Thats what i am trying to do and i dont want to smoke hermie plant wich is watered with colloidal silver either
You dont water it with it
simply use a regular empty spray bottle ($2 at your local shop) to spray it onto the leaves of a known-female plant to induce the pollen.
This resulting 'feminised pollen', unlike regular pollen from a male, comes from a female so it doesn't have male chromosomes.
As a result, any females then pollinated with the feminized pollen produce seeds that can only grow into females.
iv heard some growers has reported success with just 5 days of spraying, and some had success from just 10 days, but generally about 2 weeks should be enough.
Obviously factors such as the strength of the colloid, how much you spray, and how frequently you spray all play a part.
You can if you like keep spraying until you start seeing pollen bananas starting to show, but it generally takes a few weeks before you see them - be patient.
It will also vary depending on how many times a day you spray them, as well as the strength of your silver colloid.
It also goes without saying that once you've sprayed a plant with colloidal silver (or silver theosulphate, or gibberellic acid, etc) the plant becomes a write-off in terms of smoking it.
you should not smoke any of it. Even a thorough wash with a hose won't help, because the silver microparticles are absorbed into the plant via the foliar feeding.
It's not uncommon for the feminised pollen bananas to remain closed - if that's the case simply cut them off and manually open them. You can then simply brush them against the pistils of the target female (manual pollenation).
