I use vinegar (white - 5% acidity) and have no problems with stability. Let me get real specific so others get an idea of what I am working with rather than just saying, "I use vinegar". I have 5 gallon buckets with 8" net pots. It takes 3 gallons of liquid to get the level to the bottom of the net pot. The solution/nutes is a combination of water, SMS-90, and Regen brand "Grow" (). I use "Grow" because I know the guy that makes it and they make it on site in my area. I am lazy and don't own a R/O filter and don't bother with letting jugs of tap water sit for 24-48 hours before using.I've heard lemon juice and I've heard vinegar and I've heard people say the used it and it didn't work. Are you speaking from experience or from hearing. Do you use pure lemon juice? I've heard the store bought lemon juice ain't worth a shit. I would like to know from somebody that actually uses it
About once a week, I change out the bucket. To do so, I lift the growing plant/net pot out, put it on top of an empty bucket, drain the bucket, clean, put it back in the growing area and make another batch of solution.
I take a 5-gallon bucket, put an empty net pot on top, take the shower hose attachment and fill to the bottom of the net pot. Then I add the SMS-90 and Grow, take a whisk and mix, and add vinegar to drop the pH (my tap water starts at about 8.0 pH and I add about a tablespoon of vinegar). I put the plant back on top of its bucket in the growing area and then pour the new solution over the growing media so that I can cover all of the media (Grow Stones) with the solution and walk away. I just checked the pH of one of the buckets before writing this and after one week, the pH is still where I want it.
I spent a year once working in a college chemistry lab when I was studying chemistry in college (I am NOT a chemist). Late one night, I needed to adjust the pH and the stores were all closed and even Amazon could not deliver anything on time....so, I used my old knowledge of vinegar vs. baking soda and have been happy ever since. And the vinegar makes a great bi bim bop sauce!! I have very serious epilepsy and would rather use vinegar/lemon than battery acid:) But maybe if I had finished that chemistry degree, I would have those concerns:))
