Not using this method as yet. I sometimes plant my outdoor patch a bit early so that it flowers and then revegges and this definitely makes them super bushy from the get go ( and also lest me remove any males early) , but they can take ages to revert back to grow and I have never been convinced it’s the most productive method. That said if I can speed up the process then this might be a whole different story.
I have yet to go full term on one that I have used silver to speed up reveg, tbh most times I find revegging to be so slow that it’s mostly faster to be starting again… unless of course it’s one of those special pheno’s that doesn’t show special till it’s too late to clone… I don’t know if this treatment might cause balls later when you reflower, but given the initial dosage and time passed for the AgNO3 to be metabolized I would be amazed if there was an issue with stray bananas.
Just by way of comparison ( my own ‘baseline’ of sorts) on how much it seems to speed it up, this is the plant next to it that wasn’t injected, you can see it is revegging but is miles behind the other one.
