Advice of installing greenhouse

So You're Thinking About Buying a Greenhouse


Eventually every gardener considers the purchase of a greenhouse. A greenhouse offers the opportunity to enjoy gardening every month of the year. It also represents a considerable commitment in money, time, and space. This guide has been developed to help you select from the variety of available greenhouses.


You will want your greenhouse to meet both your gardening needs and your pocketbook. This guide can help you decide what type of greenhouse best fits these requirements, whether it is one from us or a different greenhouse.


1. What size greenhouse?
Greenhouse size is usually dictated by factors like available space and construction costs versus need or desire. When choosing a size, consider if the greenhouse will be used year-round, seasonally, or mainly as a sunspace. If you want a greenhouse to house an extensive collection of houseplants, then it is best to plan on building or purchasing a structure that is larger than your current space requirements. Most hobby greenhouse owners find they need a larger greenhouse than they originally thought. Upgrading later on may be more costly than ordering a larger unit from the beginning. Another important size consideration often neglected is height. You want to make sure your greenhouse has adequate head room. You need to consider both peak and eave (sidewall) height. Taller houses are also easier to heat and ventilate because the air has a greater buffer area.


2. What will the greenhouse be used for?

I want to get a head start in early spring and/or a few extra growing weeks in late fall.
This is an easy task for a greenhouse. How much extra time the greenhouse will provide will vary based on your local climate and if you choose to equip the greenhouse with automatic ventilation and heating. Any of the greenhouses we offer can be used for season extension since heating and cooling requirements are very low for this purpose.

I am interested in overwintering plants that are not hardy in my area.
Overwintering, maintaining the minimum temperature needed for plants to survive, requires heating the greenhouse even if it is for a short period of time. Greenhouses suitable for overwintering can also be used for season extending. Inexpensive greenhouses like the FlowerHouse and Little Greenhouse are fine in milder climates that you don't expect needing to heat the greenhouse more than about 30° F above the outside temperature for any extended length of time.

If you are in a colder climate with temperatures that sometimes drop to 0° F or below, a greenhouse with an insulated covering is recommended. These greenhouses are not only retain heat better, but they also generally offer a tighter seal than other greenhouses making them easier to heat. The Cross Country, Grow More,Aspen, and Sunshine models would be better suited for this purpose.

I want to grow plants in a greenhouse during the winter.
This is different from overwintering plants because plants generally need higher temperatures to grow and thrive versus just staying alive. In this case, an insulated greenhouse will be worth the extra investment because of the lower heating cost. The Cross Country, Grow More, Aspen, and Sunshine models are better greenhouses for growing in the winter.

I want a greenhouse to grow plants year round.
A tightly sealed and insulated greenhouse with high light transmission is desirable for year-round vegetables and flowers (especially in northern climates). Remember, greenhouses are designed to store heat from the sun and create a warmer environment inside of them, so use in the summer in most areas would be limited at best. A greenhouse with an evaporative cooling system is recommended to keep temperatures at a minimum when it is hot outdoors.

3. How elaborate do you want the greenhouse to be?
If you are just starting seedlings or wintering over a few plants and are looking for the least expensive option to do so, you should consider the FlowerHouseand Little Greenhouse. If you want your greenhouse to be a focal point as well as functional, the Sunshine and Cross Country greenhouses are among our most attractive structures. The Cape Cod and Cottage series of the Cross Country are available with a combination of glass and polycarbonate providing both beauty and function.


4. Is a building permit required?
Check local ordinances for required setbacks from property lines, design requirements, and other requirements. Call your local building department. Some hobby greenhouses may not need a permit, but it is a good idea to check anyway.



Selecting a Site for Your Greenhouse


Choosing the right site for your greenhouse will not only determine how well it works as a greenhouse, but how much you will enjoy it. There are several factors to consider in choosing your site.




1. Sunlight
If the greenhouse is going to be used primarily for starting seeds and transplants or plant propagation in the summer, place it in partial shade to minimize heat buildup. You can use a shade cloth to control the amount of sunlight reaching the interior if a partially shaded site is not available. If the greenhouse will be used for growing in late fall and winter, or growing plants to maturity, it will need maximum exposure to the sun. It should receive a minimum of 6 hours of direct sunlight everyday. It is best to position the greenhouse with the ends facing east and west. This will provide more heat gain from the sun during the winter and create less shadowing in the greenhouse. If the southern exposure is restricted, but open to the east, southeast, southwest, or west, turn the greenhouse to the winter sun. Remember the difference in sun angles from summer to winter (the sun is much lower in the winter).





Sometimes a shade tree can be an advantage, providing some shade for the greenhouse during the hot summer and letting the sun in after losing its leaves in the fall. The problem with overhanging trees is one of falling branches that can damage your greenhouse.


2. Accessibility
You want your greenhouse to be easily used. A good site should be sheltered from high winds and easily accessible from your home and garden. Remember the need to move soil, plants, fertilizer, and yourself to and from the greenhouse. Access to utilities such as electricity and water are important requirements to remember also when selecting your site.


3. Weather
Many regions have chronic weather problems such as heavy rain, snow, and/or strong winds. Heavy rains may cause drainage problems in and around the greenhouse. To avoid standing water, choose a spot on high well-drained ground or install a drainage system before the greenhouse is erected. Snow is usually not a problem as long as you provide adequate insulation and heating. Strong winds can be a real problem. In cold weather, winds blowing over a greenhouse can drain it of its interior heat escalating energy costs. Windbreaks are your most effective weapon. A windbreak is an obstacle that "breaks" up the force of the wind. Trees, shrubs, fences, and other structures can all be effective windbreaks. Remember that a windbreak can also obstruct light. Try to locate one where it will block the least amount of light.

4. Ease of construction and maintenance
A level, well drained site will obviously be easier to work with and maintain than a low, swampy, or sloped area. It is also a good idea to locate your greenhouse away from children's play areas.



What's the Best Material for Greenhouses?


There really is no best material for a greenhouse. It is hard to know what's best when there are so many different materials used to make greenhouses. Aluminum, galvanized steel, wood, PVC, glass, fiberglass, polycarbonate, polyethylene, etc. They all have their place in greenhouse construction. Your needs and budget will determine which is best for you.

How to identify the quality of poly carbonate solar panels good enough?

How to choose solar panels? How to identify solar panels is good enough?

Selection of inexpensive but high-quality PC sun panels, sun panels for users is critical, you may not necessarily be appropriate, cheaper is not necessarily the best.

Let me explain the reason:

1, high-quality import pc panel means high price. Because they are made of imported raw materials to produce new poly carbonate, thermoplastic machine for solar panels and technical requirements are very high.

2, We all know that UV coated sun panels solar panels can increase service life. But the   prices are expensive. here is the thing we need to considering about the UV: thicker and using time. Since UV coating materials are expensive (several hundred thousand dollars per ton), low-grade film solar panels although India "coated with UV", in fact there is no anti-ultraviolet UV coating.

3, Surface anti-droplet plastic sheet make things easier in greenhouse applying. Plus a PC sunshine board anti Dettol process is generally used in greenhouses, coz modern greenhouse, especially the high degree of difficulty of soilless culture, the use of solar panels anti Dettol process enables PC sunshine board surface layer of fog film, not direct formation of water droplets, dropping damage cultivated flowers or plants.

4, the complex structure of solar panels price good quality. Take a simple rice-shaped solar panels, we can do rice fonts PC sun panels of 40mm, these PC sunshine plate by a plurality of stable triangular structures can enhance the structural strength of solar panels, effectively resist typhoons natural disaster. Say that the U-shaped lock plate (standing seam U plate), these PC sun board with 100% leak-proof dust-proof design, because of its excellent design has a strong stability, can reduce the input support system, Some places do not even need support.

Pls abandon the inferior PC plastic sheet

1, the number of impurities or air bubbles was caused by a variety of reasons: A low-end machinery and equipment backwardness B processing technical imperfections inside how much is one of the main raw material of recycled materials C (eg more or larger bubbles and particles, Description is poor raw materials, recycled materials and solar panels luminance bad yellow or blue.

Sunshine board as a new plastic materials, has many functions, the majority of customers are also likely to have a first contact, they may not understand what the pc sheet is? 

they called hollow sun board board either, and now the market there are many quality PC sun panels, to meet different customer needs, but on the plate, because of different quality, a lot of manufacturers and merchants are shoddy, so many grades of basic sun panels on your eyes, we probably consumer market according to the PC sunshine board is divided into 5-year, 10-year warranty, but many manufacturers in order to achieve lower prices, the quality just become poor, and you can see in China domestic market. They also sold as 10 years.

How to extend polycarbonate sheet using time and cleaning?

Poly-carbonate sheet was used into greenhouse, high building and many apply.
And how can we clean and protection it?


   In accordance with the right approach and appropriate thing regular cleaning can extend the life of PC boards. 

  1, Small area cleaning

   2, using warm water to wash it

   3, Flushed with a mild soap or household detergents against the warm water, and with a soft fabric or sponge to remove dust and dirt. Water should be compatible with addenda PC sheet. 

Cleaning Note:

   Do not polish or cleaning PC sheet with a strong base, do not use a dry cloth or a stiff brush to wipe a hard look and prevent scuffing appearances.

   Ban with butty cello-solve and isopropyl alcohol solution to clean the UV  PC sheet. Advocate cleaning solvent

   Ethanol, petroleum ether (BP65), ethane, Kang dioxane. Langming PC sheet to prevent contact with incompatible chemicals.

   PC sheet cutting:
  PC sheet can be cut using a sharp wallpaper: PC sheet available handsaw be cut, referral should cut the sheet secured to prevent violent oscillations lead sheet tear.

The features of polycarbonate panel on production process

What's the feature of pc solid sheet on produce process?

Polycarbonate(PC) plastic sheet in manufacturing production is particularly need to pay attention, because the PC panel may be affected by many factors, such as temperature, time, pressure and production speed, etc., which will affect the PC plastic.

Before molding, PC resin must be thoroughly dried. The fluidized bed drying method can be drying, vacuum drying, hot air circulation drying. In fact, PC plastic and other plastic products of the process is a lot worse, but there are also some differences, so today, as you talk about PC features it has a kind of plastic.

1, It belong amorphous plastics, in different stages, the control temperature is different.

2, PC plastic thermal stability is relatively good, and the relative molecular mass of the increase can be improved.

3, PC plastic creep resistance, good dimensional stability, but it is not easy to eliminate internal stress.

4, under high temperature water easily degradable plastic PC required moisture content below 0.02% during molding.

5, if not pay attention, then it is easy to crack phenomenon appeared.

6, in the production process, and its apparent viscosity greatly influenced by temperature, less affected by shear rate, with the relative average molecular weight increases.

In addition, PC dont  have melting point, but high melt viscosity. PC has a benzene ring in the molecular chain, lead to greater rigidity.

Polycarbonate factory price analyzed in China

So many people will have this question about polycarbonate hollow/solid/frosted/embossed sheets,

Why is the sun panels with 10 mm thickness prices are different from diff factory?  Here is Yanley answering.

In fact, the price of solar panels and weight level there is a certain relationship. After falling weight has not declined since the sun thickness, a direct consequence of the vertical wall and reduce the thickness of the studs, so that solar panels drop impact resistance, sunshine board price is lower than the regular factory prices. 

For example: the wall thickness of the conventional double-layer hollow sun board 8 mm standard 400μm, under normal circumstances can impact standard is 10 kg iron ball does not break free fall two meters. Standard 8 mm and 10 mm double-double sheet, you can fight general hail impact. However, if the upper surface of the plate 8 mm double did not meet the above specifications, the thickness is generally lower weight 8 mm solar panels is about 300μm, resulting in the case of hail breakdown.

If you fall under the weight of the wall thickness of sunshine board up to standard, and that the thickness of the studs will certainly reduce the price of solar panels will naturally be reduced.

Glass glue is available when PC sheet glass leaking?

Glass glue is available when PC sheet  leaking?

       Many PC sheet (somewhere called plastic sheet) installation is not so good, faced with the situation leaking late, for this case, we recommend a neutral glass, plastic can trap water place, but poly-carbonate sheet is not in contact with cement, since the cement composition will contain sun panels broken. Seriously affect the life of the solar panels.

Considerations in the use of glass, plastic we need to pay attention to:

1, glass glue the most common problems is black mold, even with waterproof glass, plastic, glass, plastic mold can not completely avoid such problems. So long there is water or flooding areas not construction.


2, plastic glass should know something about glass glue will know is an organic substance, soluble in oil, xylene, acetone and other organic solvent species, and therefore can not be glass, plastic construction with a substrate containing such substances.

3, ordinary glass adhesive must have the participation of the moisture in the air to cure, special and special-purpose glass, plastic (such as anaerobic) is excluded, so if you want to place the construction of extremely confined spaces and dry, then ordinary glass glue will not work.

4, neutral glass glue to stick to the surface of the polycarbonate hollow sheet required to clean, can not have other attachments (such as dust, etc.), otherwise the glass adhesive curing will appear bonding is not strong or shedding phenomenon.
