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. Anyhow, I can rip out the tables in there and set up a new irrigation system, but it would be easier this way... I need to decide within a few days. Tell me about your WW - where did you flower? Where did they end up? What was your yield? Lights? Thanks!!
