Pink autoflowers

If this strain is genetically dominant and stable for pink colouration of the flowers, it should do so without the need for you to do anything. Sometimes, when you look further into the breeders notes on the strain, some will say pink/red colours are in only 70-80% of the mature plants, which then means it becomes a matter of luck as to whether you get a pink/red flowering plant. The colouration is only a cosmetic feature and does not increase potency, yield or vigor in any way. Another thing that can affect plant/flower colour is when night temperatures are 10-15 degrees Celsius lower during the night than they are during the day or "lights on" period. However, this is a different process and is caused by an accumalation of anthocyanins, a naturally occurring plant pigment, but this usually presents as a dark purple effect by the time the plants are fully matured. Anyway, if your strain has the genetics to produce pink flowers, it should do this all on its own, like I said earlier, without you having to do anything and usually any colouration starts to appear about half way through flowering and rarely right from the beginning. Hope this helps, Organoman.
