I’ve also never heard it that way before. I’ve always been told it’s the cold fall nights (you need the temp difference as well as the drop) to initiate a spike, and cool temps during flower to prevent bud blast.

Leigh, I’d be curious what the temps in your greenhouse were during winter if you remember? Also great call on the Aos Cym. Edition! I have a digital membership, so it’s always with me!

I’ll probably try a warm variety out because I suspect I’ll do fine with it. The reason I ask the question though is i’m majorly crushing on a particular variety I saw out west. Omg the flowers just glow. I suspect it’s probably a standard variety. The name on the tag was Koushu Mae and bred by Mukoyama in Japan but I can’t find any info on it and doesn’t seem to be registered. :,(
