One side of the hoophouse is full.  In the pic, from front to back are lettuces (Forellenschluss, Black Seeded Simpson, Buttercrunch, and Red Salad Bowl), and scallions (Purplette, Pearl Drop, and Evergreen).  At the end on the left are three trays of lettuces that have just been seeded.  Behind us are 4 trays of broccoli (Tendergreen and Green King), and a few more trays of lettuces that are halfway between the two rounds you can see here.

During the day, the house gets pretty warm, so we ventilate by opening the ends and rolling up the side.  At night, it still gets cold (tending toward high 20’s on most nights).  So we cover the plants with an extra layer, as shown below.  This traps just that little bit of extra warmth that keeps the plants happy.
