Oh no! not another PH Question

[Naturalhi]

So I've aquired a 4'x4' tray w/ 25 9"x9" square baskets, a thirty gallon reservior, double filtered (hard) well water, and was thinking of sticking with Fox Farm nutes.

I've been watering the last of soil grown mj with the ebb n flo system I built, and studying hydrogrowing.

So far I've had no prob with PH, but from what I've read there might be problems during hydrogro.

The medium I plan to use is a mix of coco fibre, lava 'pumis' rock, and maybe some perlite. I'm thinkin' 1 or 2 floods a day 'cause of the water retention properties of the medium.

How hard is keeping PH n PPM level, the real scoop!:hmmmm:

When i first started hydro i was clueless and panicked if anything changed at all :eek:

I found myself doing everything i could to keep ph and ppm at one level... what i didn't know was this is backwards from what i wanted....

to me a Ph swing is good as it allows me to control the uptake of what the plants needs are. ;)

as for ppm this will also change as the plant grows and goes thru the cycles of it's life.... some people use a flat ppm rate and have great results but i like to use hydro for what it is intended for... (fast growth rates)

I keep my ppm right at the max the plant can uptake at all times by giving it back what it eat and what it wanted on a daily basis until all levels out around mid flower...

I find it very easy to control now that i understand why to control

Thanx CB. Guess I'll carryon with the program :D

When plants throw the PH up and then back down through the range, and look happy, then the plants are looking after themselves.
It's when you pick up the pipet and 'PH down' you ought to recognise your original dosages were wrong. We ought to look at amending or refining this.
PH has never influenced me to adjust feed, but it can tell me when I've over or under fed. Leaf matter looking strange will often happen before PH shift I've found (when something is wrong), so as we spend most of our ugly lives looking at green pepper plants that don't produce peppers, don't take PH 'shift' too serious.

Nor think PH is what you will totally control the plant by.

Acid rain can still produce a harvest........

H. Claw; Thanx I'll remember that!>)
