@InTheShed , thank you a zillion!
I just got a break. We are hurrying before Shabbat, but I can make time to do this.
This is why mixing your own soil without knowing how the ingredients will interact makes the resulting grow a potential crapshoot! Properly made soil should have a pH in the mid 6s and not need pH adjusted water.
Here's how you do a slurry test. It requires distilled water and a calibrated pH meter to work, and this is how to do it:
I got three 550cc bottles of demineralized water.
I do in fact have a pH meter. I have never used it before, but it doesn't look too hard! And I have good coaches here, haha!
I do have a scale, which I have also never used! Lots of new vertical learning curves for me today! Haha!
• Take samples from a few different places where there are roots (dig down a bit rather than just use the top - I often stick a spoon down the outside edge of the pot to grab some from there as well)
Ok, I have a pot that was soaked the same as the others, but the seeds didn't take. It has been damp very similar to the others. Will that provide an accurate sample? Because I can take from that pot without bothering any of the other plants.
Are there any holes or problems with that theory / scientific technique?
(I can bother a live girl, but if I don't have to, I'd rather not....)
Oh, by the way, happy day!!
I should add, the girls are looking MUCH healthier with the new "dog water" (haha)!
I "topped them off" before Shabbat (haha), and we will see how they do! They all look greener, and happier.
I was almost shocked at how much some of them grew. I don't know if they are going into stretch, or what, but the Northern Light CBD Autos put on a few inches, or something! I had to break out the training stakes!
All the older girls showed massive growth since Fido dog watered the water!
All that from a free "fertilizer"?? Haha! I think I like this a lot!!
• Add an equivalent amount of distilled water as grams of soil (10 grams of soil, add 10ml water). If that doesn't make a slurry, use enough distilled water to make a stirrable-but-thick slurry.
Ohh... you want precise measurements...lol!!
Ok, but first, please let me show you where I dug.
I don't know if you can see this, but I filled the rez before I planted the seeds.
I filled the SIP with said aforementioned "George of the Jungle silica mix", but then I dug out about a Solo-cup's worth, and backfilled with a local organic VEG soil.
On this particular run I did not pre-wet the backfill soil, but I will be double-dog sure to do that on all future runs!
So, to wet the backfill, I poured some of our special creek water that they put in our pipes, that had set out for 24 hours + (because I have not got the water report back yet).
Then I added some liquid myco and Re-Charge to the water, to soak.
And I don't know if you can see that glisten, but is that the re-charge glistening? Or what formed crystals in that inner-cup-o-VEG-soil that had Re-Charge poured on it?
So I dug down to the OUTSIDE of that "Solo-cup-o-VEG" soil, in the "Jungle George Silica Mix", until it got good and moist.
I'm not sure, but it was moist about 2" down, and I dug maybe a good 3" down. (I dug AROUND the veg mix.)
The water level is down about an inch from evaporation (or whatever), but the soil is still moist.
If I should dig down deeper, I can, but this looked representative of moist soil.
Here's the sample.
Do you need deeper than that? I can easily dig down closer to the rez, if it makes a difference.
The soil is moist, but not wet.
I can try to measure out 10g, but that is high-tech for me! Haha! I will see if I can figure out how to use this new scale.
I have no idea how to calibrate the pH pen, but I am hoping the instructions will be clear.
It seems to have batteries, and sets to zero.
Is there any trick to it? Or is it just as simple as all that?
• Stir it up, wait 15 minutes, stir again. Do that for an hour and then put your calibrated pH stick in the water. That's the pH of your medium.
Ok, I will see if I can figure out 10g of soil, and 10g of water, haha!
My inclination is just to mix it up until I get a slurry. Is that good enough? Or do you need 10g-10g exactly?
And put the probe directly in the slurry, correct?
Any corrections or suggestions are greatly appreciated.
You can run it on the cooked stuff in the can to get an idea of what you're working with.
