Greenhouses 101

DESIGN FOR YOUR CLIMATE

Note: These are general climate characteristics for regions of the U.S. This information is intended for initial greenhouse design. For best greenhouse performance, location specific data must be used.

PLACEMENT CONSIDERATIONS

OVERALL AESTHETICS

Even though any two greenhouses may be made of the same materials and have the same functionality, the aesthetics can be drastically different, as illustrated by the English and Contemporary greenhouses.

English

An English greenhouse is the epitome of traditionaly classic appearance. They are highly ornate yet functional and add charm to a home or business. English greenhouses may include decorative elements such as dormers, ridge cresting, finials, grids, masonry base walls, or raised panels. Pilasters, historically-designed gutters and Palladian arches also enhance the structure’s traditional appearance on the exterior. Crown moulding, bar caps in various profile options and decorative castings bring the same character into the interior space.

Contemporary

Unlike their decorative counterparts, contemporary greenhouses consist of large glass areas, clean lines and a linear format. Mullions are used to allow for long projections. The greenhouse’s finish can enhance the modern appearance. Popular choices include white, black, and clear anodized, which is often used in industrial settings. Stainless steel cladding can be applied directly to the aluminum frame as well. The interior of the greenhouse achieves a modern flare through the use of flat rafters and commercial grade accessories.

PERFORMANCE

Thermally-Enhanced Structures

The energy efficiency of your greenhouse can be greatly enhanced through the use of high-performance glazing and thermally-broken aluminum framing.

Thermal Break

A thermal break separates the aluminum and minimizes conductivity of heat and cold from the outside to the inside while ensuring the structure’s interior remains comfortable all year long. Solar Innovations^® offers two types of thermal break systems; Polyamide Strut and Pour and Debridge. In the first method, a polyamide strut is threaded into the cavity between two aluminum profiles and crimped into place. In the Pour and Debridge system, liquid polyurethane is poured into aluminum cavities that have been machined with an Azo-Brader, that allows for the polymer to mechanically lock in place. Both methods improve thermal efficiency by breaking the highly conductive properties of aluminum. Nonthermal aluminum frames should only be used for interior spaces or where thermal conductivity is not important.

FOUNDATIONS

While Solar Innovations^® does not provide the foundation, we do make recommendations based on the greenhouse’s use and structure type. Please consult your local code official for regulations.

Concrete Foundations

For greenhouses larger than 200 square feet, a concrete slab, continuous concrete footing, or a concrete block footing is required and should extend below the frost line. Concrete block footings should extend a minimum of six inches above grade. Embedding anchor bolts into concrete is the best way to tie down the structure. It is recommended that a waterproof compound be applied as a moisture barrier and surround the foundation with insulation panels.

FLOORING

Your greenhouse floor needs to be comfortable for the gardener, allow for drainage, and be sterile. A French drain can be used for drainage, but must be installed as the foundation is poured.

Concrete

Concrete can increase thermal mass storage and does not harbor mold or disease; however, it will require regular cleaning due to soil build up.

Tile

Tile is durable and easy to clean and offers many color and pattern options. Use slip resistant or textured tile to help prevent falls.

Pavers with gravel

Pavers are a great way to reduce costs and can be placed in footpaths for better footing while the gravel acts as a perfect drain for water.

Gravel

Gravel is the most economical choice and reduces the spread of mud and dust. However, the gravel may need to be replaced and weeds may sprout.

STRUCTURAL CONFIGURATIONS

Once you have decided upon the style of your greenhouse, it is helpful to determine the overall shape of your structure as you begin to design your greenhouse. There are six standard configurations but Solar Innovations^® will work with you to design whatever structure your plan requires.

Straight Eave, Double Pitch

Double pitch is a classic shape for greenhouses and is the most common configuration for free-standing units. It provides a uniform space that is tallest at the ridge. As you determine the roof pitch, keep in mind the surrounding structures, as well as the fact that each plane of the roof can employ a different pitch.

Straight Eave, Lean-To

A straight eave, lean-to design is the most common configuration for greenhouses attached to another structure. They tend to require a smaller investment of materials when compared to a double pitch, but can provide the same interior area. This configuration is an excellent option if you only have a small amount of space, though it works just as well over large spans along a building. An advantage to this shape is the solid rear wall, which can act as thermal storage for solar heat and a suitable place for shelves.

Curved Eave, Double Pitch

Reminiscent of wooden greenhouses of the past, a curved eave, double pitch configuration, exhibits a classic look, especially when adorned with decorative elements, such as finials and ridge cresting. The curve in the wall can begin high on the rafter to allow for taller interior elements, or low on the rafter for a more traditional look.

Curved Eave, Lean-To

Curved eave, lean-to structures have eaves that are curved and can evoke two distinct styles depending on how they are configured. Curves that begin high on the rafter tend to exhibit a more contemporary aesthetic while curves low on the rafter allow for a more traditional look.

Bull Nose End

This roof design includes a double-pitch section that tapers into a nose. It is also known as a conservatory nose or Victorian-style nose. The nose typically projects half the width of the structure with six to nine segments comprising the radial shape. This feature can be utilized as a lean-to or grouped on opposite sides, creating a stand-alone octagonal structure that resembles a gazebo.

Hip End

In a hip end structure, all sides of the roof slope downward to the walls, usually at a gentle pitch. A hip end is easily adapted to numerous design styles. The size of the structure is typically smaller than a comparably sized gable end greenhouse, which can correlate to lower heating and cooling costs. Hip end greenhouses can be attached to a building or constructed as freestanding units.

Dimension Definitions

STRUCTURAL ENHANCEMENTS

Structural enhancements can add architectural appeal to your greenhouse. These elements often reflect traditional greenhouse styles. The most commonly used units are lanterns and dormers. Both designs will enlarge the size of the greenhouse and help to create a distinct design.

Dormers

Dormers project from a sloped roof, interrupting the roof line with a double-pitch sub-structure. They typically begin at the ridge line or in the middle of the roof. Multiple dormers can be used along a long span or one on each pitch of the greenhouse.

Click here to see more photos of Greenhouses with Dormers

Lanterns

A lantern is located atop the roof and can span the entire length of the roof or occupy only a small section. It can feature a hip end, bull nose, or double pitch configuration. Vents can be incorporated for natural air circulation. Lanterns add a decorative element, and give English character to your greenhouse.

Entryways & Vestibules

An entryway or vestibule may act as an air-lock and reduces cold air from infiltrating the greenhouse. This can prevent cold shock to the plants closest to the door. An entryway or vestibule can also offer storage and increase energy efficiency.

GLAZING

Glazing choice plays a critical role in the performance of your greenhouse, and the selection is both location and design specific. Low-E coatings allow the sun’s rays to pass through the glass while reducing the amount of heat transfer. U-values measure the amount of heat transferred through glass. The lower the value, the better it insulates. The value for a typical single pane of glass starts around 6.0, whereas you can expect values of around 0.13 for insulated glass with Low-E coatings, stainless steel spacers, and argon infill. Solar Innovations^®’ sales designers will work with you to determine your best options.

Double and Triple Glazed Glass Specifications

Low-E Glazing

Cardinal Glass Industries

LoĒ²-272

LoĒ²-272 is the most common and has a very slight green tint and assists in regulating temperatures in a greenhouse, keeping it cooler in the summer and warmer in the winter.

LoĒ-180

LoĒ-180 is an ideal choice for greenhouses attempting to generate solar heat gain, particularly with cooling accessories. This glazing is popular for colder climates.

LoĒ³-340

LoĒ³-340 is used when a greenhouse needs to be shaded from intense direct sunlight, protecting delicate plants like orchids. A coating is applied to clear glass, which blocks the sun and causes a soft blue tint.

LoĒ-i89

This energy-saving fourth surface, coated glass can allow for double-pane windows to meet ENERGY STAR^® guidelines. LoĒ-i89 is applied to the indoor surface, preventing heat from escaping the room and lowering U-factors.

LoĒ²-366

LoĒ³-366 is the best insulation choice. It blocks 95% of the sun’s harmful UV rays, which helps preserve the color and composition of furnishings, draperies, and wall treatments.

Vitro Architectural Glass

Diffused Light Glazing

To protect fragile plants, like Bonsai trees and orchids, from direct sunlight, Solar Innovations^® offers diffused daylighting solutions.

Solera^®

With an opaque white appearance, Solera^® offers greatly increased energy efficiency, thermal comfort, and glare reduction while allowing diffused soft natural light into the space.

Lumira^® Aerogel

When Lumira^®, an aerogel-filled polycarbonate, is installed, thermal ratings are increased and light transmission is decreased. At the same time, glare and sound transmission are reduced.

Thermochromic

Thermochromic glazing is a self-tinting glass technology that darkens gradually when heated by direct sunlight.

Electrochromic

Electrochromic glazing changes between clear and tinted states with the flick of a switch, reducing glare and heat but requires a power source.

FINISHES

A painted finish is suitable for residential and light commercial projects. The finish will withstand exposure to the elements and is resistant to impact. Solar Innovations^® offers a wide variety of colors, but will also match any custom color. An anodized finish is best suited for commercial jobs, due to harsher use. Anodized finishes are also designed to withstand the corrosive effects of salt water.

Metal Cladding

Cladding can be added to the exterior of a greenhouse for aesthetic purposes. Copper and bronze claddings are popular additions to historically-styled greenhouses. Stainless steel cladding is appropriate for a modern greenhouse or coastal applications and will not corrode.

Maintenance

A greenhouse, like any other building, will require maintenance from time to time. The frame and glass will accumulate dust through the seasons, and will need to be removed. Solar Innovations^® does not recommend using harsh chemicals. A solution of water, vinegar, and dish detergent will work well to clean the glass and frame. The key is to remove any dirt build-up from the frame, which will prevent future maintenance issues. Operable window and vent tracks need to be cleaned and checked to maintain proper function. Always test your greenhouse accessories, including heating, cooling, shades, operable vents, and windows as a new season approaches. Motorized operations, such as ridge vents, will need occasional lubricating.

GABLE PEDIMENTS

Gable pediments, also referred to as Palladian arches, are added to the triangular gable on a glass structure. The most common designs include a half round arch, with rays extending from the arch. The radius and number of rays are all customized to the structure. Grid work can be used to simulate true pediments or mullions.

KNEE WALLS AND BASE PANELS

Knee Walls

Knee walls (base or pony walls) are typically between 30-36 inches tall and are a common feature in greenhouses. Applying a stone or brick veneer to a concrete knee wall is a cost-efficient way to achieve a classic look. Solar Innovations^® recommends insulating the knee wall to optimize energy efficiency.

Base Panels

Decorative base panels follow the Elizabethan form of raised grid design. We offer two standard models: a raised panel, featuring an elevated face that protrudes 1/2” from the panel base, and a smooth panel. Base panels add a classic, traditional look to structures and doors.

Base Wall Considerations

Base walls, or knee walls, can be integrated into a structure’s design to meet a desired appearance, but can also provide practical solutions to common problems. In areas where grass needs to be mowed nearby, the base wall will provide protection from mower-thrown projectiles. In areas where snow accumulates, the base wall will provide better thermal protection when snow is piled directly against the structure. Cost savings may also be associated with base walls as it reduces frame height and the glazing area. In all instances, a footed concrete slab should be constructed as the foundation. Solar Innovations^® recommends two standard heights, dependent upon how the structure will be used and its surroundings:

Ideal height when furniture is to be positioned against the wall and provides privacy when sitting. In greenhouses, the sun can dry out plant roots on pots on the floor near the walls. This height optimizes that protection. Also, many gardeners store items under perimeter benches. The base wall keeps them out of sight from the exterior.

Proper height when no furniture or greenhouse benches are to be positioned against the walls, but still provides some protection against projectiles and snow.

Base walls can be excluded when the maximum amount of daylight is desired and the structure is not in danger of projectiles and snow is not a concern.

WINDOWS

The use of operable windows will help to create cross ventilation and natural air flow, giving you more fresh air to enjoy on beautiful days.

Casement Windows

Casement windows hinge on the left or right and open like a book. They allow for more air circulation than awning windows and can be inswing or outswing.

Pivot Windows

Pivot windows function just like pivot doors and work well when the jamb is not a suitable location to hinge.

Awning Windows

An awning window is the most common type used for ventilation. The window is hinged at the top, cranks out, and can be left open during light rain showers.

Hopper Windows

A hopper window is an operable window typically used above a door or window to ventilate the greenhouse.

Tilt-Turn Windows

A tilt-turn window is a hybrid of a casement and hopper window with a single dual-operation handle.

Fixed Windows

Fixed windows do not operate and are appropriate for areas where the window is difficult to reach.

DOORS

Operable doors are an attractive and functional addition to a greenhouse. Our selection of terrace, French, and pivot doors can be opened so occupants can allow fresh air to enter when the weather is pleasant.

Terrace and French Doors

Terrace doors are single swing doors, while French doors are a set of two swinging doors that operate opposite one another. Units can be hinged left or right and swing in or out. Sizes are custom designed and are constructed of the same materials of the structure.

Pivot Doors

Pivot doors have a similar operation to swing doors but are not hinged at the jamb. The pivot points are located on the head and sill and can be placed anywhere along the width of the door. Multiple pivot doors can be installed directly next to each other.

HARDWARE

Solar Innovations^® offers superior quality in our hardware by utilizing stainless steel pins and extruded aluminum hinges to ensure the durability of our products. Solar Innovations^® patented recessed bumper handle provides smooth functionality and clean sitelines. Heavy saltwater finishes are available for coastal applications.

RIDGE VENTS

Thermally enhanced aluminum ridge vents provide natural ventilation to promote plant growth in glazed structures. Ridge vents work in tandem with eave vents, creating a circulation pattern by bringing cooler air into the structure through the eave vents while the warmer air escapes through the ridge vents. This circulation will make the structure more comfortable and help reduce the spread of diseases in plants. Vents can be set to automatically open when a specified temperature is reached or close when rain or snow is detected.

Features

GUTTERS AND DOWNSPOUTS

Gutters and downspouts are a functional necessity to any structure yet they need not be an eyesore; they can be aesthetically appealing and double as an architectural element. Gutters are available in several styles and finishes, including traditional copper, and include downspouts in standard, round, or fluted round shapes. We specialize in restoration projects and can provide custom cast aluminum elbows, drop outs, and extruded downspouts to mimic an existing structure’s architecture.

GRIDS

Decorative grids enhance the look of any structure, and are available in five standard types: low profile, ogee, colonial, traditional, and large-traditional. They can be formed into almost any grid style, including radius designs. Grids can be applied three ways: as interior muntins, exterior grids and Simulated Divided Lites (SDLs). Interior muntins are placed inside the airspace between two panes of glass and are typically more cost effective and easier to clean than exterior grids and SDLs. Exterior grids are placed on the interior and exterior of the window and work well with single pane glass but have drawbacks on insulated glass, as you can easily tell it is not a true divided lite because, at an angle, you can see the lack of structure between the glass panes. The solution to this is an SDL which provides an encapsulated bar within the glass, giving a better illusion of a true divided lite.

RIDGE CRESTING

Ridge cresting is used to enhance the ridge line of a glass structure, especially in Classic English designs. Several styles of ridge cresting are available. A finial and king post is typically used to terminate the ridge cresting’s length.

RING AND COLLAR TIES

The ring and collar tie serves as a structural brace and cross tie for larger structures or free standing structures. Decorative appliqués can be added to each side of the ring for additional interest.

Appliqué

APPLIQUES

Decorative appliqués are elements that can add character to structures. Each cast aluminum appliqué features one of two main motifs: the rosette or the Fleur de lis.

DECORATIVE CORNERS

Decorative corners, or eave spandrels, can be found in buildings as early as ancient Rome. An eave spandrel was historically the space between an arch and a wall or column, but can also occupy the space between a wall and a squared-off opening. While eave spandrels are primarily decorative, they can also be used for shelf supports or plant hangers.

SCREENS

Screen swing doors are available for both terrace and French doors. The screen swing door is constructed from an aluminum frame that mimics the sitelines of our glazed swing doors. Screens are also often incorporated into our eave and ridge vents.

MAINTENANCE AND SERVICE

Maintenance

A greenhouse, like any other structure, will require regular maintenance. The frame and glass will accumulate dirt, which will need to be removed, preventing future maintenance issues. Solar Innovations^® does not recommend using harsh chemicals, a simple solution of water, vinegar and dish detergent will work well to clean the frame and glass. Operable window and vent tracks need to be cleaned and checked regularly to maintain proper function. Always test your greenhouse accessories as a new season approaches. Motorized operations, such as ridge vents, will need occasional lubrication. Leaves and debris will also need to be removed from gutters.

Repair & Replacement Services

Our products are backed by an industry-leading warranty. In the event of a problem, our team has the technical skill and experience to evaluate your situation and determine the most effective options for repair, service, or replacement of your product. All drawings and information are saved for each project, so a preliminary site visit isn’t always required.

BENCHES/POTTING BENCHES

Benches are not only an essential component to any greenhouse but also can be designed to meet the needs of a wide variety of growers. Solar Innovations^® can build benches that best match the demands of each individual greenhouse. Here are just a few examples:

Master Gardener Potting Bench

Potting benches are used as workstations to pot flowers, store tools, and prune plants. A sink can be incorporated to enhance its functionality.

Fixed

Fixed benches are a staple in greenhouses. They have aluminum bases and are available with mahogany, galvanized steel mesh, or black polyethylene crosshatched tops.

Seedling

Seedling benches are raised beds on legs which allow you to grow plants directly in the soil. The bench has a solid bottom and can be designed to accommodate varying soil depths.

Rolling

Rolling benches have fixed legs and a movable top, allowing for the workspace to shift from aisle to aisle, freeing up valuable space in the greenhouse.

Tiered

Tiered benches can stand up to three levels tall and can be placed above the bench to expand space or under the bench for low-light plants.

Gravel

Gravel benches consist of a solid bench top, which is filled with gravel and water. This is an ideal bench for humidity-loving plants such as tropicals and orchids.

COLD GROWING FRAMES

Cold Frames are one of the oldest forms of greenhouses. They are essentially a glass box with aluminum framing and a lid. Their main function is to extend the growing season into early spring and late fall. They are placed directly above where plants will be grown. During the night and cold days, the lid is kept closed to retain heat. Then, when the days are warm, the lid is opened to allow for fresh air.

Cold Frames are historically constructed out of wood, which is subject to rotting after a few years and will require frequent maintenance. Solar Innovations^®’s Cold Frames are constructed out of aluminum, which will not rot, warp, or rust. Each unit is custom designed to your specifications; you may choose as many bays as needed and are available in all of our standard colors. They can also be modified to be heated from greenhouse ventilation if desired.

ENVIRONMENTAL CONTROL SYSTEMS

A fully functioning greenhouse often has many systems. They include watering, lighting, heating, ventilation, and various others. Plants will flourish if humidity, temperature, and air circulation are precisely controlled. Solar Innovations^® recommends an environmental control system that can automate each accessory’s operation, easing the burden of maintenance.
For the environmental control system to function automatically, data is collected from sensors positioned inside the greenhouse and from a weather station attached outside. The system monitors the data and controls the operation of accessories from predetermined settings. The ridge vents and windows will automatically open when the greenhouse becomes too hot. The evaporative cooler will start to operate if a desirable temperature is not reached. The same is true for heating and watering systems. Accessories can be grouped together or operated independently. For example, two ridge vents can be programmed to open simultaneously or independently. A staged opening allows ventilation units to open at varying degrees between the fully open and fully closed positions.

Advanced Technology

Software can be installed on your computer to control the greenhouse’s settings. Daily records can be created and saved for future reference. The software is capable of setting off alarms if the temperature falls out of range, and can even send an alert to your cell phone.

EVAPORATIVE COOLERS

A greenhouse has the potential to get too hot in the summer, even with ventilation. In order to preserve the plants, cooling needs to be incorporated. Solar Innovations^® recommends an Evaporative Cooler which reduces temperature and adds humidity to the greenhouse.

The Evaporative Cooler draws air over a wet pad, by way of a fan. As the water passes over the pads, it evaporates and takes heat with it. The air then passes into the greenhouse and can be up to 30° cooler. Evaporative Coolers consume ¼ less energy than traditional air conditioners. Evaporative Coolers exchange air; rather than re-circulating stagnant air; a benefit for greenhouses which need fresh air to combat pests and disease.

Portable Evaporative Coolers

Portable evaporative coolers provide a low-cost, environmentally-friendly means of keeping spaces cool. Water and forced air are combined to reduce air temperatures by as much as 26°F. These coolers have a computer-programmed control panel with LCD display, and come with a convenient remote control.

FANS

Circulation Fans

Circulation Fans eliminates stagnant air, which breeds diseases, while also reducing the spread of fungi and pests. Moist leaves combined with warm temperatures will promote disease growth. They help dry plants quicker and reduce pests. A Circulation Fan can also help eliminate pockets of hot and cold air in a greenhouse. Two fans are typically used in a greenhouse and placed in opposite corners.

Features

• Fully enclosed motors
• Hanging mount
• Framework built for greenhouses & high moisture environments
• Optional variable speed controllers
• White frame

Circulation Fan Models

Exhaust Fans

Exhaust fans pull hot air out of a structure and prevent it from becoming trapped at the ridge. They help circulate air within a structure and maintain a constant temperature.

Features

• Triggered by temperature
• Best suited for monolithic glazed greenhouses
• PVC shell with aluminum blades
• Motorized operation
• Lower intakes pull cool air into the greenhouse
• Placed opposite exhaust fan
• Shutter must be 6″ larger than the fan

Available Models

FERTILIZER INJECTORS

Fertilizer injectors are the most efficient way to feed plants by delivering liquid nutrients directly into the water supply line. They are a fast and accurate way to feed an entire garden, landscape, nursery or greenhouse.

LIGHTING

The amount of hours a plant grows can be extended with supplemental lighting known as grow lights. Most year-round greenhouses will require lighting during the winter so plants receive the necessary photoperiod for normal development. Grow lights can be used to produce artificial sunlight on shady days when plants do not receive sufficient sunlight. Plants can produce more flowers or fruit in a shorter amount of time with this additional lighting.

High-Efficiency LED Light

Durable and energy efficient, an LED grow light provides uniform lighting and is designed to improve yield. These grow lamps are fully programmable and use 40 percent less energy than High Pressure Sodium lights. They are also easy to install and you never need to replace bulbs.

High-Pressure Sodium Light

A high-pressure sodium light emits more light in the red/orange wavelengths to promote greater flowers and fruit. It is recommended for production of vegetables and cut flowers. Using this light constantly, even during daylight, can provide increased production.

Metal Halide Light

A metal halide grow light emits more light in the blue wavelength spectrum to promote vegetative plant growth. Plants grown under this type of light are typically taller and bushier.

Workspace Lighting

Most lights are not designed to withstand the amount of water and humidity in greenhouses. Lights will eventually rust, break, or stop functioning. Water-resistant systems with fluorescent lights can be mounted at the ridge of a structure for illumination.

HEAT MATS

Heat mats help gardeners have better success rates with seedlings and cuttings. They warm root areas approximately 10–20° F over ambient temperature to improve germination process. Perfect for one standard 10 in x 20 in propagation tray, allowing for even warming of the entire tray.

HEATERS

The interior temperature of a greenhouse is critical to how well your plants grow. All glass structures are prone to solar heat gain, meaning the sun’s rays generate heat, which is trapped inside the glass structure — think of getting in your car after it has been sitting in a sunny parking space all day. But during the winter, the sun can’t do all the work; most greenhouses will need to be heated to provide the proper indoor environment for plants. Some tropical plants require the greenhouse be kept at a constant, warm temperature, while hardy cold crops such as lettuce and kale thrive at lower temperatures.

Heating Systems

Several sources can be used to produce heat, including: electric, propane, natural gas, oil, radiant, wood, and solar thermal. These heating systems have different advantages. Several factors, including greenhouse size, location, use and glass-type, determine what size heater, or number of heaters are required.
Our greenhouse experts evaluate your needs to provide the best heating solution, including the proper fuel source.

Solar Innovations^® offers four styles of heaters, including floor mounted and roof-hung units, where vents are placed in the walls, electric roof-hung units that are vent-less, and a wall mounted, direct vent version. All heaters run efficiently through thermostatic temperature controls and a matchless ignition.

Hydronic Heating

Hydronic heat is a clean, healthy, and energy efficient method of heating a glass structure. The motor of a hydronic heater does not blow air through vents where dust resides, resulting in a cleaner system. These motors are also quieter than those found in traditional heating systems. An added benefit of a hydronic heater is it is energy efficient, reducing utility bills.

Interior Mount Gas Heater

Interior Mount Electric Heater

Exterior Mount Heating Unit

For large greenhouses Solar Innovations^® recommends an exterior mount heater with a louvered vent mounted opposite the heater.

HOSE REELS

A retractable hose reel makes a greenhouse a less cluttered and safer environment. An adjustable return control system eliminates the dangerous whipping action found in other brands. This reel has several mounting configurations.

HUMIDIFIERS/FOGGERS

Humidifiers, or foggers, are utilized to control moisture levels in the air for optimal plant growth. When humidity drops below a predetermined level, a sensor triggers the humidifier to activate, blowing a fine mist throughout the space. For more advanced applications, high pressure foggers and oscillators are available.

PLANT HANGERS

A variety of plants can be grown year-round in hanging baskets within the greenhouse. Solar Innovations^® offers a variety of hangers.

SHADES AND BLINDS

The summer sun may be too intense for some plants, causing them to burn or die. One way to avoid this situation is to install a shading system. Solar Innovations^® provides operable, fixed, interior, and exterior shading systems. Most of our shades and blinds are designed for high-moisture areas and are water, bacteria, and fungi resistant. Fixed shades permanently attach to the frame and are appropriate for greenhouses that are used to grow delicate plants such as orchids or other tropical flowers that may be sensitive to overexposure. Operable shades allow you to control the amount of light entering the greenhouse and are available in manual or motorized options.

SHELVES

Shelving is a great way to expand your greenhouse’s growing area. The units can be placed directly in front of a window, on a solid wall, or located high on the eaves and come in a variety of styles.

Open Grate

Open grate shelves allow for optimal air flow and ease of maintenance and are available in galvanized steel or polyethylene plastic tops.

Wood

Wood shelving inserts are made of hardwood species, like mahogany and cedar. These slats can be stained or left in their natural state.

Adjustable Metal Bracket

Metal bracket shelving supports are an economical choice, have a functional appearance, and can be mounted above or below the shelf.

Decorative Casting Bracket

Decorative corner shelf supports work well with conservatory-style greenhouses and can double as a plant hanger.

SINKS

Your greenhouse will be much more functional with the addition of a sink which can stand alone or be incorporated into one of our benches.
