Fast Flowering Explained

This is from an email I got from North Atlantic. They may be a good choice to grow outside in Maine. I dont know

FAST seeds-

• • A FAST strain is a photoperiod strain, meaning that it is photo-sensitive and it does require the grower to peel back the light-per-day in order to flower.  FAST strains tend to be extra photo-sensitive and will trigger to flower easier, with more light per day, than a normal photoperiod plant would. They are great plants to run outdoors because they finish weeks earlier than normal photoperiod strains finish; however, it is critical that you wait until mid-June to put them out. If you put them out earlier, there will not be enough light per day for them to stay in a vegetative state and they will likely pre-flower. Indoors, we recommend a 24/0 hour light cycle in the vegetative phase and a normal 12/12 schedule for the flowering phase. 

• • Genetically, a FAST strain is a first generation (F1 or R1) cross of a photoperiod plant with an autoflowering plant. This practice promotes a FAST finishing genetic trait. In understanding the science of genetics and breeding, we know that the autoflowering trait is recessive, meaning that in a first generation cross of photoperiod x autoflower, the autoflowering trait will not be present (0% likelihood, genetically). In an F2 cross, you would see the autoflowering trait exhibited 25% of the time, and so forth. FAST strains are F1 only, so they do not autoflower. Instead, the autoflowering genetics lend to a faster flower and a more photo-sensitive genetic makeup. It can be expected that a FAST strain will finish at least 1-2 weeks earlier than the standard photoperiod counterpart, and often close to a month earlier if grown outdoors.
