I have been testing sulphuric acid (battery acid I baught at the auto store) for about 2 weeks now. My seedlings are taking off while using it and the nutrient solution I am using for them is PH stable and clean while sitting stagnant in a spray bottle.

I haven't had any problems with my sulfuric acid from the battery acid. Just remember to get clean fresh acid and not used from a battery lol... That being said there are some other sources. Some "professional" strength clog drainers are actually a strong acid in a bottle.. I have seen some in ace hardware and similar places and they tend to be in a bottle wrapped in a plastic bag. I would do some research on the brand that is available to you if you choose this route. they tend to be less clean than battery acid depending on the company that makes them.
