    THE GREENHOUSE COVERING

    What is Solexx Covering?
    The plastic Solexx greenhouse covering is made of high-density polyethylene extruded with the structure of corrugated cardboard but with the enduring qualities of plastic. The covering is insulated and can withstand virtually any weather condition.

    Can I buy the Solexx greenhouse covering separately?
    Yes. Purchase Solexx panels in 4' x 8' and 4' x 12' sheets (the actual the size is slightly larger) or you can buy continuous rolls of the twin-wall paneling. You can use them to build a custom greenhouse or to cover an existing frame. The frame supports should be spaced approximately 2' apart. In addition to the Solexx covering, we sell H-channel to join the panels, U-trim to seal the open flutes, and galvanized screws to attach the covering to your structure. The panels come flat but can be rolled in a cardboard drum for UPS shipping.

    How do I install the covering?
    Screw directly through the paneling and into the frame using 1" wood screws or 3/4" drill screws when going into a metal frame.  Screws should be about 6" apart around the perimeter and 18" apart in the center - generally about 32 screws for each 4' x 8' panel. Heat and cold will cause some contraction and expansion, so you will want to install the covering on a mild day.

    What is the best direction to apply Solexx panels and rolls?
    Solexx glazing has a UV additive throughout the material, so all sides of the material are protected from the sun. They can be applied with either side exposed. Attach the glazing either horizontally or vertically, but you get the strongest support when the flutes run perpendicular to the frame. We recommend the framing or trusses be no more than two feet apart to best support the panels.

    What do I do where the panels come together?
    There are two options, H-Channel or overlapping.  H-Channel is used to join the long side of the panel together and should run perpendicular to the greenhouse studs. It is meant to float between the panels to allow for expansion and contraction, so no screws go through the H-Channel.  The H-Channel is held in place by attaching screws 2 1/2" above and below it.  A second option is to overlap the panels.  Solexx panels are designed with an extra 1 1/2" so you can overlap the panels by shingling them.

    How do I cut Solexx glazing?
    The material can be easily cut to size using a utility knife or a sharp kitchen knife.

    How far will the panels curve? What do I do at the peak of my greenhouse?
    The panels are very flexible and curve easily around tight radiuses. In fact, the material can be folded over peaks and around corners for a water-tight seal.

    The greenhouse covering is not clear. Isn't it too dark inside to promote growth?
    No, actually the greenhouse covering transmits 70-75 percent of the available light. Most plants only need 40 percent light to grow, but 70-75 percent available light is the optimal growing range. Even on cloudy or rainy days there is usually enough light for growth. The panels diffuse the light evenly throughout the greenhouse eliminating "hot spots" and shadows.

    Does the covering break down in the sun?
    Solexx has a UV additive throughout the material the extrusion process. Solexx is covered by a 8-year limited warranty against ultraviolet breakdown. Farm Wholesale greenhouses have been in the field for over fifteen years and there has been minimal UV breakdown. All plastics do eventually break down when exposed to direct sunlight for extended periods of time, however, the panels are easy and inexpensive to replace. In high sunlight areas, the life of the panels can be extended by using a shade cloth and/ or placing the greenhouse in a partially shaded area.

    Will the greenhouse covering discolor?
    No. The covering will not yellow, mold or mildew. The material will not scratch so you will not have the "cloudy" appearance as with other types of greenhouse paneling.

    How do I clean the paneling?
    Solexx can be rinsed or wiped clean without worry of scratching. The glazing is impervious to chemicals, so you can safely wash it with a mild detergent.

    How does the greenhouse covering hold up in snow and cold weather?
    Solexx greenhouses are undamaged after being covered in several feet of snow and exposed to subzero temperatures for most of the winter. Snow tends to slide right off the slick paneling material. Many greenhouse materials yellow from the sun or cold but Solexx is resistant to yellowing.

    How can I heat my greenhouse?
    The greenhouses can be heated with propane or electric heaters with thermostatic controls. In mild conditions 5 gallon, covered black buckets filled with water will trap the solar energy during the day and release heat for most of the night. Another option is adding rabbits to your greenhouse. Rabbits put out 8 BTU’s per hour which amounts to roughly 2.5 gal of fuel in 6 months. Rabbit manure also adds heat and makes a great non-burning fertilizer. For more complete information, there is a book available called Solviva by Anna Edey.

    Is it expensive to grow all winter?
    The cost of heating your greenhouse will depend on your area and what you plan to grow. Many plants require only a 45-degree nighttime temperature. The 3.5mm Solexx covering provides more insulation than most other hobby greenhouse materials. Customers have reported being able to heat their greenhouse all winter for under $20.00 a month in the coldest months. Heating costs can be reduced by using buckets or plastic jugs of water or by lining the greenhouse with a layer of Visquine or bubble wrap in the cold months. To find out what size heater is right for your greenhouse, use our heater calculator.

    What can I grow in my greenhouse?
    There are numerous vegetables, herbs, flowers, tropical, exotics and cacti that flourish in a greenhouse environment. The book The Greenhouse Gardener's Companion is an excellent resource.

    What type of glazing would be best in my area?
    Solexx glazing is available in 3.5mm (Solexx XP) and 5mm (Solexx PRO) thicknesses. The 3.5mm panels are recommended in most areas as they provide more light transmission. The 5mm panels are used in very cold climates (for added insulation) and at high altitudes. The 5mm paneling is also recommended on many custom structures for extra support.

    What do I do where the panels come together?
    There are two options, H-Channel or overlapping.  H-Channel is used to join the long side of the panel together and should run perpendicular to the greenhouse studs. It is meant to float between the panels to allow for expansion and contraction, so no screws go through the H-Channel.  The H-Channel is held in place by attaching screws 2 1/2" above and below it.  A second option is to overlap the panels.  Solexx panels are designed with an extra 1 1/2" so you can overlap the panels by shingling them.

    THE GREENHOUSE KITS

    Who developed the greenhouses?
    The greenhouse kits were developed by Mike and Bev Perry. Mike and Bev hold degrees in Plant Science and Biology. They developed the greenhouses after working with the corrugated plastic in several applications. Both Mike and Bev witnessed accelerated growth with a product designed for tomatoes and decided to make a greenhouse for their personal use.

    How Are The Greenhouses Shipped?
    Most greenhouses are shipped UPS. The 8' Garden Oasis comes in five boxes, two 8' x 7.25" x 5" boxes, one cardboard drum approximately 2' in diameter and 4' long, one 24" x 12" x 12" box, and a small box for the Louver. You can easily fit the greenhouse in the back of a truck or roomy sports utility vehicle.

    Where are the Greenhouses Sold?
    The greenhouse kits are now sold in all 50 states and Canada. All kits are available through our mail-order catalog and our web site. We also have a retail outlet in Salem, Oregon.

    What Makes Farm Wholesale Greenhouses Different From The Others On The Market?
    One of the most unique features of our greenhouse is the Solexx covering. The Solexx greenhouse provides highly diffused light (the best type of light) to your plants so they will have optimal growth.  University testing has shown that plants grow best under diffused light.  We also can deliver the greenhouse to our customer's door by UPS. Another feature that makes us different is our built-in bench frames. With almost all other greenhouse kits, benches are a large additional expense.

    The greenhouses come in a kit? What does that mean?
    The greenhouse is sold unassembled. This helps us to keep shipping costs and greenhouse costs low. Each kit comes with complete written instructions and computer generated drawings. The pipes are pre-cut and color coded (in most kits) for convenience and you can call our toll-free customer service line if you need help.

    How long will it take to assemble the greenhouse?
    The 8' units can usually be assembled in a weekend or two.

    Can I assemble the greenhouse by myself?
    A team effort is best when assembling the greenhouse kit. Using simple household tools, smaller greenhouses can usually be assembled within a weekend. Precise framing alignment is easy with custom steel fittings. The flexible greenhouse covering goes on easily. Galvanized, self-tapping screws with neoprene washers provide secure panel attachment. Slip the U-Trim into place and you're ready to enjoy your greenhouse.

    How do I prepare my greenhouse site?
    You can place your greenhouse on your lawn, over bare ground, on a gravel base, over a wood deck, on a concrete slab, or a brick patio.  Very little site preparation is required for your Farm Wholesale Greenhouse. Simply find an area in your yard that gets plenty of sunlight (southern exposure is best) and level the ground.  Lay down flooring over the surface to prevent weeds in your greenhouse while allowing necessary drainage.  Pour about 3" of compacted 3/4" crushed rock on top for added drainage and a sturdier floor.  And of course, don't forget to tie down your greenhouse once it's in place!

    What will I need to start growing?
    The most important accessory is a tie down kit. The greenhouses are lightweight and must be tied down. We have a tie down kit available, but you can use any method that will securely anchor the frame. Some methods include, tying the frame to cement anchors, screwing brackets over the frame and into a deck. Heaters, fans, and grow lights are also available. Base vents are inexpensive and easy to install. See the book The Greenhouse Gardener's Companion to determine your specific requirements.

    What tools will I need to assemble my greenhouse?
    Screwdriver, variable speed drill, sharp knife or utility knife, tape measure, step ladder, GE Silicon-2 caulk, Caulking gun, clear PVC glue, level.

    Will The Greenhouse Handle High Winds?
    As long as the greenhouse is firmly anchored you should not have problems with wind. The combination of a strong frame and flexible paneling works very well in adverse conditions. Many of our customers live on the coast and frequently experience winds of 70 mph. One customer in New Jersey has a greenhouse that survived Hurricane "Bob" with no damage from the impacting tree branches.

    Will the greenhouses withstand heavy snow loads?
    The greenhouses do well in snow. The paneling is slippery so snow frequently just slides off the structure, and low temperatures will not harm the plastic. If there is a snow build-up the greenhouse can support several hundred pounds of pressure.

    Is the greenhouse portable and/ or can it be disassembled?
    The greenhouse is portable; it is easy to put onto a trailer for transport or move from one area of your yard to another for the best light. It is not suggested that the greenhouse be disassembled - the panels are attached to the frame with screws and once the screws are removed, realigning the panels to the frame would be very difficult and there is some gluing involved in construction.

    What if I don't want benches in my greenhouse?
    Solexx Greenhouses are designed so the benches are part of the frame structure and are essential for the strength of the greenhouse. The Early Bloomer Greenhouse is a great alternative for those who need the floor space and prefer not to have benches.

    THE GREENHOUSE MODELS:

    What models are available?
    Farm Wholesale has five greenhouse models to chose from: Solexx Garden Oasis, Solexx Harvester, Solexx Conservatory, Solexx Garden Master, and the Early Bloomer Greenhouse. There are also two Cold Frame models to chose from.
