using this product, of haven't tried it, you should, just once.
