Silver Thiosulphate

[timmyd3853]

hi have a question about mixing silver nitrate with sodium thiosulphate. i read on here somewhere a ratio to mix it at that wont fuck up your plants when you treat them but dont remember what it was. im dyslexic and it takes me forever to read anything so im asking for probably the millionth time for the mix ratio again. thanks for your help.

There is a old thread by rezdog on that me thinks. Use google.
"icmag sts" should find some threads for you.

Here you go, from here > https://www.icmag.com/forum/marijua...inized-pollen-seeds-r-c-clarke-method-as-base, I make it stronger, 1:7. Spray > 5 days spray flip(12/12) > 5 days spray. (3 sprays)

Measuring and Mixing Stock Solution "A"
* Fill your 500ml measuring cup with 500ml of distilled water
* Measure out .5g of Silver Nitrate
* Mix the silver nitrate powder into the 500ml of distilled water
* Pour the silver nitrate solution into a brown glass bottle and seal tightly
* Label the bottle "A" Silver Nitrate
* Thoroughly clean the 500ml container and rinse with distilled water

Measuring and Mixing Stock Solution "B"
* Fill the 500ml container with 500ml of distilled water
* Measure out 2.5 grams of sodium thiosulfate **anhydrous**, **OR** 3.9g of sodium thiosulfate **pentahydrate**
* Mix the sodium thiosulfate with the 500ml of distilled water
* Pour the sodium thiosulfate solution into a brown glass bottle and seal it tightly
* Label the bottle "B" Sodium Thiosulfate
* Thoroughly clean the 500ml container and rinse with distilled water

Keep Both "A" and "B" Solutions Cool and Dark!

Mixing and Diluting STS
The next step is to mix the two stock solutions together properly, creating the actual Silver Thiosulfate Solution (STS).

Before using the STS, it must be diluted to a weak solution for spraying!

* Measure 50ml of stock solution "B" with the 60cc syringe and gently squirt it in the 500ml glass measure
* Thoroughly rinse the syringe with distilled water, or change to a new syringe
* Measure 50ml of stock solution "A" with the 60cc syringe
* While whisking solution "B" in the glass measure, slowly squirt solution "A" into the glass measure in less than 30 seconds
* Pour the mixed solution into the 32oz brown glass bottle with black sprayer top
* Add 900ml of distilled water to fill the sprayer the rest of the way, leaving room for a little bit of surfactant
* Add yucca extract in small amounts and shake well
* Test spray on a leaf to if solution still beads up and rolls off
* Add additional yucca extract and shake well, until the solution spreads across the leaf instead of beading up
* Thoroughly rinse all tools using more rinse water than usual


You now have a sprayer bottle with a 1:9 dilution of STS and water.

thanks guys i see where i went wrong now. i had the ratios on the 5 parts to one part right but i didnt dilute it anywhere NEAR enough LOL was more like 2 to one.
