The external light deprivation system included in this kit performs better than any other roll to peak blackout system on the market. Our blackout system utilizes entirely custom components to ensure total blackout in mild to moderate conditions. With 3” aluminum roller bars, dual weather resistant high end motors, custom mounting brackets and a vertical climb system, our external blackout system is unmatched by any other roll to peak blackout system on the market.

With a center peak height of approximately 17’ and standard sidewall heights at 7’ (may differ depending on engineering requirements) cultivators have plenty of height to grow tall flowering plants on the ground or on benches.

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.

Options & Upgrades:

Winter Inflation Kit

There is no better insulation value then a winter 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.

Grow Lights

Use the right lights for your climate, growing goals, and budget. We help guide you through the process of choosing lights and ideal placement. Choose from energy efficient LED’s, LEC’s, and high power HPS lights. All tested and vetted for greenhouse efficacy and results.

Auto Roll Up Sides

Auto Roll up sides provide a great solution for heat removal and passive airflow. When the air outside the greenhouse is a better temperature than inside, the sidewall roll ups will open and improve climate conditions without relying on ventilation equipment. Available with anti insect netting.

Polycarbonate End Walls

In extreme climates, polycarbonate end walls can have the benefit of added strength and energy retention. We use 8mm White/Black/White polycarbonate for the end wall cladding to provide blacked out end walls with better IR value than sheet metal or polyethylene.

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 neutralizes pollen and other contaminants to keep the greenhouse disease free.


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

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.

Insect Screen

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

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.

V-Flow Vertical Fans

Combined with horizontal airflow fans, V-flow fans by Vostermans creates the ideal solution for heat distribution throughout the greenhouse. Pulls warmer air from above the plant canopy and redistributes air for more consistent temperatures.

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 its drawn through the greenhouse. Evaporative cooling systems additionally neutralize pollen and outside contaminates.

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.
