I expect that the UV contributed to the amount of trichomes. But I wonder if it also contributed to the amount of leaf.
Sometimes when I have to be outside all day in the middle of August, I'll throw a hat on top for extra protection, lol.
EDIT: Sir? SIR? Hey, just a minute now, I'm not THAT old yet. Well... Err... <GRUMBLE GRUMBLE>... I guess I'll just go for a walk, then. Now where'd my cane get to?
LOL
