Stress can cause a female plant to throw male banana's so you can have a female plant pollinate itself and produce seeds but the seeds are almost sure to produce a hermaphrodite.
If you're after GDP the consensus is the GDP Collective in San Pablo. I've been meaning to get over there but have not as of yet. I can't wait to go though.
So spray them and get rid of it
I don't think folks that are new to this, say started in the last ten years really appreciate the value of these clubs and the genetics they have available. In one day I can make the rounds buying clones at clubs and at the end of that day have in my hand genetics that used to take decades to collect. You'd hear about a friend of a friend that might have Trainwreck or something and if you were lucky you might track it down. All this whining about clones at clubs just makes me laugh. Some of you people have gotten spoiled.
No offense, brother, but this is a weak argument. Basically you are saying that we should not demand healthy disease/pest free clones that are properly labeled because in the past we would be satisfied if we could track down some mite infested trainwreck with pm. This thinking does not facilitate growth and progress.
The state of things PRESENTLY in California (and I suspect in other mmj sates) is much more sophisticated then it was 10 years AS A RESULT OF people not satisfied with the status quote.
good luck with those! powder mildew is rampant with ken's gdp clones at his gdp collective. didnt know till 2 days after i got them, was wondering why there were spraying them before they boxed them up for me. stay away!
