But temperature is no entirely enough. A year ago I had pines in 3 different senerios simultaneuosly. I stored some timbers in my 3 walled shop, that got no sun, with 1" stickers We were having single digit to 20's degrees temps. I thought this would be ok. Forgot about them for 2 weeks. holy moly. Fir no problem. Heartwood on pine no so bad, sap yes. One box-heart pine sap all around even had crazy red streaks in it. Once moved stickered with good air flow the problem stopped.
