Ur plant is incredibly tall. I trimmed mine constantly because I wanted a bushy plant plus mine is indica "Mr. Clean" All I have is a 250w halide. The pictures are from when I started flowering on 1-5-12. My plant is 2 and a half feet tall but 4 feet wide. My grow space is 4x4x8 in the garage and i live in Seattle so my grow room stays about 70 degrees. If the temperature is constant thats ok. It only showed stress under 60degrees. I really notice that using the proper nutrients is key. Light and fertilizer. I think your plant is Sativa, mostly because it grew so tall and skinny, but it's only a geuss. The picture of that little one is a seed "Orange Crush" that i germinated and is next on the list.
im about to put my baby away for 48 hours of darkness to dry out in its bucket but ive noticed by cuttin a plant straight away and then drying it out only leads to amouthfull of either chloryphil or some type of manky copper taste lol
