Lemon juice acts as an acid to lower your Ph, not sure what could be used as a base though. Also might not be the best to put in a hydro system.

I am gonna catch shit for this but believe me this works! I have been using this for around 8 months now and I have saved a ton of money.

For PH DOwn
Go to an auto parts store and buy sulfuric acid yes Battery acid, You can dilute it to around 1/2 cup acid to One gallon of water.

If you need PH UP go to Lowes and Buy Roebic Drain opener its 100 percent pure Sodium Hydroide. Do NOT use drano or anything else you need 100 percent sodium Hydroxide. mix about 100 grams of the stuff to one gallon of water.

Now you just spent about 15 bucks for all the ph up and down that you will use in 2 years.

If you check with commerical growers they will tell you the same thing, Sulfuric acid for down and sodium hydroxide for up.

Just dont tell any weed growers about this, (Sproutco was banned for it) But believe me it works. However if you wanna keep paying the Hydro stores for water to the tune of about 30 buck a gallon go ahead.

Uhh ohh I think someone is gonna string me up for this!!!!!!!!!!!

^^^^^ BAN THE MAN.


Yeah, the sulfuric acid is a sound idea.

Not to sure about the sodium hydroxid....sodium is salt and can be a problem.

I have read about using potassium hydroxide instead as the plant can utilize the potassium.

As to the concentration and the product to use I do not know.


His contempt for objective truth is the rejection of democratic accountability, an implicit demand that his supporters place undying faith in him. Because the only measure of truth he accepts is what he claims at any given moment, the power his supporters vest in him is unlimited. Sound familiar?
If we must have an enemy at the head of Government, let it be one whom we can oppose, and for whom we are not responsible, who will not involve our party in the disgrace of his foolish and bad measures.
In the United States, under our Constitution, a free press is a check on politicians of all parties. If we are to demand that other countries respect the tradition of a free press we must also practice that here at home.
Let the people know the facts, and the country will be safe.

Thanks guys I thought I was a dead man for sure!

The sodium hydroxide doesnt affect your ppms at all. I know it sound crazy for stoners like us to be messin with this stuff but it really does work. The advantage of the Sodium hydroxide of the Baking sode it that it holds up longer with less. I was skeptical at first too but I did a lot of ponderin on this as my man Carl says (slingblade) and then I tryed it and no bullshit it works. I have had a few beers tonight but I aint that F up yet I aint messin with you it works. (I have been known to be quite the wiseass later in the evenin but I am on the east cost and its still early yet.

Side that these are serious chemicals and shoulh be handled with care. No children should try this its for advanced growers ONLY!!!!!

yea, fred's tellin you the truth, the stuff works great.

i was the one that posted a recipe in Sproutco's thread.

i had been researching it because i'd seen and people talk about using it, all the time on hydroponic gardening sites.

So i found a recipe at a site.

The guy's recipe was just for one liter.

It was ratio'd at 19-1, distilled water and acid.

A U.S. gallon: is 16 cups.

i figured out if i poured out a cup from a brand new gallon of distilled water so i could get a cup of the acid in, that was 15 to 1, not far from 19 - 1;

Later on after about a month of using it on my plants, i posted it up in Sproutco's thread, because he didn't have a recipe in there, just mentioned it could be done.

============================== ============================== ===============
Sproutco got banned for publishing p.m.s somebody had sent him while they were arguing Fred.
I saw one of the mods tell some guys who were speculating why he got banned.
