Wait a minute! I haven't esplained myself yet. :)
I don't know why you would want to do this and you may have created a special way of doing it but if the average grower tries this I can't imagine it turning out well. I like to experiment as well but what is the purpose of doing this?
The very specific purposes are two-fold. First, it means that you don't have to stay married to a photoperiod like 18/6 (insert photoperiod of choice). But the much more important reason is because I will grow outdoors for as long as I'm physically able. However, I don't just grow seed starts, very often I will have something from the previous year that I really want to run again, so I keep cuts that will go out that following spring.
Cuttings--how to grow them
indoors in a manner that will (hopefully?) ensure that they don't immediately go into flower when they're placed outdoors? Interrupted photoperiod. That means interrupting the DARK cycle.
The daylight cycle is set to match the daylight hours of my location on the date I plan to set them out. Where I am that's usually about 13hrs daylight. Well, you may already know that if you just put them on 13hrs daylight most all strains will begin to flower out, right? NOT if you interrupt the dark cycle.
So, I do it so I can put cuts outside and they won't immediately flip into flower, thusly stunting not only that important vegetative growth (I need them to get some height and breadth to them before they flower), but reducing or eliminating the risk of that photoperiod confusion that occurs when they begin to flower, and then go back to veg because the daylight hours are still lengthening.
So far I've only had one strain refuse to go into full vegetative state, that wants to flower--Blockhead.
