FoxFarmCultivation Nation pH Up - Liquid Nutrient Solution Adjuster, Raises pH Levels for Hydroponic & Soil Gardens - Formulated with Potassium Hydroxide for Optimal Growth (Quart)

I have used my own pH up or down and or general hydroponics pH up or down for years.I think the GH pH up ions clash with the r.o. water ions used to mix the fox farm nutes.That the GH pH up clashes directly with the fox farm liquid nutes.Highly recommend using this and or another pH up product if your using fox farm liquid nutrients.Tiger bloom lowers your pH dramatically.Also your water must be reverse osmosis water and or filtered water to prevent the fox farm ion clashing with the water.End result = unhappy / slowly dying plant.Check your pH, ppms, ec, and water temps, always!!Do not let your ions clash, that's my best advice I can give if your using fox farm.

This is impressive stuff! You can use way less than some other brands. I only need 5 drops per gallon of acidic nutrient to bring it to the correct ph. And I have acidic water to begin with. I was using 3 whole dropperfuls of another brand! The photo shows two test tubes with my acidic well water and 4 drops of indicator each. The left one has one drop of Fox Farms pH up. The right has one drop of the first brand I bought. As you can see, more value for your money. So powerful they do suggest wearing protective gloves etc.! Highly recommend!

Does exactly what it's supposed to do. I'd suggest adding a few drops at a time as to not lower the pH too much. Aside from that, the bottle had no leakage, very easy to use, works exactly as intended.

During flowering the plant will eat the ph up. So you’ll have to use this daily unless your solution have all the right amount of nutrients for your plants.

Adjusted my PH a little at a time no harm to my plants

Too strong

Sometimes it takes a little sometimes it takes a lotAnd yes I shake my product before use but the ph fluctuates quite a bit after a couple minutes regardless don’t water until I have a stable ph for 24 hours

There was a hole in the cap.. without knowing.. shook it up.. and yeah nothing good came from that...
