The pro’s Short lifecycle and a quicker Harvest More flowering cycles during the year Your plants will be small and compact No change in photoperiod needed. The plant will enter the flowering stage “automatically” (more info below on that). This can be helpful especially for outdoor growers. Since these are OGM seeds they generally have better resistance to issues, whether this is heat, cold, nutrient burn, etc The con’s Smaller plants (a pro for some, con to others). Lower handle on the length of the vegetative stage. Much harder to control when the flowering stage starts. Lighting: Since you don’t have to change the lighting from 16/8 to 12/12, you can keep 16hours of light, increasing your electric bill. Generally auto flowering plants yield less buds. Generally, they also have less THC content than other strains. Globally, if you’re growing indoor i’d stick with non auto-flowering seeds, switching the timer to 12/12 once you want to get your flowering stage going isn’t that hard. I’m personally regretting doing these right now, all though it allows us to learn about them.
