FOLLOWIN pH Up and Down Control Kit (9oz+9oz), Hydroponics pH Tester Calibration Adjuster Buffer Solution Combo for Soil Gardening Plants Pool A Balanced Nutrient

This product works well. It adjust the pH of any water and helps growing strong plants.

Use every other day and could not produce quality plants without it. Easy to use and works perfect

An affordable ph up and down control kit

Works well. 4 stars because there is no safety data sheet online for this brand.

I’ve been using this product for a while. I love it. I use 2 mL at a time and 3 gallons. It gives me instant results. I can adjust to get it down to 6.5 with no problem. Thank you. Excellent product.

Worst ph balancer ever!! Takes way too much to go down 1.0 ph. Absolute junk

Good stuff works great

I’m reading this at three out of five stars not because it didn’t work, but because it required a lot more solution to balance my tapwater compared to other brands. I almost had to use twice as much of this pH up compared to the general hydroponics, but can’t attest to the pH down as I never needed to use it. The indicator solution worked well, the solution actually worked and adjusted my water, I just burned through the bottle way faster than I should have. Going forward I’ll stick with general hydroponics but this would work in a pinch!

works well
