Advanced Hydroponics of Holland

Holds pH well

Yes, wow, what a great supplementary product! Awesome!

For me, this is the best PK additive out there. Really delivered great results and highly recommend!

Only used it for adjusting pH during the final plain water feedings, but it did the job perfectly. Easy to use, stable pH adjustment, and definitely more convenient than homemade alternatives.

AHoH nutrients are very easy to use, and the results are worth it. I recommend them.👍👍

Only to lower the pH, both in growth and in flowering.
