More about this product



In conjunction with our cost-effective yet sturdy exterior auto light dep system, Fullbloom provides one of the best internal auto light deprivation systems in the industry. Our Guardian Series engineered blackout greenhouse is ideal for high snow, high wind areas or anyone requiring a coded/engineered structure. This 35’ wide semi-gable structure makes it easy to grow year-round in most of the harshest climates in the US.


The Guardian is built with North American made hot dipped galvanized steel framing that is a semi-gable style greenhouse. Oval tubing bows and 2×4” uprights provide superior strength and defense against harsh weather. Sitting with an average peak height of 18’ and a sidewall height of 7’, the Guardian Series engineered greenhouse provides ample room for cultivation of any kind. Our pre-welded cathedral style truss system provides a strong structure that can withstand high snow and wind loads without sacrificing height.

Our pre-welded cathedral style roof support system enables us to achieve the highest snow and wind ratings of this style of greenhouse without sacrificing head height or adding unnecessary components that increase costs.

All of our frames and materials are pre-fabricated and punched so our customers save money on install costs. This makes it easy for you to modify and add additional equipment as it fits your needs.

Greenhouse growing these days isn’t complete without a light deprivation system. By using an automated blackout system, growers can harvest 3-5 times a year by putting the sun on their schedule. By harnessing the sun in a temperature and humidity controlled environment, growers will see their outdoor plants now producing indoor quality flower. Investing in a fully automated light deprivation greenhouse is a cost effective and efficient way to set up a climate controlled grow, while reducing start up costs and carbon footprints. Our light deprivation greenhouses are quick and easy to install and gives growers the control they need to have a successful harvest multiple times a year. Use the automated controls to set your blackout periods and your environmental controls and forget the headache of remembering to pull tarps everyday.


The precise control of your plants’ photoperiods is vital to their success. Inadvertently letting light in during their dark periods can cause problems with your crops and ultimately cost you money.

This interior blackout system will give you years of worry-free operation. Not all black out systems are created equally. This is a “pull-pull” cable driven system which provides a better light-tight seal. A patented sealing extrusion creates a tighter blackout when closed. The precision system opens up into tight bundles to maximize the amount of light that reaches each bay. The manufacturer rates it for more than ten years of maintenance-free operation due to the high tension and consistent seal.

Longevity and wear and tear is also an issue on most interior blackout systems. Most systems have issues with blackout fabric rubbing and eventually tearing as it is pushed and pulled across metal and/or cables. Our system uses specialized hook and lever system that essentially keeps the curtains free and clear so many years of use can be had before replacement is necessary.

Every portion of the system comes pre-fabricated with pre-installed connection points for easy installation by a professional contactor.

The three-phase Ridder gearbox motor arrives pre-wired with a reverse function and a manual operating switch. You can easily connect this to any environmental/automation controller. It has a variable frequency drive (VFD) for long-lasting reliability and performance.

Options & upgrades

Custom Design Automation Systems

Choose from our standard digital timer and thermostat package or fully automation your environmental controls with our custom designed, UL listed Link4 iGrow 800 Automation system. Comes standard with contactor/relay panel, 4 – 22 amp 3 contactor modules and NEMA 4 enclosure.

Double Poly Inflation Kit

There is no better insulation value then a double poly inflation kit. Using two layers of 6mil polyethylene and an inflation system, we create a deep air bubble, providing insulation for energy retention. You can inflate the full structure, or just the roof to allow for versitility in sidewall operation. This provides a 40% energy savings over polycarbonate and adds strength for wind and snow resistance.

Insect Screen

Cover your intakes with insect screen to prevent moths and other pests from entering the greenhouse. Reduces the need for insecticide use.

Odor Elimination

Tested and guaranteed odor elimination options for locations with strict odor laws. A fogging system is used on the exhaust fans and ridge vents with an additive that neutralizes 100% of all odors.

Grow Lights

Choose from a selection of the best grow lights specifically meant for Greenhouses. From IP7 waterproof LED’s to gold standard double ended HPS lights, and more. Fullbloom will help you choose the right grow lights for your greenhouse location and budget.

Fogging Systems

High pressure fogging systems by Fogco provide additional cooling and humidifying options for dry and high temp climates. Additionally the high pressure fog droplets encapsulate airborne molecules, causing dust particles to become heavy and fall from the air.


Essential for humid climates, choose from various size dehumidifiers to aid in properly maintaining ideal humidity for healthy plants. Allows for VPD control, limits powdery mildew outbreaks, and improves crop quality.

Evaporative Cooling

Significantly lower greenhouse temperatures with evaporative cooling. Used on the intake side of the greenhouse, our evaporative cooling systems use cold water to cool down air as it’s drawn through the pads, bringing coller air through the greenhouse. Additionally, evaporative cooling systems help to neutralize pollen and outside contaminates.

Natural Gas & Propane Heating

Maintaining a uniform environment is essential to growing healthy plants. Utilize the industry best Reznor propane or natural gas heaters to automatically heat greenhouse as needed. Overhead heaters will help with controlling VPD levels, so you can maintain an ideal growing environment in any climate.

High-end Exhaust Fans

We offer the industry’s best quality US & Dutch made exhaust fans to ensure you always have proper airflow and can cool your plants in the heat of the summer. Choose from budget friendly and highly efficient options depending on the size of your structure and project location. Our fans are designed for efficiency and operate at a higher CFM for better air exchange and optimized use of energy. Exhaust Fans and Intakes are packaged with light traps to prevent light leaks when operating while the greenhouse is dark.

Inflated Double Poly Insulation

Every grower in moderate to cold climates should consider an inflated roof package for greenhouse cultivation. Two layers of polyethylene are locked into place in the roof and blowers are added to create a bubble of air in the roof (with optional sidewall inflation). This provides the best energy saving of any covering, even the more expensive twinwall polycarbonate. 

Ventilation Equipment

Every greenhouse needs proper ventilation in order to remove hot air and humidity from the greenhouse. Fullbloom will look up your specific weather data and to provide the best options for ventilation, including exhaust fans, circulation fans, vertical V flow fans, intake louvers, light traps, and more. 

Evaporative Cooling Walls

Evaporative cooling walls harness the natural process of evaporation to significantly lower temperatures within the greenhouse. By saturating absorbent pads with water and and using negative air pressure with exhaust fans, temperatures can see 10-20 degree drops. Ideal for most growers in high heat climates

Twinwall Polycarbonate Side Walls

Polycarbonate siding is essential for extreme cold climates where snow shed from the greenhouse can put pressure on the main greenhouse frame, and provides for significantly more heat retention than a standard soft polyethylene. Pairs well with a ridge vent for passive air removal.

Automated Ridge Vents

Automated ridge vents are one of the best methods of passively controlling your  greenhouse climate. Our extra large 4’ ridge vent allows for hot air and humidity to naturally rise out of the greenhouse, putting less pressure on the ventilation equipment and keeping your electrical bill lower. Paired well with our V-flow fans that help push air vertically through the roof.

High Pressure Fogging & Odor Mitigation

High pressure fogging systems further help with cooling down a greenhouse as atomized water flash evaporates above the plant canopy, producing cooler temperatures. Generally paired with an evaporation cooling wall in extreme heat & dry climates, fogging can also help with pest prevention and the spreading of pollen. Additionally, full odor mitigation options are available cultivators dealing with odor mitigation laws.

Automation Systems

Choose from standard thermostat controls to fully automated environmental controls like our standard Link4 & Climate Boss automation systems. These systems work seamlessly with all your greenhouse components to maintain temperature, humidity, and proper airflow. Available with pre built power panels, humidity sensors, weather stations, and much more. Fullbloom has your automation covered.
