Applepoop suggesting phosphoric acid now instead of apple cider vinegar like he was a few years ago is a huge step up. Even if nitric and sulfuric acids work better, phosphoric acid is still a viable choice if you can keep P under control.

The only problems I see with using phosphoric acid is that it will interfere with nutrient levels and cause precipitates in the reservoir. There are two real problems with nitric acid; the first is the fact it used to make bombs and is strictly controlled, the second is that is has a greater affinity to fume than the others making nitric the most hazardous to utilize.
Phosphoric is expensive and will give you a headache.
Sulfuric is the cheapest and easiest to use.

He sounds like a complete noob regurgitating information he read from another board coming here trying to make a name for himself without doing any of the hard work and making mistakes to learn like myself and others have done. Now, he wants to make grandiose claims to fame by trying to slam other members?
I hope no one ever takes him seriously, that could be very costly. People could lose money and even entire crops. That could be months and hundreds of dollars down the drain from listening to some asshat.

Mistakes like inhaling sulfuric acid vapors. Not looking to make a name for myself just giving better options to Newer Growers that are safer and less expensive. I don't think anyone's going to lose an entire crop for using a pH Down similar to the commercial pH Downs . You're really overreacting I come on here once every couple years when I want to start growing again that's about as much as I care about forum rep. You take care now and don't forget to wear your 3M 6800 series respiratorHe sounds like a complete noob regurgitating information he read from another board coming here trying to make a name for himself without doing any of the hard work and making mistakes to learn like myself and others have done.

Only an idiot would neglect to use PPE to handle concentrated acid. You should at the very least use a face shield, apron, and elbow length gloves.Stop posting my thread.
I'm more than competent enough to handle a 33% dilute solution of sulfuric acid with absolutely no protective gear, I'm talking years of use.
I mean, if a 15 yr old high school student could do it...
Phosphoric acid does not cause precipitates in the reservoir, or "mess with" nutrient solution. This is one of the most misguided shitposts I've ever read.The only problems I see with using phosphoric acid is that it will interfere with nutrient levels and cause precipitates in the reservoir. There are two real problems with nitric acid; the first is the fact it used to make bombs and is strictly controlled, the second is that is has a greater affinity to fume than the others making nitric the most hazardous to utilize.

top result on ebay, a pint of "food grade" phosphoric acid. "food grade" sulfuric acid isn't any cheaper.
What you really mean is that "the shit I buy at the auto-parts store that isn't food grade and contains impurities is cheap"

I guess phosphoric acid can give you a headache, if you drink it. You know, like in a coca-cola.

"strictly controlled" available on ebay everywhere. lol.

Only a dipshit would use vinegar and baking soda.
Grown with a regular $9 dollar bottle of ph down that’s lasted two years.
Looks like you might want to feed that first one a little less N next time you run it.
Well thanks to Applepoop and his vinegar and then phosphoric acid love affairs I wasted a lot of time on this thread.
Thanks to the OP as I have been looking for a PH down that wasn’t phosphoric acid based since I don’t need more phosphorus in my grow and am happy with my current nutes so didn’t want to change them just to accommodate an additional source of P.
As for all the vinegar and citric acid users, well i tried both and neither will keep the ph down for more than a day so unless you’re changing your res every single day then both are essentially useless.
Finally the another reason sulphuric May be the best choice is the role sulphates play in terpene production. So for those that love terpinator and other terpene enhancing products, this will not only help bring down PH but will also do what those products are supposed to be doing.

Sometimes I pop in just to laugh at Applepoop years later. 
The great thing about sulfuric acid is that you can pop out and grab some at 8pm a mile away no matter where you live in the United States. I live 30 miles or so from the nearest hydro shop. Nobody questions it or looks at you funny with sulfuric acid. Nobody is following you home from the autoparts store. This is important for those who have large clandestine grows. It is the most cost effective PH. When you have hundreds of gallons to PH during each grow, the savings are a lot different than when you have 5-10 gallons a month.
