that's what I thought del... , I don't what the fuck Harddon is talking about. Anyhow as far as how the plant knows what time of year it is, I just started reading a book called "Supernature" (by Lyall Watson). The book talks alot about "circadian" rythms and how lots of species in nature rely on them. I think it's an instictive behaviour that the plant just knows from experiance
