THC is not physically addictive
psychological dependence is a whole other issue (which can lead to physical effects)

sally does well under HPS
just keep the light far enough away
that chart shows the optimal range for cannabis, but i'd say it seems that 1000-2000foot candles is what you are looking for..
for a 250W, I'd say you want to be around 2.5ft away, maybe start off around 3 just to see, better to be a bit etiolated than crispy
I have some around a 600W and they do the best at around 4ish feet from the bulb or more but 6ft seems to be pushing it, at about 2-3ft they start to suffer from too much light, first with the thickening of the leaves and they can become very leathery and then they have deformed growth
this is nice growth though
but otherwise flouros work just great too, esp tubes, you can keep tuebs very close the the plants if they arent too hot, cfls have to be farther away, but both work very well, 2 4ft flouros bulbs will support plants under it if they are a few inches away, the whole length of the light if they dont start to get too bushy and away from the light tubes might be cheaper but a 250W HPS will be able to support a good amt of plants
