Max PPM for colloidal silver?

[jfarrismu]

Heyoo,

So I've been unsuccessful reversing a female plant because I started too late on autos twice. I was also using store bought stuff and I'm ready to make my own. What max PPM should I aim for? I'm really trying to make this work this time. I'm going to be doing it on a photo this time, growing one photo 12/12 from seed and the others regularly.

Any tips about any of the above?

spray in the dark, spray every day, you can go as high as you can in the ppm and do yourself a favor and get a bottle of sodium thiosulfate and silver nitrate solutions off the internet, you don’t even need to weigh them or anything just get 0.1M solutions of both and mix them 1 part to 1 part and dilute with 2 parts of distilled water preferably.
its better if you add the chemicals into the distilled water rather than mixing them directly and stir.

So are you saying there is no limit to the PPM I can use for colloidal silver? 100 ppm? 1000 ppm? 1000000ppm? Lol

don’t worry you will not be able to break 100ppms with a diy silver generator probably

Make sure you start using the CS on the plants at week one.

You really want 5 times the amount of sodium thiosulfate anhydrous to your AgNO3

i use 1 to 1 of 1N solutions of each and it works well

You can use 1:1 but you're just wasting silver nitrate. But with the small amounts used the cost is negligible.

yeah it definitely is very negligible and works the same
