Earth Juice Natural Up pH Adjuster, 30 lb

I just assumed that the bottles would be about the same size as the last pH up/down I bought of a different brand. My bad. This is such a large quantity that it is way, way more than I will ever possibly need or use. This amount would be something you would need for large amounts of water that would require a lot of ongoing adjusting. Also, there is no free return shipping on this product so I had to pay to return it and also print a label and box it up. ARGH!

I grow organically and need to adjust the ph of nutrient water with each watering. Theses crystals ( both the ph up and ph down) are 100% organic. That feels good to me.

This is so easy and quick to use, just a small pinch goes a long way, get the Earth Juice Natural Up as well in case you get a fat finger and drop it to low, this stuff costs more but well worth the ease. I use a quality digital pH meter to check afterwards. So easy to dial in the right pH.I'm never going back to that liquid pH Up/Down. I'm sold on this stuff.

Still reliable. Crystalized. Best to buy if it's below freezing since liquid will freeze before you get it and leak everywhere.

Could not get pH down . could not find that out until after I ordered everything and only got the ph up.Shipping was sure up to send pH up back.

This product is just over-priced baking soda. Save yourself a bunch of money and just buy baking soda instead. Very disappointing.

Good product

Works well as an organic solution for adjusting PH. It's a granular product that I use it weekly, and a little goes a long way so start small and take a reading so you don't over shoot.
