Humboldts Secret pH Up - Hydroponic pH Up - pH Up for Plants to Stabilize Nutrient - Plant pH Adjustment - Plant Nutrient pH Levels Optimizer (32 Ounce)

Bought this product to raise the PH for my indoor plants. Saw this brand in several forums so I thought I’d give it a try. That was a mistake, I had an eye dropper specifically for PH products from another brand. I used this slowly to bring my PH up but it took 3 full droppers equivalent to around 10ml to raise 2 gallons .020… that’s right only .020 points. Dumped in about another 20ml and about the same results. This product is horrible and a waste of money. Had to use baking soda until I can get my old brand in the blue bottle ordered. Using straight tap water that had a small amount of nutrients that lowered the PH outside of desired limits. DO NOT BUY! Waste of money.

Easy to use good instructions

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!

Hydroponics system needs this. Have not used yet but I see no issues.

Very good quality ph up
