The Thoreau GROWERS Greenhouse Package is designed for growers looking for a professional structure to grow their crops of choice in an ideal controlled environment.

Constructed with a sturdy 2" x 2" galvanized steel frame featuring pre-welded stanchions, this greenhouse uses commercial-grade 8mm twin-wall corrugated panels for both walls and roof—matching the quality found in top commercial models. The durable walls and roof come with a 10-year warranty and are designed to last 15 to 20 years. With 6-foot-tall walls and a 9.5-foot center peak, the Thoreau greenhouse ensures excellent air circulation, creating an ideal environment for healthy plant growth.

The GROWER greenhouse is thoughtfully designed with features tailored specifically for serious growers, setting it apart from hobby or commercial models. It boasts an exclusive 8mm twin-wall polycarbonate with light-diffusing technology, maximizing light absorption to enhance plant growth while reducing the need for supplemental lighting. Although some crops may still require up to 18 hours of light daily, this design helps save energy. The package also offers a secure, lockable space, durable construction for long-lasting use, and a climate-controlled environment with precise thermostat regulation to support optimal growing conditions year-round.

Our line is comprehensive in nature. We offer our customers the ability to choose from 8 sizes and designs for your specific needs. We understand the process and have simplified it for the consumer in complete package format at a budget price for a quality greenhouse.
