A friend of mine got some of that high-end "afghani couchlock" type
dope and found two or three mature seeds, presumably fertilized by a
male flower on a hermaphrodite plant. He sprouted one of the seeds
and has been growing it under a mix of fluoros and modified HID yard
lights, including a 175 watt mercury vapor lamp top and center.
I just posted a picture of the plant in alt.binaries.pictures.misc.
The picture was taken last night just before it was pruned for the bud
cycle, seven weeks to the day after it sprouted. It had reached a
height of about 39 inches. The leaf itself is pretty reasonable
smoke. Notice the dark bluish tint to the leaves from the MV lamp.
