I like this idea.
Thanks!

I sit my black plastic pots on some timber spacers that sit in saucer. I suck up the runoff, which I give once or twice a week with a syringe. My wet & dry vacuum is too noisy for my plants sensitive ears.

Brwnthmb The idea is to let the bottom get air. If the plastic saucers are preventing air from getting to your bag either by direct contact or allowing the bag to sit in water for more than a couple hours, yes, get rid of the saucers.
This is a picture of what I use. These sit in saucers to catch runoff. Search your own brand if you are interested.

I have a ph60, but haven’t used it yet. (I also ordered the vivosun “model pos” since it was cheap and recommended.) I will try the apera when I get home for comparison.
I expected the Vivosun to calibrate as advertised at least. There’s some reason it didn’t get to and stop at 5. It’s also a puzzlement how it was repeatable afterwards measuring tap water and the sample’s ph.

Get an Apera PH60 or PC60 with calibration fluid and storage fluid.

They have a shop on Amazon.

Toss that POS in the bin once it arrives.

Thanks for the tip on elevating the bags! I would never have thought of that. Do you also discard the black plastic saucers that fit onto the bottom?

1 US gallon = about 3800ml or just under 4 litres. 750ml is a bit under a US quart which is 948ml

1 imperial gallon is a bit over 4 litres. 1 imperial quart is 1.13 ltrs

Something like that.

Edit. Zoom on using your phone on the syringe and put some blue tape or similar at 2ml 4ml or 5ml 10ml then you can keep putting off those reading glasses like me.

Flat, yes. But you need air to the bottom of the bags just as you need it to the sides. They need to breathe or your chance of root rot goes up.

What do you mean get something under your bags so they’re not flat? Do you not want a flat surface to set the bags on?
I have some ph up but I need to get confident with measurements first.

[Gingerbeard]

So, you got the setup that lowers pH. No big deal. Get confident in your meter and dosage and look to get yourself some pH-Up. Whatever brand.
Your plants are looking great in the last picture! Get something under your bags so they are not flat, before you run into issues.

i think I’m using the meter correctly; and it’s a vivosun meter (the cheap but recommended one). I measured the before and after the same way, suspended in a one liter pitcher.
However , the calibration didn’t go exactly like the manual said it should, that the meter would get to 5, then blink 3 times, etc. so I don’t feel confident in the calibration. However the readings are very repeatable when measuring tap water, and the sample at 6.86.

edit; I am trying to add 1/2 tsp/ gallon (0.5ml/750ml) but the syringe that I’m using is hard to read.

I didn’t raised the ph back up. In my defense this was the first time I’ve measured ph, but only the second time adding bloom nutrients.

[Gingerbeard]

You got something wompus about your before-and-after nutrient pH.
I did a little google and found the answer "No, Superthrive Bloom is a plant nutrient designed to be used during the flowering stage of plants and does not lower pH."
When did this start, or, when did you notice this? Have you upgraded your pH meter? If your pH lowers with the more you add, are you adding too much in the first place?

[Bluey]

How are you raising the pH back up?
