View attachment 858390 Here is what I got .
In the top @ 0 pmm
Out the bottom @ 385 ppm
In the top @ 6.7 ph
Out the bottom @ 7.5 ph
,,, Dont know what that implies ,,,
That plant got 2.5 L of water yesterday .
I just put 2L in the top over 7 mins .
Had 1L out the bottom.
H]
Tried that trick again today .
With a twist
I buffered the RO water up a bit to 150 ppm , to slow down the swing.
I added "rootfarm" ? potassed based ¿ "ph down "
Knocked it back right to 5.4 ph
In the top
150 ppm
5.4 ph
19C
Out the bottom
666 ppm
7.3 ph
16-17C
I have been following along the manufacturer's nute sched , ramping as we go .
They call for 1000ppm solution
I am closer to 5
What am I seeing here ?
Am I correct in believing that it is important to watch what is running out of the bottom of the pot in my particular situation?
I have read when watering, that you are Ph'ing the for the soil- not for the water.
Am I following the right track?
Does that mean, staticly, my roots should see an ideal pH when the water is exchanging with the atmosphere and soil ?Is that happening only when I water?
Have I exceeded the maximum allowable number of questions in one paragraph?
When I built soil for my planted Aquarium I used peat and sphagnum heavy soil, as I intended on injecting CO2 into the system, increasing the CO2 while lowering the pH.
The poor sods that used coral intended or calcium-based gravel had a unique dilemma.
As the water became more acidic, the calcium would disolve and enter the column whereby increasing the hardness whilst inturn, raising the pH. The CO2 controller would see the rise and continue to inject CO2, whilst, in turn, disolving more minerals .
The more acid we added the more minerals we dissolved .
Am I fighting the same battle here with my soil?
