Indeed it is an important subject. We're having a very warm fall, but we did have one night that dropped to -2 C (per weather station). It killed every tomato plant in the farm greenhouse, brown stick dead! Many of the outdoor crops are still standing tall and doing fine - even the lettuce (granted it is in the lower field so may be microclimate differences too). So it did make me think of this thread. We naturally expect a few degrees extra warmth in the tunnel but it can be the opposite on those frosty nights!
Forgot to mention, it was quite dry and minimal watering the past month in the tunnel. So opposite of your water strategy, Cole.
