You can take a browse through my grow log, I have loads of photos if you are curious.

I would allow for about 3x their growth for flower. I think White Widows respond well to supercropping, so if you get yourself into a bind with space in the first few weeks of flower (when you see the truly insane rate of growth) you can bend the stem over and they tolerate the cruelty for it. They are good plants. :jointsmile:
how much vertical growth can you "cancel" out so to speak by bending them over? 6-7 inches probably?

White Widow Height Discussion Never grown WW before... my ceilings are 7.75 feet tall, but due to the resi, light, space in between lights, tables etc I only have 3.25-3.5 feet of available vertical growth. Have you grown WW that small and how was your yield? I am looking for 1 pound per 4X4 area, under 1000 watt lamps. I have been told they double in height during flower and get a bit branchy... seems from researching on the net that's one of two of the Phenotypes - the other being one cola short compact plants.
