Yeah the cold defianly brings out the purple. But some plants will never turn purple, no matter how cold it gets. But I would say the purple does effect the buzz. Anthocyanin the chemical that turns the plants plays a big role. I have had a wedding cake grown in a greenhouse that is green during summer, but during winter it turns purple, and I really loved the purple one for a night time smoke. But TNH now a days I prefer the lower THC strains anyways. Defniatly need a lot of terps to go along with my THC. Happy new year!

Congrats on bany # 2. Do you know if it is a boy, or a girl yet?
