Humboldts Secret pH Up for Plants | Hydroponics and Soil pH Adjustment | Concentrated Potassium Hydroxide Formula | Raises Nutrient Solution Levels for Strong Root Growth and Stability | 32 Ounce

Decent price quality product from Humboldt very easy to use very powerful and effective just like it's partner pH down a few drops goes a long way may be a little pricey compared to other brands but you will use a lot less than other brands

Look at all the other one star reviews!!! There's a very good reason! This stuff is diluted trash. If not just straight up water! Absolute garbage DO NOT BUY! The people that are selling this need to pull on Epstein! The back label of this product is clearly for pH down and not PH up. So that's number one. Number two is that it only has a TDS of 1030. There is no way on Earth that pH up should have a TDS that low. It literally does nothing to the nutrient solution.. this is insane that this product was sold like this for those two reasons. Unbelievable! Apparently Humboldt's Secret is dilution, and ripping people off. This is some S I'd expect meth addicts to do!

Good stuff

Good stuff. Very little needed. Highly concentrated.

I’ve been using this hydroponic pH controller in my system, and it has quickly become a must-have in my gardening routine. The formula is incredibly effective at increasing and optimizing pH levels, which is crucial for maximizing nutrient absorption and plant growth. I’ve noticed a significant improvement in the health of my plants, as they’re clearly benefiting from enhanced nutrient uptake. One of the standout features is how cost-effective it is. The concentrated solution means you only need a few drops to see results, making it an economical choice for long-term use. A single bottle goes a long way, which is a huge plus for those of us who want great results without breaking the bank. The clean and simple formulation is another reason I trust this product. It’s made with water-soluble potassium hydroxide and is completely free of dyes and additives, so I don’t have to worry about it harming my plants or contaminating the growing medium. Whether I’m using it in my hydroponic system, coco cultivation, or even soil-based setups, it’s versatile and effective across the board. What’s more, this product was clearly designed by experienced growers who understand the needs of plants and gardeners alike. The thought and expertise behind it are evident in its potency and ease of use. Overall, this pH booster delivers outstanding performance, and I highly recommend it to anyone looking to maintain optimal pH levels and boost plant health in various growing environments.

I added 30ml total to 3 gallons of 600ppm nutrients. Starting pH was 6.35 and final pH was 6.37. So it’s basically 99.9% ineffective. The potassium carbonate pH up from General Hydroponics would have only taken 5-8ml to reach 7.0 from the same level. It’s also far cheaper than this stuff. Other HS fertilizer products work very well, so I was a bit surprised at the lack of effectiveness from their pH up.

Just what I wanted, when I wanted it.
