I made a cold frame Sunday from a 2ft x 3ft window section that I saved when a replacement was installed.
It’s a small, low cold frame, but very sufficient in size to hold big seedling tray. It’s about 12 inches high at the rear and about 9 inches high at the front. I set it facing the south on one of my garden beds.
I planted 72 peat pellets today at lunch time. 60 were more broccoli, plus 6 arugula and 6 “green ice” lettuce. I put the tray out in the cold frame to see if they’ll grow for me outdoors.
We’re currently having a warm spell, but our average last frost date is April 21. We’ll see what the next 5 weeks bring for these seeds.
