Altitiude: No these are photo-period. I had the mother on 24 hrs for 2 years she loved vegging all day. Heres my old journal of that:
JblJakes Indoor Top Skunk 44 March 2013
I got these feminized seeds from Attitude. Search for Top Skunk 44
Also: I selected this strain for its quick flowering properties. The 44 is supposed to stand for 44 days of flower but I let them go as long as I could.
I'm finding it helps a lot to get the clones a good start inside then bring them out as soon as you can (after last frost). These were also placed in an area with decent south sun for more light during the flowing.
This diagram sort of explains my thinking...
