I'm trying to bring back a legendary strain. It has pretty obviously been feral for quite a while now because it is mentioned in one of those books of famous strains, from a while back. The Aurora line I have is very stable and never herms or anything so I tried breeding to it and then back. You can find the history of all this in the Backbreed Experiment thread over in breeding.
But what Umbra said makes a lot of sense now. I mean, this is my fault. Through lack of knowledge of what Umbra noted, I failed to predict that both the F1 and F2 must be all fem seeds.
Um.. consequences.. the immediate one is negative. I have no male indicas only my clone line. I have a good stock of F2 and rather less of the F1 hybrids. All fem. So I am without a single male and the pollen I have is out of date and even if it was any use I would only be making more fem seed.
On the plus side, these types are very useful to me because the F1 is almost as potent as the Aurora and has a good amount of sativa mindgames to it. It's nice to know any seed I put in comes up fem. And I can still have some fun testing the F2 which is just beginning to flower. They're useful, zone wise, too; the F2s vegged very fast - to 2 feet - in 2 weeks then started to flower (13.5 hour day)
But to make any new seed, I will need first to buy some. A pure sativa I think.
Oh BTW - I've grown 5 of the F1 fems so far and they have been very vigorous and no herms. And a good blast!
