no I'm in soil Munz. What is worrying me is the PH amount now. Does Ph downer has some effect if letted stand for some hours? I read It only takes about a couple of minutes to make effect.

hey , i was thinking that ph is basicly acid or alkaline, so to bring it down you want acid. why not go for natural stuff like lemonjucie or vinegar? would they work/be less harmfull?
anyone tried these?

yes they work but only for a very short period. sal i have found that if left to stand overnight i use less ph down, yes it does work instantly, but to instantly get to my desired ph level i will use more ph down?. the ph will start to rise again about 60 hrs(approx)after ph adjustment.  also i keep my nute solution at 19c, not sure if this will have any bearing ,hey sal arent ph levels a bit higher when growing in soil????

Thx for the answer Munz. I'm gonna do a lil test on thursday or in the weekend. I'll mix some nutes and water and see if the PH lows.

Honestly I have to give you reason. I think I'm lowering it too much. Gonna use 6.2 from now on and see what happens. Reading a bit and see some opinions like 6.0-6.5. Guess I'll stick into 6.2.

Hey Salgado, if you're growing in soil, you really don't need to worry about pH levels. Potting soil will almost always have some substance added to it (usually lime) to stabilise the pH between 6.5 and 7. Your tap water at 7.2 should have no effect on this whatsoever.

When growing in soil, it is the pH of the soil that matters, not the pH of the nutrient solution. As long as you use fresh soil for every grow, you really shouldn't have any problems with pH. With hydroponics, there is no soil, so the pH of the nutrient solution is much more important.

Soil is a living ecosystem, packed with beneficial bacteria and fungi. It regulates itself pretty well. That's why growing in soil is so much more forgiving than growing hydroponically. Cannabis will be perfectly happy in soil with a pH anywhere from 5.5 to 7, but most experts agree that somewhere around 6.2 is best for maximum growth.

This is an interesting article that explains how lime buffers the pH of soil: http://www.ncw.wsu.edu/treefruit/soil/lime.htm

Thx Farmer Mick for your input it cleared me out about some questions and the article is really interesting as you said.

One thing that called my attention was that fact that a soil with PH 4 is 100 times more acidic than a soil with PH 6!!!

I'm sticking to 6.2 now and waiting for some smoke
