I need this question answered as im not understanding why we lower the PH to 5.8 with COCO.
If anyone knows why this is done let me know.

Why change PH to 5.8
- Thread starter Hammerhead
- Start date
OK thats fine I stil would like to know why it needs to be lowered from soil??? Soil is 6.5 why is coco 5.5-6
for more calcium availability......
i got my best yields when i let my ph drift up from 5.8 to 6.5, over a weeks time......

yes I know that but why is that bad????
?? more ca I USE CAL/MG all the time in soil why not use it in coco??
How do you let it drift. You start low and just water as the PH rises?

ph is a way of measuring you soils acid and alkaline levels
some soils will interact better with a lower of higher ph...
ie the soil has a ph of its own, so you want to complement the water and the soil together...
basically that's a very simple explination

You said this is why we lower the ph to 5.8 to get more Ca right?????? If that true why not just use cal/mag to do the same thing while keeping the PH at 6.5??

So just beacuse its made from COCO it requires a lower PH to work properly does that sume it up????

Basically it's because of nutrient availability. Calcium is available in the 5.8 range in hydro (comparable to coco) while it is almost above 6.5 in soil. Also there is a difference for the other nutrients as well. Here is a handy file that someone on this forum passed on to me.
roots bind elements in the water to them and up the plant.
if the roots cannot bind the elements you are outta luck...
so ph levels will effect the roots ability take up nuts due to the binding ability which ph effects

thats for HYDO WHERE IS THE CHART FO COCO
I will ask again. Since the medium is made from coco it requires a lower PH range to work properly. Is that a correct statement????
WHY IS coco the same as hydro??????? Because of the PH range??
Im sill confused. If I take some COCO and make a mix of all my amendments just like I would in soil including buffers. Why would coco not work just like soil..
yes,
if you read my two post together you will note that the soil and water inter play with one another, the second post explains how.
so some soils will pull ph up or down
and by adjusting the water you will help balance this out.
so to your question the answer is yes.
If I take some COCO and make a mix of all my amendments just like I would in soil including buffers. Why would coco not work just like soil wouldnt the buffers keep the coco at 7??
Ok I will try it and see what happens thanks for the help Bfriendly and Krunch
this is a valid chart, the word hydroponic should be removed, it is misleading, but since most growers used to be hydro that's why it appears. nothing to do with a Hydro specific chart
unless you're hydro, it's all soil, just dif mediums of soil... coco, peat, top soil... all are soil(s)... just being anal lol
these ph's of 5.8 or 6.2 are rules of thumb
to get it right you need to check your drain outta tha pot... so what comes out of the bottom of your pot, that's what you want at 5.8, no matter what medium you are using...
the idea is that if you have a drain ph of 5.4 you'd probally go with a watering ph of 6.2 to get you in the middle at 5.8 make sense... so if you have a drain of ph6, you would make your water a ph5.6... get it with those examples,
you are trying to make your drain 5.8 no matter if it's hydro, soil of any medium...
the rules of thumb are misleading
Im very familiar with that chart. It did not answer any of the question I wanted answers for. As we all know I can buffer the ph so I can make the coco just like soil no???
See my post above about making a mix with coco would that not work????
