## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Expensive but works
  

*by J***W on Reviewed in the United States on March 3, 2019*

I did a side by side grow, plants with bloom booster were three times bigger after 2-3 days. I had another brand of pk booster, it worked pretty good also but not as good as sonic bloom. Im going to add some B1 next time to see if that will close the gap a little. It's a little pricey, but it works, I can probably duplicate it for cheaper, but then there is more time involved. It is a good product, you won't be disappointed

### ⭐⭐⭐ 







  
  
    So far so good, will update after growth
  

*by T***E on Reviewed in the United States on August 2, 2021*

(Currently using, will update after grow season.)Positives are; it can be used without fear of fertilizer burn.Negatives; measurements are given for 5gal mixes so there is some quick math needed for 1gal batch.

### ⭐⭐⭐⭐⭐ 







  
  
    It's an awesome product
  

*by R***N on Reviewed in the United States on October 9, 2021*

It's alot cheaper in your local stores. Problem was I couldn't find it locally.  It's an awesome product. It makes your buds bigger amongst other things. If you're growing marijuana you need this!!!
