Some crops dying while other are not

[Firestorm672]

So i am playing on a singleplayer game,it does have some mods but nothing that changes farming as far as i can tell, and i have basically set up a green house so i can grow stuff during the winter and not have to worry about my food. But i started to notice that when i plant something, some of them will get cold damage while others are fine. Mind you i know that different plants have different temp thresholds, but i decided to test with rye, since it can handle -12, and when i planted it, when the temperature outside was -12, it still took cold damage, while another rye next to it, that i planted at the same time was fine. This is in a green house, it has the green house buff and it is completely closed off, but it seems to still happen and i would love to know how to solve it.

Well, let me try my wits to explain this.

1. -10 outside at about 4 pm likely means around -18 at 4 am, so even accounting for the greenhouse, your rye will still suffer from cold damage. And crops cannot grow below 0, whether rye or pineapple, the threshold is just there to protect from cold damage, not from halting growth.

2. The difference could be due to the game simulating the temperature block by block or just some delay in the simulation(similarly, the greenhouse takes some time to validate every block's +5 temperature). With a long enough period, from my observation, every crop's growth will stunt under occasionally too low ambient temperature.

I'm going with the first.  Especially considering that there's 75% yield to the crops.  I'll bet that as winter progresses and there's more time the outside temp falls below -17 the yield will drop more.  While greenhouses will increase the ambient temp and extend the growing season, it doesn't mean that year-round farming in colder climates is possible.
