GH pH Up Liquid 4 Litres

Great deal especially if you use a lot to adjust your pH for your gardens. There isn't much info on the label but you should know what it is you're getting. Research first if this is the right thing for you. It's potent and does it's job well so be careful about how much you add. Might want to get a smaller bottle of pH down in case you go too far.

I've used this for the last 3 years and I have had consistent results with it. I hardly need a pH meter now. When I mix my nutrients according to directions, I have learned the right amount of pH up to add and have consistent results. It takes no-time to get the correct pH. Buy the gal. size for the best value.

BEWARE of ordering the GALLON SIZE! They packaged this liquid "sideways" in a box that was too small and it leaked all over. The box was soaked, the bottle seal broken. I've used the product before and like it. I won't order it on line again because I lost some of the product from leakage.

shipped fast with no leaks. add 8ml to two gallons during flower and keep those leaves green. sativa can't handle a 6.0 PH, get a good ph meter and keep the feed at 7.2-7.4 and it handles well in this foxfarm soil. FIVE STARS

We grow hydroponically, and this is the best value we have found for a product of its type. I am small, and find the large jug a bit challenging to manage, but my helper person is able to manage it just fine.

a quality product that get the job done. If you need to raise the ph of your garden water this is the stuff right here. Just dont mix it with PH up(acid). bad things can happen.

Definitely a trustworthy product It’s a little weak to be honest compared to some of the competitors, but it definitely works and for the price it’s not bad at all..

i've been using this product for years, but for some reason its been taking to much product, try different product next time

This has been great. Attempting to move plants that survived in old garden but soil needed adjustment. This worked

I only use General Hydroponics PH up and down for adjusting water feeds in my hydro setup. Been great for years!
