by: viagrow

Item VPTK4
Our Price: $12.99

The Viagrow® natural pH control kit comes complete with pH Up & down adjusting powder crystals and is formulated using the highest food grade quality and includes a broad range pH test kit which will indicate the pH value of your nutrient solution. While the pH down powder contains food grade citric acid and is safe for all food crops, the pH Up powder contains food grade potassium bicarbonate and is safe for all food crops. The Viagrow® pH Up & down are highly concentrated so less is needed for use as compared to most brands.  Viagrow® pH Up & down can be used in all growing mediums – Soil, soilless, hydroponics, or to adjust a foliar application.  Maintaining a proper pH is an important part of growing healthy plants and your broad range pH test kit will measure pH as low as 4 and as high as a value of 10. To grow the most vigorous plants maintain a slightly acidic pH in your choice of growing media, It is recommended that the pH for most crops fall between 5.5 and 6.5. Use moderately. Add a small amount of the pH adjusting crystals, mix thoroughly and then test the pH. Repeat application and test again until appropriate pH level is achieved.

  • Does this work with fish tanks too?
    No. Fish Tanks require different PH testing tools
  • Is this pH solution organic
    Though this pH Solution is not organic, it should not effect your plants as long as you flush them pre-harvest. If you are interested in a more organic based pH solution, try the Viagrow™ Natural pH-Up and pH Down Adjusting Solution, 1 Lb.
  • Your instructions here say Fill the included test tube about halfway with nutrient solution, then add a few drops of the pH test indicator The instructions that come with kit say Add 4 drops to 2 oz clear water. Does it matter how many drops in how much water, or whether its clear water or nutrient solution
    Hello Dexter, Thank you for your inquiry. Our pH Test Kit and pH Adjusting Kit is an inexpensive and accurate method of checking and adjusting your pH. We are aware that the color chart and package instructions vary slightly we apologize for any confusion that may have caused. The volume of water does matter as long as it is not over 2 ounces. Add a few drops 3-5 of the testing reagent to the solution to be tested less than 2 oz and it will provide accurate test results. As far as the color of the water to be tested goes clear or with nutrient solution, as long as the starting color is transparent and not so heavily saturated the test will work. If the solution to be tested has such a heavy color saturation that it will be impossible to discern the color after the reagent is added then you will need a digital meter to accurately ascertain the pH. If you have any further questions then please let us know. Kindest Regards, Atlantis Hydroponics
