Interesting Maritimer! I've had several go only 4 days I'm pretty sure. I was thinking soil tilth, room rh, temp, fan breeze, and pot size before you mentioned light source. Because the plant gave me the reaction I was looking for, I fluffed it off. You think the plant didn't react as it indicated by its leaf angle?Caplan was in HPS for his studies. Is this a Key for longer duration droughts?
