baking soda and vinegar are the common and most recommended pH up and down DIY additives.

couple drops tends to work for a gallon or two... but the solutions vary soooo much the only way you can tell is to mix up a few trial batches and see what you get.

BTW, you have to pH test every time you water. there is no stability to be had in municipal water... and most bottled water is from municipal water supplies ;)
 
I'm using distilled water, is that any different? And in using Vinegar, that's PH down? And Soda is PH up? I'll get the hang of this, you'll see. lol
 
vinegar is pH down and baking soda is pH up :)

dunno about distilled water... i cant be bothered with the expense or pain unless i am using well water or something equally grody :D
 
Distilled is neutral pH 7.0, its good, nothing in it.

I use R.O.(reverse osmosis) my tap is unusable, 760ppm.

A pH pen is worth its weight in gold.:eyesmoke:
 
nope, they are an electric pen that you stick the tip in your water and it reads the pH levels.
 
I only buy Hanna, for years, new one every 3 years. never a problem.
I cal. it like once a year,LOL its cool though I know them, Da Plant DOC does the same.
 
Wow! Looks like I'll need their weight in gold to buy one. Holy Cow! Those things are expensive. Maybe I can trade some bud for one after this crop. NOT! lol
 
Wait for a month or two of using that fish tank pH kit, you'll be ready to pay twice that for a pen, mark my words.
