Fullbloom Semi-Gable Greenhouse

Our Fullbloom Greenhouse packages make greenhouse growing hassle-free and economical by using best-in-class galvanized steel framing, anti-drip and light-diffusing poly, and only the best ventilation and automation options. We designed our framing to be as simple as possible to install, eliminating thousands in potential labor costs from our competitors’ frames. We use the toughest and thickest galvanized steel frames in the industry so your greenhouses last longer and are more resilient in tough weather. All of our accessories, such as our exhaust fans, are US-made and UL-listed for easy permitting. Last but not least, we provide the lowest cost possible by limiting unnecessary features and streamlining our designs, passing the savings and simplicity on to the customer.

Making the switch from outdoor (or indoor) growing to greenhouses makes more sense than any other growing style. By limiting exposure to rain, snow, humidity, pests, excessive heat, and cold, the quality of the flowers produced is often comparable to any indoor garden. Outdoor growers can save thousands in expenses every month by harnessing the power of the sun. Indoor growers save tens of thousands on building and energy costs by utilizing natural light and lower equipment expenses.

Greenhouse Style:

The semi-gable greenhouse strikes a smart balance between function and simplicity. Its defining feature is a partially curved roof combined with straight sidewalls. This design offers more usable vertical space along the walls, making it ideal for trellised crops or tall shelving. Unlike fully curved or peaked greenhouses, the semi-gable shape allows for consistent airflow, better temperature regulation, and solid structural performance—especially under snow or wind pressure.

This structure isn’t just about looks. The semi-gable design reduces heat buildup at the peak while still allowing for efficient ventilation. It also makes the most of natural light by maintaining optimal angles throughout the day. Whether you’re a commercial grower or running a smaller-scale operation, the layout supports productivity and comfort without the drawbacks of overly steep or completely rounded designs.

Automate Your Way

A year-round semi-gable greenhouse takes everything good about the design and supercharges it. Add automated ventilation, evaporative cooling, heating, and smart controls, and you’ve got a setup that can thrive in blazing summers or freezing winters. With the right system, the internal climate adapts hour by hour—without you lifting a finger. These greenhouses are built for growers who want consistency and control without babysitting the thermostat. Whether you’re growing leafy greens in Montana or tropical plants in Texas, this style delivers stable growing conditions and peace of mind.
