I bought some ph down 81% phosphuric acid yesterday, which is for hydroponics, im a compost/soil grower, will it be ok to use? I only need to use a little bit as I need to lower my ph by about 0.3 - 0.4.
Peace!

Fear is not the natural state of mankind
yes, it will - just be extremely careful with the stuff - bit like the start of Alien if yr not careful, so drops at a time and mix well and TEST! before using - i've never bothered with the stuff and my pH is 7.5, soil is very forgiving so long as you treat it lightly
good luck
Researchers have discovered that chocolate produces some of the same reactions in the brain as marijuana.
The researchers also discovered other similarities between the two but can't remember what they are.
Thanks for the help and warning BigBudz.
Peace!
another piece of advice when using pH up (Potassium Hydroxide 25%) or pH down (Phosphoric acid 81%) is NEVER EVER allow these two chemicals to mix together while in their undiluted state!
it can explode!
!!!BOOM!!!
keep it safe folks!

Phosphoric acid
This acid is also used in many teeth whiteners to eliminate plaque that may be on the teeth before application.
Potassium Hydroxide
in 2005, an estimated 700,000 to 800,000 tons were produced
