If you get the male balls at just the right time you can save them in a plastic bag in the frig. You cut them open and use a qtip to rub a little pollen to just a few flowers and you will only get seeds on that spot every thing else will be sensi. Hope that helps. I have been on lots of different kinds of forum and most of the time if info is right the guru's can take a break from answering alot of questions, but his wisdom is always welcome.
