  • Amazing product
Works really well for all your indoor growing needs.easy too use when treating your water.there really big bottles that'll last a while and they came early.

  • Good value
This combo is all you need to regulate PH, and it does it fast. It only takes a few drops to bring the PH up or down. So add a little, test PH, add a little, test PH until you get the desired PH. For how little I use of this to get the perfect PH, these bottles should last a long time. Very happy with this purchase. ... show more

  • Works great.
Works great. I started dabbling in hydroponics during the COVID pandemic, and bought this on Sept 2023 to adjust pH of my nutrient solution. Recommended to recreational hydroponics beginners such as myself. Color coding helps to avoid mistakes, and the color quickly disappears when mixed as I do not need a lot to bring each batch of nutrient solution to the desired pH. ... show more

  • Hydroponics must have
If you're using hydroponics to grow veggies (or, whatever else), these two liquids are a must to insure your plants PH levels are correct. PH up is the one I use the most - started buying that in gallon form, now
