Perfect pH?

cemchris · Aug 23, 2011

So according to that chart 5.0 would be cherry? Anyone ever run it that low? My tables go from 5.5 to 6.1 before I adjust it back.

I have run 5.2. That was the best stable pH i have tried.

Swing destroys it in ime though.

So a swing in ph is the best way to go in your opinion?? What would be the best range in ph swing?? Thanks in advance for your help!!

I hear you about the chart D.S., and I believe there is relevance to the chart. However, I have been getting unbelievable results in coco using 5.8 as my go to PH for a year, 0 issues. Lately I have been letting it go up as high as 6 occasionally and its all good.

I think certain mediums may benefit more from PH swing. For example, in the UC or DWC it sounds like PH swing is beneficial. I've heard many experts say they let it swing wildly. I've also heard some coco experts say that you are asking for trouble if you go over 6.0 PH in coco. When I was in rockwool I would go between 5.5 and 6.3 with no issues.

For me though I'm sticking with 5.8-6.0 in coco. If it ain't broke, I ain't fixin it.

I ran my ph in coco for quite a few successful runs above 6.
I would shoot for 5.8-clones,6.0-veg, 6.2 bloom.
I think im gonna stick around 6.0 for bloom this time though.

5.8-6.0 is my recommendation for coco... i said that a few times i think. It has a different chart (next to the hydro one.)

This thread is in the UC section and thus implicitly geared toward that system. Not that i mind talking about coco, but unless specified, UC is the system in question.

Sorry D.S. my bad man. Forgot to look at what forum I was in.

I swing but not that much and it is usually a slow decline from 6.3-6.5 to 5.8 at the low end.

I like 6.2-6.3 for rooting clones and seedlings, 6.3-6.0 for veg into early flower, and 6.0-5.8 till the end..

I used to jack the ph to 8 or so for a few days to make the big fans fall off real easy almost by shakin the tree boss...and the harvest and final trim

Tex

what medium is this for.And what do you ph for coco.thnx

It's my understanding that as a plant gives up an H+ for a nutrient cation the concentration of H+ ions increases thus lowering the pH.
And as the plant exchanges an H+ for an anion the concentration goes down thus increasing pH.

I could be wrong.

thats awesome someone actually knows the plant process +1 mrbong

5.4-6.1 veg. 5.1-6.3 flower

According to this chart P and Mg are un available at a ph below 5.8
There are a bunch of Hydro Ph charts who is right?

Honestly I just play with organic soil. In this case Roots Organic. From my perspective ; I prefer to target my ph at 6.7. I get the best result from this PH. I don't bother with checking my run off from organics since my girls are looking excellent. If you look at the ph break down. 6.7 seems to be at a great marker. Many folks recommend 6.5 for soil, but between 6.5 and 7.0 is the best choice!

gettogro · Oct 19, 2011

thanks for that helpful post. That should work well in a undercurrent.

Im gonna have to say that I got better results with a 5.5 to 6.2 swing throughout the whole grow... Ill never go below 5.5 again that black and white chart fails to mention you will have a water uptake problem at low ph levels.

Yeah the difference between the two charts is what initially prompted me to post this thread. I personally trust the white chart more for several reasons.

First it is an AG industry standard, and found in many text books and published articles where as the colored one is only from a Cannabis source which can almost never be trusted. Also i have used it for years and my experience correlates with the numbers shown.

I am open to differing points of view on the matter however. What do you think?
