I started some of my plants on February 24 and the rest on the 27th. I planted Coleus, Purple Wave Petunias, Dianthus, Pampas grass, Impatiens, Moonflowers, Purple Prince Zinnias, and Victorian Mix Dahlias.
I covered the unit with thick plastic to create more of a green house effect. It really kept the temperature warmer and helped keep the plants from drying out so quickly.
I was shocked at how quickly things germinated, especially the coleus.
