Preparing and Maintaining Cold FramesI have installed Plastic Covered Cold Frames; they are to be electrically heated with lights beneath the plastic covered lids.
The Cold Frames require spring maintenance (repairing & replacing some of the plastic covers) and preparing the cold frames for plants (cleaning the inside of the cold frames, running the electric line to the cold frame area, stringing the heating lights inside the cold frames, placing the repaired covers on the cold frames and lastly we turn on the lights to thaw and heat the inside of the cold frame planting areas). In about 7 to 10 days the cold frames will be ready to receive and protect our new potted plants until early June; when we will relocate the plants in their peat pots to the produce fields.
Thus we will be able to have a Superior Lake growing season of 120+ days.
The Cold Frames area is shown below.
