Is there a simple way to lower ph? My water runs about 7. I'm talkin about household items. Or is it best to buy from plant store? Just tryng to save a trip. Oh yeh I'm runin a hydro.

I am running soil indoors and need to lower my pH as well. We would both appreciate any help.

hey lazydog i found this in the cannabisedge grow faq

To lower ph: acetic and citric acid will facilitate the "kreb" cycle.

To raise ph: add small amounts of sodium bicarbonate or lime.

vinegar is a dilute solution of acetic acid, so it should work in your hydro solution. if you have a ph meter fill up a gallon jug and add say a 1/4 teaspoon vinegar til u get to the ph u want, then add enuff to your resevoir or whatever you are using i guess. i have a meter but i dont have any vinegar, i am going to get some today and try it. and now that i think about it i do remember reading somewhere about somebody using vinegar to lower ph. hope this helps ya out.

ok, my tapwater is about 7.4-7.5 pH, it took 1 and 1/4 teaspoons of natural apple cider vinegar to take it down to about 6.1-6.2... hope this works for you lazydog oh, that was for 1 gallon of water btw

Try this , cut a lemon in half and squeeze the juice into your solution , go slow it will bring your ph down fast , works for me.

yea thats the citric acid at work... i think the vinegar is a lot cheaper tho. i got a quart of it for $1.19 and i don't have to squeeze it
