What’s Are the Benefits of Managing pH?
They each have their pros and cons, so it’s important to figure out which one works better for you.
For hydroponic growing setups (as well as soilless growing mediums like coco coir) an optimum root zone pH is between 5.5 and 6.5. This is slightly more acidic than the optimal root pH for growing in soil.

Calibration, Storage and Cleaning Solution for pH Pens
- The pH of the water tends to go up when the water is oxygenated (for example by adding bubbles or shaking water) – this is normal.
- The pH also changes as plants use up nutrients in the water
- It’s a good idea to completely change your reservoir at least once every 1-2 weeks, especially in the flowering stage when plants are more picky. This constant renewal helps prevent a lot of pH problems as well as nutrient buildup in the reservoir.
- Test reservoir water regularly so you spot any pH problems before they damage your plants
- You just can’t beat the price! This is one of the cheapest pH pens I’ve seen.
- Actually comes with a 2-pack sample of calibration fluid, so you don’t need to buy those just to get started the first time (though you will need to get more soon). You still need to get storage solution.
- It may not have all the bells and whistles, but it will get the job done on a budget!
If pH is too high, add a tiny amount of “PH Down” solution to your reservoir (a little bit goes a long way with PH Down). Return to reservoir and check pH again in a few minutes.
If you’re new to adjusting pH, start small with pH Up and Down, and only work your way up to bigger amounts after you’ve gained some experience. Most growers will be able to figure out their personal measurements within 1-2 waterings.
