Easy to use.
Love this product. Vegas water needs around 6 with a fill up and 9 with a start off. Would love a larger size in the future.

Our local tap water is so out of balance with chemicals. This product helps my plants have a fighting chance at survival.

Love how long this product has lasted, I have had my grow stand about 6 months. I have had to use this product regularly due to city water. So glad that a little goes a long way.
