New Grower Why is the pH requirement different in soil to hydro?

Good question mate :smokebuds: I'm not sure why though as iv never run or paid much attention to hydro & its requirements. I'm sure someone will know more and post up 
I found this chart,it shows how difference between hydro & soils nutrient uptake,maybe that's it. A different optimum & availability range for hydro

Good question!
I bet there's a really long and confusing answer to this.
I've always just taken it as law, but next time i see JM online i'll see if he can drop in here and melt some brains!
And welcome to the forums Nytros!
Why not pop up a hello in introductions for a nice warm welcome from our members!

ow! NICE question. I`ve been trying to read something about it and all i could find out was that the feeding in hydro is a direct thing while soil is slower and release over time. If the Ph in hydro would be to high the uptake would suffer. But soil can handle it better and slowly.
But this is only something i read, lets hope someone wil chime in with some great info on this :High 5:

Two main reasons I would say... One is that soil contains a shit load of organisms that plain water does not, so many more processes occur before nute uptake. Also, that soil works dynamically with the feed, so it has a much greater buffering capacity.
In hydro, pH is kind of "written in stone". The pH dictates the osmotic capacity the roots have to exchange ions. In soils this is more negotiated with the micro-herd. If not too excessive, soil will tame your pH for optimal uptake.
On the other hand, hydro is turbo-charged in performance if you nail the strain's wishes

Interesting manifesto :gthumb:
