"Runoff pH is useless" or "Keep an open mind"?

Your set up is awesome. I want to do something very similar just for rdwc mucho $ tho..

I tried DWC once, and failed horribly. Like not even being able to complete my run horrible

I should give her another whirl sometime again now that I have a little more knowledge

Just swap out your buckets lol maybe some plumbing tweaks.

These could actually be used as flood and drain recirc

Yeah and now that I think of it, when I first saw your journal showing it set up I thought that's what it was at first.

Each stand getting a flood and drain? That sounds awfully cool with some creative plumbing.

‘’They would just get flooded, then the pump would pump the drainage back to reservoir, would need to ditch the coco for hydroton though

You could do it with pretty minimal cost. You got everything to maintain the rez. If you try it we could see who wins coco or hydro lol

Are you in coco or soil?

Coco

 

[jondamon]

I’ve never tested run off ph, and barley ever test run off EC either. My plants will be getting fed in like 38 minutes so I’ll capture some run off and check both for shits and giggles.

Same lol.

i only check runoff EC if my plants exhibit any leaf discolour.

i do not check runoff pH either.

Are you adding pH up?

 

[jondamon]

Are you adding pH up?

No.

once my nutrients are mixed they average 7 usually.

then I add a small amount of my premixed -pH down solution (20% down 80% water) to my nutrient mix to get down to 6pH.

What's your water source like? pH and ppm.

 

[jondamon]

Are you adding pH up?

I will add that the next day after I’ve filled my tote I always double check the pH to make sure it’s at 6.

it always is and I don’t allow my water to sit out and “evaporate” chlorine either before using.

 

[jondamon]

What's your water source like? pH and ppm.

0.2EC 100ppm @ .5
pH 7.5

So that's a YES on the pH up?

 

[jondamon]

That’s a no, I use pH down.

if I need to go up I use silica

 

[jondamon]

Will post my res stats later and try and take pics of the truncheon for EC and will drop test the pH again.

i haven’t used a pH probe meter since my bluelab dried out back in 2012 lol.

If your water pH is 7.5 it probably has Ca in it that is buffering the pH to a higher pH level.
