Description

Stabilize your nutrient pH with General Hydroponics® pH Up and pH Down. pH is important because it affects availability and absorption of several of the 16 atomic elements needed for plant growth. Maximum absorption of these elements is found at pH readings 5.5 to 6.5. When pH falls below this range many of the macroelements (NPK) have less availability, and absorption of the micronutrients can reach toxic levels. pH Up is a base solution formulated with potassium hydroxide and potassium carbonate. Add a little at a time when your nutrient pH is too low in order to raise it to the proper level. pH Down is an acid formulation that uses phosphoric acid to lower the pH. Always start out with one milliliter of pH Up/Down per gallon. Wait 15 To 30 minutes, and test your water again. You will usually only need 1 to 2 ml of pH Up/Down per gallon of water. You may need additional pH Up/Down if you have hard water.

  • Works Well
Size: 1 quart Style: pH Down
As a newbie, I had no idea how high the PH of our water was. I knew the soil around my plants was showing a higher PH than I wanted, and I was just contributing to the problem each time I watered them. I use this to treat my water before watering the plants, and it’s working very well.

  • Good buy
Size: 1 gal Style: pH Up
The instructions clearing details how to use. Pretty good value vs buying smaller sizes. Since using this product my plants are thriving. The liquid is the color it should be. It’s also as thick as should be and doesn’t look diluted.

Been using GH pH up for awhile. Always buy on here cause the price is right and don't have to drive over an hour to the closest hydro store.
