First Snow on the Greenhouse

First snow on the new greenhouse this morning! Thought it might melt off by mid-day but its still hanging on. Mid to high 30’s outside and around 50 in the greenhouse. Watered the spinach. Not sure if that was the right move or not in light of the cold, but I guess we’ll find out. Supposed to be coldest night of the season tonight, high teens low 20’s, then get warmer later into the week. Spinach looks good but I’m questioning the estimations of how much it will produce. Its just not looking like 900 lbs is going to come out of it.
