I finally got a soil ph meter today and it says the ph is 7.5 i want to lower it to 6.5 how can i do this besides buying the ph down someone told me on this website u can use baking soda and whtie viniger??

First of all, baking soda will raise the ph, you needed to add lime to your soil before you put the plants in it. If you're already growing I would concentrate on ph'ing your water carefully - get a good meter (digital) and if watering with tap water let it sit overnight to get rid of the chlorine.
I understand your ph prob, out of the tap mine is 8.3 & I like to take it down to 6.5 - that takes acid. I used ph down from the local pet store but have since switched to a product called Acid Magic - it is a buffered Hydrochloric acid that won't burn you and works like a charm. 1/2 cap dropped 12 gallons (two full points) down to my magic number.
Most importently check your runoff ph.

just buy some ph down.. its only 20 bucks with s&h and you get enough to last a looong time.

i cant find that lime stuff anywhere. And thats what i wanted to know which one lowers and which one raises so that would mean the viniger lowers it, also im not using tap water im using rain water. and those digital ph meters cost over 300 dollars when people on this forum i know only use cheap 20 dollars ones with good results.

dude, you can get a good digital pH meter for 30 bucks** http://www.eseasongear.com/hannahi98103.html.

Since we are talking saving money - Acid magic cost me 8 bucks for a quart at the hdwe store & it is much more concentrated and will go a lot farther than the ph down.
And the Digital meter is the way to go.

havent checked yet. But i doubt its a soil ph meter, the hydroponic meters are cheap but when i looked for a digital soil ph meter they cost $300

This one isn't digital, but looks like it prob will work ok.
