Any auto parts store. I don't know what country you're in....but advance auto or napa type stores here in the states carry it. Canadian tire probably has it in canada. Costs about $4 per litre...and that will make a few gallons of ph down.

Drink!

yeah im considering going and getting some battery acid...

i was considering using hydrochloric... but not sure if plants like HCL salts.

I have a big bottle of muriatic acid (pool ph down) that is diluted hydrochloric and would work fine if there is nothing wrong with HCL salts

Is hydrochloric definitely a good idea? NaCl kills plants. If thats because of the chloride ion, then hydrochloric acid would too.
I think the sulfuric acid idea's the best. Don't worry, its not too harmful - the stuff you get for car batteries is only about 40%. It'll sting if you get it on your hand, but it wont burn a hole straight through it like in cartoons. In fact, I've even spilt 100% sulfuric acid on myself a couple of times - it stings a lot and makes your hands feel really dry, but its not too bad.

Why not just use nitric acid for vegg stage and phosphoric acid for flowering.They both serve two purposes, they lower your ph and provide extra nitrogen via nitric acid or extra phosphorous via phosphoric acid which are both good for you plants and will actually help them grow

Wow! Battery acid? I use baking soda to lower my ph. Works great. Super cheap too.

OH, Heavenly Father!

-any local brick n' mortar sources of high molarity base?

Thanks.

The battery acid I will definitely be collecting tomorrow. I'll get my roomie to run the dilution calcs... fuck I'll just learn it again.

please, BASE!

Like, Where can I find lime at? - It isn't a flocculant is it?

I wouldnt use lime to lower pH: it can react with sulfates to form an insoluble gunk. Not good in hydro systems. I'd recommend using household ammonia or potassium hydroxide to lower pH: all potassium and most ammonium salts are water soluble. Baking soda or sodium hydroxide (caustic soda/lye) should work too, but I'm not sure if sodium ions would be toxic to plants - they are to humans (slightly) and as far as I know, they serve little biological role in plants, much like lead and mercury do in us.

Ok, I got the down part-
But I do have to go up sometimes as well.

So I'm wondering if anyone knows a base that is as easily accessible and convenient as battery acid is.
