Want to start your growing season early? Maybe extend in into the winter months? Then build a cold frame or sometimes called a mini greenhouse. A cold frame is 4 walls that secure heat and protect plants from the elements and a top that allows light through.
Step 1) Find a good location that gets lots of sunlight and faces south.
Step 2) Build the walls. I used straw bales. They’re great at holding in heat and no tools are needed.
Step 3) Use some old windows to put on top. I used some storm windows I found in the trash at a local church.
Step 4) Fill with plant trays full of seeds.
Step 5) Keep an eye on temperature, moisture and airflow. Open up the lid a few inches to circulate fresh air in.
Step 6) Acclimate your seedlings by taking the lid off when they get bigger.
