We have had another round of cold nights in the low 20’s and teens. Since our greenhouse is not yet heated its been a struggle to keep things from freezing. But the spinach has not only survived but seems super happy! This is the spinach we planted back in August of 2022 and have been eating and sharing with neighbors since September! We pick off the bigger leaves and let the younger leaves grow. Pick… Eat.. Repeat!! We had lettuce in that back tank but it was harder to keep it happy in the low temps and I think it plain lived out its lifespan. I removed all the lettuce from that tank and moved the spinach over from the other tank to consolidate and make it easier to keep warm on nights below freezing.
I had some rigid foam for future hydroponic tanks that I used to create a warm box to protect the spinach during the night. Added a heat lamp in to keep it above freezing. It’s not ideal but it worked in a pinch! Our 10 day forecast is back to normal Pacific Northwest mild rain.. Spring is coming soon!
