bought some. Just checking. Ty
Ive seen alot of threads talking about tiny amount of pollen being made.
I know with gibberellic acid.
PPM Strength really has a huge impact on how affective it is on cracking old seeds.
I made mine, and will likely go through well over a liter of it by the time I reverse one plant. Perhaps the issue is not the concentration but the thoroughness of coverage. I can't imagine getting a whole plant reversed with one of those small bottles of stuff that are sold on Amazon or EBay.
I could be FOS, but it is my understanding that the ultra tiny colloidal silver particles in the solution get inside the plant and move around throughout the plant, they don't just stay where they are applied. If that is true, then doing the whole plant and giving it a good soaking may be what gets enough silver in place throughout the plant to achieve strong reversal and good pollen production. If you just do a small part of the plant, or use a small quantity of solution, you may not get concentrations within the plant high enough to accomplish strong reversal and good pollen production.
On the main thread on this topic, (yeah, the sticky so long that almost no one would read the whole thing any more) one of the posters stated that the maximum concentration of colloidal silver is about (as I recall) 20-30ppm, and that any more colloidal particles that may be initially in solution will simply join into larger particles which do not penetrate the plant. The post seemed authoritative, and if it was, it means that there is no such thing, particularly among purchased options which have been on the shelf for who knows how long, as
colloidal silver significantly higher than 25ppm. This would again suggest that it is the quantity of solution applied that is the issue, not the concentration.
Anyway, I will use my first liter and if necessary make another, and we will see what results. If I were you, I would get yourself some silver wire, and make your own next time around. If my experience is any indication, the wire will last for dozens if not hundreds of liters of saturated CS solution.
Good luck with your project.
