Trust me, we will be fine. Healthy plants will take a beating before they show signs of stress. If your plants are not healthy well thats another story.im in maine. cold has turned my buds purplish. only about 5 weeks flowering kinda worried wont be able to finish.
Don't feel bad. I lost about 2 and a half pounds last year to mold.i love the cold weather.. it just reminds me that im that much loser to harvest!
40F nights are FINE!!! nothing wrong with it, just keep an eye on condensation build up in the AM because it could lead to bud rot, and thats how i lost probably a 1/4 oz last year
41.3 lattitude here
