If you are a city or suburban gardener then weather extremes can be very frustrating for you.  Your gardening is shutdown in the winter.      

Your greenhouse, like the larger models should have a screen door and a screen vent that allows air to circulate and allows for cooling when it is hot.  You can also let outside air in to prepare plants that you have started in the winter to acclimate themselves for transplanting outdoors.  When the vents close you can increase the humidity if you want to help plants that need it.  Otherwise you can keep possibly damaging wind and rain out.

Most commercial kits make use of UV resistant material that resists rips and tears.  Velcro, snaps, or zippers are used for fasteners on the openings.  If you decide to go with plans you might do the same or actually use a hung door.  Either way, your portable greenhouse will keep you gardening year round.

You can use polycarbonate or polyethylene plastic for any or all of the greenhouse covering.  Some people use it for both the walls and roof while others use aluminum sheets for the roof.  Usually kits will use an aluminum frame while construction using plans would use a wooden frame.

Grow Year Round With A Portable Greenhouse

The benefits of a portable greenhouse couldn’t be easier to see.  You will be able to grow year round, protecting your plants in the winter, being able to grow your own seedlings.  In summer you can provide a stable environment for the plants, and in fall you can continue even though the days have begun to grow shorter and the nights get colder.

Portable greenhouses are inexpensive compared to a permanent structure.  Portable greenhouses can also be fitted into the smallest backyards.  And you know, there are even portable greenhouses as big as 50 by 100 feet.  They are portable because they can be assembled quickly by 2 people and easily moved with partial dis-assembly.  These larger portable greenhouses are mostly used commercially whereas the 8×10′ and smaller are usually bought by backyard greenhouse enthusiasts. 

Types of Portable Greenhouse

As with full sized permanent greenhouses there are various styles available.  Lean-to which can be attached to a house or garage to save on construction costs and ease of providing electricity and water.

Miniature portable greenhouses which are collapsible.  These are various sizes and can be used for perennials and other small plants.  They can also be used to start plants in the spring.

You can gain a lot of satisfaction if you  build your own greenhouse.  Many different designs and plans are available and you will also gain the freedom to grow in any season or climate and to grow in comfort while you work.

If you build your own greenhouse you can save a lot of money.  Good greenhouse plans and attention to detail can bring you a great place to nurture your plants. Here are some things to consider to build a great place and maximize your budget.

>> Greenhouse Design And Plans

1.  Consider using salvage materials.  Usually this means more work because you have to clean the materials and you need to adapt your plans to what is available.  Greenhouse plans – storm windows, it’s been done before, you just need to find the source and plan it out.  What is the cheapest way to build a greenhouse from scraps? Careful planning -in any construction project planning is everything.  You may alter your plans many times but planning is all important.

2.  Determine the climate of the place where you live. An insulated greenhouse is appropriate for cold climate areas. For warm places, a greenhouse with shade control is needed.  But you will probably find in most areas that you need both.

3.  A greenhouse should be designed with proper air circulation spaces, ventilation, pest control soil, heaters for winter season, and humidity control devices.  Sometimes in winter you just need to increas the thermal mass with many milk jugs or drums full of water.  The water is heated by day and has enough mass to hold the temperature up at night.

4.  When you select the location of the greenhouse, care should be given that sunlight hits it.  When you build your own greenhouse you will probably want to orient the longest side to the south to allow maximum sunlight in the winter.  Be aware too that in summer months it is sometimes nessecary to use a shade cloth to help keep the heat down.

5. Home greenhouses today are often covered with a poly material.  Some have found surplus tempered glass from salvaged storm doors.  Depending on the size of the greenhouse it may be difficult to find enough.  The materials chosen also affect the type of frame you need.

6.  The greenhouse floor and foundation can be as simple as building the structure on dirt, perhaps railroad ties as a base.  If this is done the greenhouse must be anchored to the ground to keep it from blowing over or even getting picked up in a storm.  A dirt floor also means you can plant crops right on the floor.  A concrete slab is also a good choice.  Consider your budget and choose accordingly.

7.  Many accessories can be added to a greenhouse.  The good thing is this can be done over time which will keep your cash outlay down at the beginning.  Automatic watering systems, heating systems, ventilatiion are all things to consider.

8.  Learn what the “good bugs” are.  The inscets that are beneficail to your garden.  Insects like the Praying Mantis and many kinds of spiders can be a welcome addition to your greenhouse and will help you avoid needing insecticides.

9.  Be sure to plan for storage of your supplies and the things to help you maximize your greenhouse experience.

How long will it take to build a greenhouse, can you build a greenhouse in one day?  You might build a small greenhouse in a day but chances are you will spend at least several weekends.  A major problem in greenhouse construction is that most people fail to do enough planning and talking to others who have built greenhouses.  They often underestimate the time and expense of building.  Good  green house plans can help you avoid this because you will find reliable bills of materials and time estimates.

You can build your own greenhouse and with a little extra effort save a bundle.  A greenhouse will help you in all aspects of your gardening.  You can prepare plants for an outside garden while it is still cold and so they will be of a good size when the planting season begins.  Your family will benefit too from the variety of fresh foods you can provide all through the year.
