Nice looking lady!
Mine are only around 12 inches tall at this point, but I topped them pretty early. Their first 3 months they sat in the window of a spare bedroom and didn't get any light other than through the window. After that I put them on 24 hour CFLs for about three weeks and switched to 12/12 21 days ago. Actually, they've had a pretty rough life when I think about it. I planted 6 germinated seeds in one pot and sat it in that spare bedroom. I only watered them once a week or so, and when i decided to transplant, I had to basically wash all of the dirt away because the roots were tangled. I put each one in their own pot and learned a valuable lesson, but unfortunately, the pots were a bit small. So, I waited to sex them, scrapped the males, and transplanted once again. I also topped them in week 2 of veg under the CFLs, took several cuttings for clones at day 14 of flowering, and have trimmed a couple of fan leaves to allow more light to reach the bud sites a few times during flowering.
