Hobby Greenhouse Gardening: Extend Your Growing Season

For gardeners in short-season climates, a hobby greenhouse transforms possibilities—providing fresh tomatoes, greens, and seedlings months before outdoor conditions allow. Not commercial-scale, but perfectly sized for personal abundance.

Community and Resources

The Hobby Greenhouse Association publishes a quarterly magazine, sponsors events, and connects enthusiasts with specialized interests—cacti, seed saving, orchids, and more.
