General Hydroponics pH Control Kit For A Balanced Nutrient Solution

My shipment arrived slighly 'wet' inside the plastic bag and the paper labelling within; however, each indivdiual jar was properly sealed -- so... dunno where the wetness came from..The product itself works well; test is easy to conduct and easy to read with sufficient color variation to divine even 7 vs. 7.5 vs. 8 PH, etc.PH down is quite strong, a little goes a long way (about 1 capful pulled my 3 gal bucket down from 8.0 to 7.0 when measured again after 3 days).If I had a suggestion would be to also sell this kit in lower cost formats that do not include one of the PH up's or PH down (i.e. I dont really see myself using the PH UP, so therefore I would have preferred it not be included in the price).

This is simply the best product for what used for PHOPHM simple accurate very efficient amazing life for the money gives it great functionality with the pH down acid and base plus it comes with a tester tube reactive agent to test you ph levels!!!Amazing

A must have. Honestly though, get the larger size pH down as you’ll use that more often.

The pH testing part of this product is good. However. The instructions are vague when stating to use 3-5 drops when testing the pH. There are no instructions on how or how much to use of the pH Up or Down when you need to use them. You just add a tiny bit to your water and retest each time until you get your proper pH level you need. I use this for my small home hydroponics system. I wish it had a better pH comparison chart, one without writing on it.

It really does make a different in your plants to make sure the ph is right in the water, this kit is awesome!

I’ve been using General Hydroponics pH Up and pH Down for maintaining the pH balance in my hydroponic nutrient reservoir, and I’m impressed with how reliable these products are.First off, the formulas are highly effective. A little goes a long way, which is great for precision adjustments without overcorrecting. Whether I need to raise or lower my pH, these solutions act quickly, giving me full control over the nutrient solution.One thing I really appreciate is how easy they are to use. Both products are well-labeled with clear instructions, making them beginner-friendly while still being ideal for experienced growers. They don’t cloud the water or interfere with nutrients, which is a big plus when you’re trying to maintain a stable reservoir environment.I’ve noticed that using these consistently has improved plant health. Maintaining the correct pH ensures that the plants absorb nutrients efficiently, and I’ve seen stronger growth and healthier root systems since adding GH pH Up and Down to my routine.If you’re serious about hydroponics, these are must-have tools. The bottles are durable and come in various sizes to suit any setup. Overall, I highly recommend General Hydroponics pH Up and pH Down for anyone managing a hydroponic system. They’re reliable, efficient, and worth every penny.

Perfect for cannabis growing. Just make sure you let your RDWC circulate long enough to get the right readings.

Excellent, timely, good packaging, quality product.
