Questions & Answers

I would like to verify if this product lowers the Ph of soil. Is that correct?

Product details mentioned it lowers ph of "nutrient solution" I was unsure what that meant.

Yes. And the color reflects what you would want your hydrangeas to do.

We were using a powder to increase the PH (base), but our flowers were still green instead of cheerful colors. Now we used this in a water by diluting it, it is easier for soil to absorb and we are now trying to do the opposite by lowering PH to acidic soil. Flowers are just blooming now with a different color so we will need to adjust the usage accordingly in summer

Maintaining good pH in a hydroponic system is crucial if you want the plants to live. Just like a fish tank, if the pH gets too far off, everything dies. The use of a proper watering system is critical to aerate the hydro environment as well as provide nutrients. PH Down helps significantly in maintaining the pH at a suitable level and is easy to administer. Using a pH testing kit, you can easily determine how to add more base to a system and this product does the job without harming the plant roots. Awesome product!

My tomatoes started turning red within 3 days of adding this to my hydroponic solution. I read that tomatoes like a lower ph than 7 which is what I get from my tap. I added it to my nutrient mix and added it to the reservoir. I was surprised to see the green tomatoes start turning reddish the next day. Some are ready to pick now after adding the ph down 3 days ago. Ph does make a difference for plants that like it a little lower than 7.0. I plan to add it every time I add nutes from now on.

I'm using this Black Magic product in my hydroponic herb garden, I try to keep my ph right at 6 but I when I add other nutriments or additional water I often driff up or down a point or so. As it says on the instructions use a small amount at time, I've found adding a 1/2 teaspoon at time is reasonable, then wait at least a day before re-testing. A half teaspoon moves my ph down about 0.25, I'm sure it has to do with the size of your setup and the amount your off. In any case one or two additions usually get me back to perfect. This stuff is a good find, I also use their PH up for the opposite adjustment.

This is a nice little bottle designed to help lower the pH of your soil for your plants/flowers. Generally if the pH is either too high or too low then your plants may have trouble absorbing particular nutrients, so this bottle will help you to avoid nutrient lockout! I'm planning on using it with my hydrangeas this spring as they are pH dependent and the flower colors will change.

PH DOWN is an acidic product designed to keep plant nutrient pH in check. It cleverly reflects the effect you would want with your hydrangeas with a pink-ish color to the liquid. It lowers the amount of aluminum available to make the color change. It also affects the color in other flowers such as poppies, roses, etc. USE SPARINGLY.

I was expecting a product I would use in my pool and spa. Upon discovering it was not as I expected I read the other reviews and saw where this had happened before. After reading the advice from the company on that review I asked a friend who is a certified grower if he knew anything about the product. He had used it an felt it was a product deserving of an exceptional review. He did advise that you absolutely do need a meter. This product can quickly change PH levels and it needs to be diluted using true measurements no guess work.I passed the product on to him.

So when I received it and was reading the instructions, I realized it was only one component of what needed to use it. I do not do Hydroponic planting, even though I thought it was an interesting concept. I don't know if this product can only be used for Hydroponics, but to use it I would need a PH meter. The good thing is after receiving this product and reading the Black Magic website, I might just give this a try.
