I purchased a AeroGarden to start some Vegtables for the spring. The Vegs grew so quick that I was unable to plant outside since it is still to cold. I am thinking about starting a indoor flower garden for my hatchlings. Some of the flowers for the Aerogarden are, Geranium,Petunia,Marigold,Snapdragon,Lavender,and a few others. Which ones would seem better, and are there any to avoid?
