Gardening
Growing food indoors in Denver, where the outdoor season is short and the air is dry.
What I grow
Indoors, year round: herbs, greens, and whatever else survives a hydroponic setup and my attention span. I restarted the whole thing after letting it lapse, and wrote about why.
Outdoors it is zone 5b, which means a late last frost, a short summer, and seeds started inside in February if they are going to amount to anything.
