      Essential Interior Greenhouse Systems & Supplies

      The right interior greenhouse systems help create a controlled, efficient growing environment that supports healthy plants and simplifies daily operations. From organization and climate control to lighting and irrigation, these essential components allow growers to maximize space, conserve resources, and maintain consistent growing conditions year-round.

      • Grow Benches & Tables: Elevate plants with grow benches or tables for better airflow, drainage, and organization while improving ergonomics and making daily tasks easier and more efficient.
      • Irrigation & Watering Systems: Irrigation and water systems deliver consistent water and nutrients directly to plants, reducing waste, improving plant health, and saving time through automation.
      • Grow Lights: Supplement or replace natural sunlight with grow lights to support seedlings, cuttings, and light-sensitive crops, extending growing seasons and improving uniform growth.
      • Climate & Environmental Controls: Fans, heaters, vents, and controllers regulate temperature, humidity, and airflow, helping prevent plant stress, disease, and uneven growth.
      • Shading Materials: Manage light levels, reduce heat buildup, and retain warmth when needed with shading materials, improving energy efficiency and protecting plants from extreme conditions.
      • Automation & Monitoring Systems: Timers and controllers automate key processes like watering, lighting, and ventilation, ensuring consistency while reducing labor and guesswork.

      Interior Greenhouse Systems FAQs

      What are interior greenhouse systems?

      Interior greenhouse systems include the equipment and supplies used inside a greenhouse, such as benches, irrigation, lighting, and climate controls that help create an optimal growing environment.

      Do I need interior systems for a small or hobby greenhouse?

      Yes. Even small greenhouses benefit from basic interior systems like benches, fans, and simple irrigation, which improve plant health, organization, and ease of maintenance.

      Can interior greenhouse systems be added later?

      Most interior systems are modular and can be added or upgraded over time as your growing needs expand.

      Which interior systems are most important to start with?

      Grow benches, proper watering systems, and basic airflow or ventilation are typically the most essential for healthy plant growth.

      How do interior systems improve greenhouse efficiency?

      They help regulate temperature, light, water, and airflow more consistently, reducing plant stress, conserving resources, and saving time through automation.

      Evaluation of Products & Systems

      Your greenhouse performance goes far beyond the consideration of size, power, and the foundation. Additional aspects include:

      • Glazing Materials - Roof and wall systems including poly and plastic film, polycarbonate sheets will have varying impacts to efficiency (temperature and climate), cost (both initial and maintenance), light diffusion, and piece of mind on span of life for the materials and the structure as a whole. We can work with you in understanding the best fit for your project.
      • Doors - Insulated, blackout, automatic, and more. We offer a wide selection of doors with recommendations to meet your needs, including framing and install.
      • Ventilation - Ventilation plays a key role in managing the environment within your structure and can often be done in a manageable way from a cost perspective:
        • Adding roof vents can be a great approach for heat and humidity removal with minimal cost.
        • Gutter roof vents are the highest demand we see and named as such because they will close on the gutter.
        • Raised roof vents offer more ventilation on certain structure sizing. 
        • Roll up walls may be placed on any external or internal partition sidewall and can be manually or motor operated with a controller for full automation.
        • Guillotine/Vertical vents offer an alternative to roll up walls with added rigidity and a better seal in cold seasons.
        • Shutters can be an inexpensive way to add an area for air intake but. 
      • Mechanical Cooling - Natural ventilation may not provide quite enough for reducing the heat load inside a greenhouse.
        • In warmer, drier environments, evaporative cooling systems (which work by water being distributed over cooling pads while exhaust fans pull air through the structure) may be recommended. Intake equipment may include shutters, vents, and exhaust fans.
      • Heating - Defining the minimum allowable internal temperature will help determine the supplemental heat requirements for the structure, including back up heating considerations.
      • Benches - Rolling benches increase production space compared to stationary benches by eliminating walkways. We offer a number of different options for the bench tops including expanded metal tops, plastic tops, wire mesh, and more.
      • Curtains - Curtains offer a solution which can help with shade considerations, heat and energy savings, and any blackout needs depending on the crops in question.
      • Lighting - The type of light needed and the technology to support will vary from the intent. Some types of lighting, like High Pressure Sodium, may offer lower upfront costs and some additional heat but, as an older technology, may have higher long-term costs for upkeep/power. Light Emitting Diode (LED) offers different spectrum options with less heat and lower operating costs.
