This year I purchased a couple of inexpensive metal shelves from Ikea and started my seeds in my craft room. My craft room has a large, Southern facing window and is the warmest room in the house. The seeds came up in only 3 days. #itchingforSpring
I planted Broccoli and onion seeds and set them on a shelf in front of a Southern facing window.
Here are the metal shelves from Ikea. They were $14.99 and easy to put together.
