g'day,
I have recently read a scientific paper on hormone response to phytochromic adjustment.
or in layman's terms changing light cycle from 18/6 to 12/12 to initiate flowering in photoperiod cannabis plants.
which is standard practice for indoor growers .
the thesis basically postulated that the same could be done for outdoor plants,
-( which we see in greenhouses that have an automatic 12 hour darkness period built into the roofs of the greenhouse, to allow for several harvests per year)
BUT
the authors stipulated that building a nursery and giving the 1 month old (and 40cm high) cannabis plants (using REGULAR seed) an un-interrupted 12 hours of darkness for 10 - 14 days could sex all the 1 month old plants, and then repot just the females into larger 200L pots in all day natural (summer) sunlight, thereby reverting the 6 week old and 0.5 meter tall ( and artificially sexed plants) back into the veg cycle.
HAS ANYONE done this and could speak to the results they experienced from the exercise?

PS. there was also another OUTDOOR light manipulation experiment that, allowed the farmer to keep the plants in the vegetative state for an extended period of time, (whereby by being able to increase yields exponentially), which also gave the farmer the ability to nominate when the plants flowered and were harvested.
COULD ANYONE tell me if they had used this technique either?!?!??
