Sounds amazing. I've got 100 degree difference between winter summer. 108 today 0-10f February. short session. Wild temperature swingshaha... I thought you meant the buds were 40"... OK, so 40" tall auto plants... 3.3ft.
Our typical season is year round ... plants will flower year round, because our night length is never less than about 10.5 hours. Most cannabis will start flowering at 10-10.5 hours of night. I grow in greenhouses, and my veg house is on "night interruption" lighting, to control flowering... works great.
