Optional Accessories

Solexx circulation fanCirculation Fan (8") - The horizontal air flow fan [1/100 HP, 0.6 amp, 115 volt, 1550 rpm, 448 CFM] is recommended to help circulate the air within your greenhouse to prevent it from becoming stale. It is often paired with a heater to help ensure even diffusion of heat throughout the greenhouse. One fan is typically sufficient even for large greenhouses though some customers prefer to have two. The fans have a maintenance-free motor with pre-lubricated ball-bearings that is thermally protected. The patented guard spacing and custom engineered 5-wing aluminum fan blades gives lower noise levels and an adjustable mount is included for versatile installation. The fan has a variable speed capacity and the cord comes in the box unattached for a hard-wire install. Larger fans are also available upon request.

Solexx closeable base vents Closeable Base Vents - These ABS polymer vents allow fresh air to continually flow through your greenhouse. The vents are mounted near the base in each corner of greenhouse for natural ‘ground-up’ cross ventilation. Each vent measures 4quot; high x 9" wide and can be closed during cold weather to preserve heat.

Solexx wire bench shelvesComplete Wire Bench Shelves - This Solexx greenhouse includes the shelf frames but not the actual shelves. These heavy-duty, metal wire shelf racks fit directly into the frames and allow for drainage and continuous air circulation around your plants. The shelves are powder-coated white and this kit includes eight 29" deep x 47" shelf racks. Mounting ties are included for simple installation. Some customers choose to save money by building their own shelves out of wood or some other material.

Solexx easy-flow louver ventExtra Louver Vent - Extra easy-flow louver vents are available to provide even more ventilation for your greenhouse. They are made of rugged, outdoor-grade Solexx paneling and are specially designed for this greenhouse.

Solexx solar powered louver vent openerSolar Powered Louver Vent Opener - The solar powered louver vent opener automatically opens and closes in response to heat to help keep your greenhouse ventilated on warm days. It does not require batteries or electricity as it has a piston coated with a mineral wax that expands and contracts in response to temperature changes. The automatic opener allows you to be away from the greenhouse without fear of overheating. Customers must decide between manual and solar powered openers at the time of purchase as the manual vents can not be upgraded later.

Solexx tie down kitTie Down Kit - The tie down kit is designed for easy assembly and it will keep your greenhouse secure in high winds and inclement weather. The 15" anchor rods are buried into the ground next to the greenhouse and the J-hooks are attached to the greenhouse frame. Turnbuckles are used to tightly connect the frame to the anchors. The anchors are easy to disconnect as well in case the greenhouse is ever moved. Anchors are used approximately every 8 feet and 30" long anchors are available for larger greenhouses or for sandy soil conditions.

Schaefer 16 inch exhaust fan with thermostat (HV-51)Solexx exhaust fan thermostatVentilation System - Solexx offers a powered ventilation system to provide superior air circulation inside the greenhouse while helping to keep the temperature down on especially hot days. For this greenhouse, the recommended ventilation system from Schaefer Ventilation includes a 16" exhaust fan (1250 CFM, 1/10 HP thermally-protected motor, 1725 RPM) (HV-51), a 16" motorized intake shutter vent (115V, 1/2 amp gear motor) (HV-61), and a thermostat with wiring. Circulation fans (8" or 12") are a recommended accessory as well for use with the ventilation system.

The exhaust fan has a aluminum blades and rugged commercial-grade PVC shutters. The exhaust fan requires a rough opening of 16 5/8" x 16 5/8". Exhaust fans are typically installed high on the front end wall above the door so that there is cross ventilation with the vent or vents on the opposite end.

The built-in shutter with rigid blades automatically opens and closes when the fan is powered on or off. The safety guard has a powder coat finish over a zince coating for extra longevity. The thermostat (30°F-110°F temperature range) is weatherproof and corrosion-proof with all polycarbonate thermoplastic construction and a stainless steel capillary sensor. It is not affected by surges, lightning strikes, or power outages like a digital thermostat. The ventilation system carries a two year limited warranty from the manufacturer and is also made in America.
