pH in organic growing

[Verite]

Sorry but what you see as a smart ass remarks are valid questions. When your bs has no valid science or understanding to back it up then why wouldnt it be questioned?

When growing in an organic medium...the ph will always balance out, give or take a few points. So if some elements are available in higher quantities at different ph levels....then when you allow the ph to drift back up after feeding...the elements that are released more readily at lower levels, become more available to the plant as it drifts back up. I'm not talkin about a ph of 4 or lower when you feed...but I thought that should be understood without having to mention it.

When you got nothing to back up these statements how can anyone expect it to be anything close to the truth? Without it anybody can talk alot of shit.

I have never heard of allowing a plant to absorb some nutrients at one ph and then allowing the ph to drift to allow absorbtion of other nutrients. Why not choose a ph that allows all nutrients to be absorbed to some degree and keep that ph?

That does sound better sproutco... if you feel like messing with all that pH stuff. I can definitely say from 3 years experience using dolomite lime in the soil at 2 tbs/gal, that I've never had any pH problems. And I've watered with a pH of 5.2-7.3 with no problems. Sure it's probably a tad better to just stay in the range all the time but let's face it, if most of us didn't mind pHing stuff like mad scientist we'd be doing hydro!

Before the lime I had the digital pH pen and all the calibration solutions. And had good results using them. But since I have been using the lime I'm getting the SAME results without the hassle....FACT.

Here's a plant that was watered a couple days ago with a pH of 5.5 in peat and perlite with the lime.

If you've never heard this then you need to spend more time in the hydro section, ph drift in res is often a concern with newbs and is usually a good thing as long as it stays within range hoever it's much less important in soil than in hydro, that's the beauty of peat and humus rich soils.
I actually alot of this ph hype is rooted in the widespread use of hydro ferts and semi organic blends as opposed to fully ammended and composted soil mixes with light teas and guanos.
The first chart is in soil, the second in hydro, the others are some perspective on humic acids and humic substances.


Peace

hi...

i want tou know if i use.. wood ash for ph+ and for ph- i use "ksino" i don't know what is the name of it in your lounguege...it's a yellow botel whit something like lime in it....

are those 2 good to adjust the ph in my organic indoor grow??

thnx...

ph whats that? i quit checking ph like 8 years ago. as long as my soil mix has lime,wormcastings and compost. and i have watered with earthjuice freshly mixed with real low ph no bubbling.

great , and very interesting thread guys , I never have bothered with ph myself ... but I understand a little more about it in soil now ... as a fish keeper I understood that 'hard' water is from regions where the water trickles through rock , and soft water was from more 'peaty' areas ... but I still fail to understand exactly why a small fluctuation (from neutral) of between say 5 and up to say 8.5 has on the plant ,, I aint saying it dosen't,, I just mean I dont understand ..

you quit before 8 years...how many years you grow...?

i don't grow more than 2 years..we are not the same..

can somebody answer my question...???
