Three 'Black Cherry' tomato plants I plan on growing as long as I can into the Fall & Winter in the unheated greenhouse. As they get taller, I can remove the shelf they're sitting on so they're not smooshed up against the greenhouse wall.
I bought three 50-quart clear storage bins (Mainstays brand, Walmart) and then three 1-cubic foot bags of potting soil, Miracle Grow. The cover of the bin acts as a tray to catch water. I poked holes on the back side of the bag of soil, then laid it on the tray and cut out the top of the bag. I will direct-seed salad greens into the soil and water. Cover with the 'bottom' of the tub to act as a mini-greenhouse until the seeds germinate, then off during the day and on at night. This SHOULD extend my growing season in the unheated greenhouse.
