## Customer Reviews

### ⭐⭐⭐⭐⭐ Clean hydroponic plant food
*by M***N on January 13, 2019*

After using many others it was amazing to see a soluble plant food completely dissolve and result in a beautiful clear solution. Great for foliar, too; it won't clog spray bottles. Fast shipping!UPDATE: The pH buffers put the pH around mid to upper 5's. Great for hydro or soilless media, which is what this product is really intended for. If your plants are in soil you will need to always adjust UP, or consider another fertilizer.

### ⭐⭐⭐⭐⭐ Results for pennies on the dollar
*by D***. on October 24, 2018*

If you like overpaying for nutrients then don’t buy this product. This is hands down the best nutes you can buy because the quality is still there and it will last you like 10,000 gallons of watering

### ⭐⭐⭐ failed . sent me 15-5-15
*by H***! on September 30, 2020*

was looking forward to see how peters compared to jacks. Sent me 15-5-15 instead
