The ruderalis genetics are part of the breed simply to make the plant flower regarless of the photoperiod it is on. This happens because the Ruderalis is native to areas which the days are longer than the nights, making the plant adapt to it. The kind of Cannabis that produces the psychoactive cannabinoids and others needs 12 hours of darkness to start making flowers, so if it receives more than 12 hours of light in a day it will just keep growing and not make flowers, which is what is consumed since the trichomes grow mostly in there. Now, when you cross a Ruderalis with one of these other species you get a strain which will be as psychoactive as the photoperiod strains it has as one of its parents and it will also start making flowers regardless of how many hours of light it receives, be it 12 or even more. You probably already know it all, but it's good to leave it in here for those who didn't.

Now, why in my opinion autoflowers are a good option sometimes? Sometimes 2 weeks extra in the vegetation period can be the difference between a plant that will yield half a kilo and a whole kilo or more. But to have to wait an extra 2 weeks can be too much for someone who is really in a hurry to get some medication, especially if you already have to wait several weeks for the whole thing to be done. So you can put down some autoflowering seeds at the same time you put down your photoperiod ones. This way you can leave the autoflowers wherever there is space for them, be if the flower or veg room, you know they will be done from seeds to harvest in about 2 months and a half and you will not have to hurry putting your photoperiod ones into flowering too early sacrificing a possible extra half a kilo or more, because you know there is already those autos getting ready for you. And believe me, that Six Shooter was one of the nicest strains I grew so far, very nice high, body and head. It yielded about 60 grams dry per plant in 2 and a half months and gave me time to keep the White Widows and Moby Dicks longer in vegging, so now they are yielding as I said about a kilo wet each. I liked this Six Shooter so much I grew another one just to use it entirely for medical RSO.
