Simply add a small amount to your water, mix thoroughly and check your pH levels. The pH (potential hydrogen) of a nutrient solution is a very important aspect of plant growth and proper management is essential for healthy plants and lush gardens. TNB Naturals pH Up and Down provides growers with a user friendly and safe way to maintain appropriate pH levels for optimal plant growth.
This stuff dissolved great in my 32 gallon res and required very little powder to come down. However, when I tested it out both times my ph was not stable for more than 24 hours. Went from 6.4 - 7.7 in a day (tap water is 8.2 with less than 100ppm). It was nice to try but will be sticking with Cyco, I can see how this would get very expensive overtime. I ended up feeding my plants at 7.7 because I didn’t check before watering (checked right after) and had to re-adjust ph and flush with more water. Probably wouldn’t recommend it unless you REALLY need organic ph down and you don’t mind re-checking your res at every water.
Works very well getting away from using liquid PH up or down.
Pretty easy to use and effective
