Excellent. I'd like to benefit from your research / experiences with the initiator lights, (never used them) , but curious about them. Do you think they'd be useful in a small outdoor backyard application? Were they beneficial indoors?
As far as initiating flower outside faster, I'm sometimes working in the opposite direction at about 44* north. I've got some that might flower too quickly (probably genetics causing this).
Trying to keep the quick to flower girls (M.O.B., Iranian and Iranian dominant crosses) in veg until after the solstice and prevent the dreaded "half flowering / half vegging" thing or outright flowering too early before the plants gains any size. Problem is, it takes up a lot of space and creates heat to veg them inside. So I'm considering putting them outside soon and using supplemental lighting for the next month for a few hours to prevent them from flowering right off.
As far as initiating flowering early, since the light dep thing may not work for me, my plan was to let genetics be my savior and go heavy on Iranian crosses to get some early finishers. Had some success with getting some C99 X Iranian crosses to finish in early September last year, so I've popped more from the same seed run, hoping for a repeat. I'm a pollen chucker and get lucky sometimes. They veg outside under normal sunlight pretty well until about the 4th of July when they started flowering like crazy, but don't finish real big, (nice 5-8 ounce back yarders) .
Your feedback on the initiator lights may have me considering using them for some normal photo period plants outdoors.
