Hello. Yes I have. This was going back 25 years ago to the original auto... Mighty Mite.
Ordered Mighty Mite and Donkey Dick and was disappointed in both.
I took some clippings and they didn't take, so, I took more clippings and a few took, and the little clones just finished flowering 4 weeks later.
Once they start to flower there's no chance of going back to veg.
Chuck.
