  • Very potent.
Read directions carefully. I used 5 ml for a five gallon bucket and wow it really works. Plants appreciated it.

  • Takes quite a bit to lower from a 7.5 to 6.0-5.5
It's just a very mild acid. While it maybe somewhat concentrated? It takes an awful lot of product especially for blueberry and acid loving plants. I couldn't believe how much product it took. Humboldt secret did Slightly better but what I found to work best is adding about 2 in of fast acting sulfur to a gallon jug and letting it sit for several weeks and then when you water with it it reacts with the soil creating a low more "permanent" ph. It worth noting that I did add fast acting sulfur to the soil in late spring as well but using a ph testing probe I was able to verify that the fast acting sulfur in water without a doubt worked. ... show more

  • Potent
I started growing lettuce in rockwool and it was recommended that you drop lemon onto the blocks with the start of the seedlings. However, that produced mold growth and the baby leaves kept wilting and dying. I experimented with a couple of things, this product being one of the. I can honestly say that it works very nicely. My new lettuce is thriving and all the other plants are doing well when I'm able to balance the pH consistently and gently using it. It certainly doesn't take much. I highly recommend. ... show more

  • BE CAREFUL VERY STRONG
You must use a water Ph tester with this product. It comes in a large bottle but only needs a few drops at the most to really lower the ph. I stupidly tried to guess and tragically killed one of my Bonsai by burning the roots. I got a water meter and found the Ph was 2.0 and I really only used a very small amount. Suggest getting a dropper or 3cc syringe and adjust by adding water until you get your desired Ph. My poor "acid-loving" Gardenia Bonsai paid the price. Once I used it properly it's great. Just please test before you use. ... show more

  • Works properly
Basically zero instruction on how to use it.. I mixed up 7 gallons of nutes . Put in 1 tablespoon of this product, and tested it. Did exactly what it's intended to do . Works perfectly . You just have to figure out how much to use on your own
