Investing in a fully automated light deprivation greenhouse proves cost-effective and efficient, establishing a climate-controlled growing environment while reducing startup costs and carbon footprints. Quick and easy to install, our light deprivation greenhouses offer growers the control needed for successful multiple harvests without the daily hassle of manually pulling tarps.



 Ensuring precise control over your plants’ photoperiods is crucial for their optimal growth. Any unintended light exposure during their dark periods can lead to issues with your crops, translating into potential financial losses.

Our interior blackout system is engineered to provide years of worry-free operation, setting it apart from others in the market. Utilizing a “pull-pull” cable-driven mechanism, this system ensures a superior light-tight seal. The incorporation of a patented sealing extrusion enhances blackout efficiency when closed, while the precision system allows for a tight bundle formation, maximizing the light reaching the plant canopy. With a manufacturer-rated lifespan of over ten years, this system guarantees maintenance-free operation due to its high tension and consistent sealing.

Addressing the common concern of longevity and wear and tear, our blackout system stands out. Unlike most systems that encounter issues with fabric wear due to friction with metal and cables, our specialized hook and lever system keeps the curtains free and clear. This design ensures that the system can be used for many years before replacement becomes necessary.

Automated Ridge Vents

All of our interior light deprivation greenhouses come with the option for a manual or automated ridge vent. Usually around 6’ wide and spanning the length of the greenhouse, a ridge vent is a great way to passively remove heat and humidity build up. It’s an ideal solution for hot climates to help reduce energy costs from active cooling through ventilation.

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.

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. 

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. 

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.
