Columbine
Ground-to-Ground
The Columbine is a durable ground-to-ground house ideal for winter greenhouse protection, early spring starts, and
inexpensive greenhouse expansions. This freestanding structure is made of high-strength, 2-inch galvanized square
bows. It is competitively priced and easy to assemble. With up to 12′ peak height, many growers use Columbines for
multi-tier production with hanging baskets overhead and flats or containers below and along the sidewalls. Outfit the
Columbine with heat and mechanical ventilation or go passive with roll-up sidewalls and large double slider doors on the end walls.
