I have an Alien OG plant that I want to regenerate just for fun. It was grown indoors so I was wondering if I were to re-veg the plant for for a few weeks on 20/4 and then put it with my outside crop would it begin to flower before the others? The light cycle in my area for the next 3 months would be around 12/12 and go on to 14/10 so this is why I think it would work.
if you successfully re-veg your plant, meaning that it's converted back to vegatative growth, then no it will flower at the same time all your others do outdoors. Some strains will flower before others though just through genetics.
