As more consumers become concerned about safety of the produce they buy at the supermarket, the popularity of growing your own veggies and fruit is increasing. When you raise your own food you control what sorts of chemicals your plants are exposed to and you can easily “go organic”.

Most growers find it reasonable and convenient to install a greenhouse to extend the growing season and maybe even opt for year-round growing. Many gardeners find that the quickest, easiest way to get a greenhouse is to purchase a greenhouse kit that comes complete and ready to assemble.

Especially for those who are not skilled builders, building a greenhouse from scratch can be an intimidating idea. This is one of the greatest advantages of buying a greenhouse kit; you don’t have to be a skilled builder. All you have to do is follow simple directions and put your greenhouse together.

No matter what design you have in mind for your greenhouse, you will be able to find a greenhouse kit to match your ideal. You can find greenhouse kits at retailers but the best prices are most likely going to be found online. Examples speak louder than rhetoric so let’s take a look at some greenhouses!

1. Halls Popular 86 Greenhouse: A traditional, free-standing style greenhouse with a large 8’ x 6’ growing area. It features a single sliding door, aluminum frame gutters, one roof vent and  powder coating with double 4mm carbonate walls all for the online price of $1,399 (less fall purchase rebate=$1,199)
2. EasyStart Lean-to Greenhouse: If you have little space, a lean-to greenhouse is what you need; the EasyStart is designed to even fit apartment balconies.

There are no limits to the designs of greenhouses available online; glass, polycarbonate, domes, “pup-up” plastics and the list goes on. If you are in a hurry and on a budget, a greenhouse kit is the best option for you.

When I was growing up, my family always had a huge garden. It was only my parents, my brother and me in the family but every year mom would go completely overboard with her planting and we had a garden big enough to feed a small army. My dad was very creative and he decided to build my mom a greenhouse so she could get a head start on the growing season every year. He built this greenhouse from recycled windows.

Where to Find Recycled Windows

When my dad built mom’s greenhouse he got the windows from friends that were tearing down an old house on their acreage to make way for a new home. Today, that remains one of the best ways to obtain recycled windows; to find a building that is being torn down. Many times you can offer to take the windows out yourself and the owners or demolition company will let you have them for free if you do the work. Sometimes they even throw in other materials you need such as doors or salvageable lumber.

Other great sources of recycled windows are yard and estate sales. Shortlist and visit a few garage sales at elite address. Here you may find windows that are not only functional but pretty as well such as clear leaded glass panes. If you are not in a great rush, you can make quite an adventure out of assembling all the recycled windows you need to build your greenhouse.

Probably the most reliable sources of recycled windows are salvage yards. Salvage yards are wonderful places for anyone interested in recycled building materials such as concrete block, glass, doors, lumber, beams, stepping stones, fence material and hardware; essentially anything that can be salvaged from a building or landscaped area. Salvage yards offer great prices; just pennies on the dollar compared to new prices.

Assembling the Recycled Windows

One of the interesting challenges to using greenhouse recycled windows is that you will most likely end up having all shapes and sizes of windows to contend with. It is like putting a jigsaw puzzle together to align and plan the walls and roof from dissimilar sizes of material. When you think you have enough windows to build your greenhouse, lay out the recycled windows and try to put together groups that make sections the size you need.

When you are ready to start you will need to adjoin the windows to a support to create a wall. Most recycled window greenhouse builders prefer to use 4×4 (or larger) treated corner posts and 2×4’s for the framing structure. The advantage to the wood frame is that you can nail wood window frames to it and screw or bolt metal window frames. Most of the stress of building this style of greenhouse is in the lay out. Once you have it figured out which window goes best where, you have it licked.

One thing to be aware of with recycled windows is that older windows are probably single paned and will not have much insulation value.

Greenhouse recycled windows add character to the structure and often bring back memories of the greenhouses of long ago.

If you love to garden outdoors chances are you will love gardening indoors. Home garden greenhouses are one of the best investments a gardener can make to jump start their outdoor garden or to enable them to grow plants year round indoors.  As a rule, if you can grow it outdoors or in flower beds you can grow it in a home garden greenhouse.

Though similar, outdoor and indoor gardening are different in a couple ways. The temperature in a greenhouse is controllable whereas an outdoor garden is at the mercy of the elements. Since a greenhouse is fully enclosed no rain enters to water the plants so some sort of water system or plan must be devised to ensure greenhouse plants receive the proper amount of water to flourish.

Here are some of the home garden greenhouse advantages:

• In cold climates a greenhouse makes it possible to grow produce and flowers year round. With a greenhouse you can enjoy fresh home-grown salad even in the dead of winter. When there is snow on the ground, nothing is better for the soul than to go to the greenhouse, take a seat and enjoy the beautiful blossoms surrounding you.
• A greenhouse is ideal for wintering over cold weather sensitive outdoor plants. You can save money by taking plants from the outdoors and putting them inside a greenhouse to protect them from the cold so you can replant them in the spring.  Further, your greenhouse offers a secure haven for propagating cuttings from parent plants during the winter for spring transplant.
• Seeds may be planted early in the season to start them for transplant as seedlings into the outdoor garden or flower beds. Especially if you live in an area with a short growing season, this is a very advantageous feature of greenhouse gardening. You can plant seeds while snow is on the ground and the seedlings will be ready to plant outdoors by the times the ground temperatures have warmed sufficiently for successful transplant.
• Gardening is a great de-stress mechanism. It is a proven fact that gardening is relaxing.

Maximizing your Home Garden Greenhouse Advantages

To maximize the benefits derived from your greenhouse, locate it where it will receive the most sun. Exposure to the sun is the most important factor for making your greenhouse endeavor successful. A couple of things to consider in relation to sun exposure are trees and structures. When deciding where to locate the greenhouse, be aware that growing trees may some day be tall enough to cut off light and watch that existing buildings do not shade the greenhouse.

Monitor the temperatures in the greenhouse with a thermometer placed in a shady place in the greenhouse. Sun can generate heat levels high enough to dehydrate plants so it is critical to be aware of the conditions inside the greenhouse. If necessary, vent to alleviate excessive heat.

A garden greenhouse is not only relaxing but it can provide you a steady supply of fresh produce and flowers year-round. You can protect and propagate your plants, no need to be concerned with weather conditions outside since the greenhouse provides the optimal environment for cold weather sensitive plants.

Nowadays most everyone has come to the realization that global warming and greenhouse gas effect are not merely figments of some mad scientist’s imagination. We humans are fouling our own nest, so to speak. We have irresponsibly pillaged and plundered the resources of this planet until it has grown tired of us and our actions. Hopefully not too late, we can make a difference and lend a hand by recycling and supporting the use of sustainable resources.

For the devoted green gardener, a greenhouse built out of recycled materials is the perfect way to reflect one’s dedication to the cause of saving Planet Earth. What better way could there be than by growing plants to encourage cleaner air and using recycled materials so that no new resources need be harvested in order for you to build.

Where to Find Recycled Material in Which To Build Your Greenhouse

Everything you need to build your greenhouse is available as recycled materials. Don’t throw away plastics from your kitchen any more, use them to start seeds or as containers to hold seedlings. You know those plastic containers with a clear plastic lid that you get your rotisseries chicken in at the deli? They make great seed starters. Fill the bottom with potting soil, plant the seeds, water and snap on the clear lid for a perfect starter environment. Egg cartons too make a wonderful seed starters. Put one seed in each egg section full of potting soil, water, cover with plastic and set in a warm, sunny spot. Before long, you will have little plants popping up.

A few interesting statistics about recycled products available for use in your greenhouse:
Hanging baskets made of 44% recycled material, rose containers of 94% recycled material, greenhouse containers of 74% recycled materials and plug carriers also of 94% recycled materials. Your greenhouse gardening environmental footprint need not be very obvious when you use all recycled materials inside your greenhouse.

Options for Building your Greenhouse from Recycled Materials

If you wish to build a greenhouse from recycled materials you have a couple of options.

1. To build your greenhouse from salvaged material

2. To build your greenhouse from products you purchase that are either part or wholly made of recycled materials.

One of the most popular salvage building methods is to build the greenhouse using windows salvaged from sites where buildings are being torn down. Often the parties that are demolishing the existing building will let you have the windows for free if you tear them out or just for saving them from having to haul them off. Also at demolition sites you can generally find brick to salvage for the base of your structure or even for the floor if you intend to include flooring.

Most areas have salvage centers where you can buy doors, lumber, windows, beams and sometimes hardware necessary to build your greenhouse at extremely low bargain, salvage prices. Your local hardware stores will certainly offer recycled plastic sheeting and maybe even PVC for your watering system.

Salvaged and recycled materials not only save you a lot of money, but you will also be saving Planet Earth when you build your greenhouse out of recycled materials.

If you live in an area with icy cold winter months, you will necessarily need a heater to control your greenhouse temperatures and keep your plants flourishing. There are many types of heaters available for greenhouse use such as electric, gas and paraffin heaters. Among greenhouse gardeners, convenient, an easy to use electric greenhouse heater are most popular.

Things to Consider when using an Electric Greenhouse Heater

There are a couple of issues that must be addressed in order to make electric heat feasible in any greenhouse. First, there must be power to the greenhouse whether a permanent source (hard wired) or a temporary fix like a breaker-type heavy duty power cord (not recommended as a permanent power solution). Second, water and electricity are not a good mix. Use care placing and wiring your greenhouse heater for safety reasons. Electric heaters designed specifically for greenhouse use are often more costly but well worth it to eliminate potential water-electric conflict.

Choosing an electric greenhouse heater with a fan is very advantageous. It not only warms the air but circulates it to avoid stale air fungus problems and cold spots in the greenhouse. Some greenhouse gardeners opt for a complete heat/AC system that not only warms air during cold periods but cools it in the summer. You have to admit that such a system would eliminate a lot of the summer greenhouse worries such as when to open the vents and when to put up the shade cloth. A year round totally controlled environment would be the ultimate for any greenhouse gardener.

Why Use an Electric Greenhouse Heater

Among the many advantages of electric greenhouse heaters over gas or paraffin heaters are such features as excellent thermostatic control, no fume by-products and you don’t have to transport any fuels like paraffin or have a tank filled as required with gas. Thanks to efficient thermostatic control, electric heaters have very quick response time when the temperature undergoes a sudden change. All that is required with an electric heater is to plug it in, program the thermostat and relax.

Electric greenhouse heaters come in many sizes and shapes. The size (capacity) of heater you need is dependant on the size of your greenhouse; the larger the greenhouse the more heater capacity will be needed. You can install the heater as a permanent fixture in your greenhouse or use a heater that is portable.

Tip: Avoid blowing air directly on plants as is may be damaging. Bench your plants and blow the heat (or cool air) at floor level to avoid plant damage.

Recommendations: When choosing an electric greenhouse heater, go for a 2,000-3,000 watt heater with a thermostat. With a thermostat there is no reason to use lower powered models that would run continually; more that 3,000 watts increases the chances of damaging plants with water loss and overheating. For a few dollars more you can purchase a heater with variable fan speeds and an option for blowing non-heated air. For the extra dollars this is a very desirable, useful feature and one you should opt for.

Pros of an Aluminum Greenhouse

There are many distinct advantages of opting for an aluminum greenhouse rather than a simple cold frame or wood greenhouse.

Minimum Maintenance: For one thing, aluminum has a very long lifespan and it requires very little maintenance. In addition, the fact that metal frame aluminum greenhouses are suitable for extending growing seasons anywhere makes it a very popular choice for greenhouse buyers. Probably the one thing that greenhouse owners like the most about aluminum is that it does not rust or rot and will therefore not need to be repaired or replaced periodically.

Weather Resilient: Aluminum greenhouses are known for their weather resilience. Aluminum framing is extremely strong yet amazingly slight and as a result, sun exposure is not interfered with by the greenhouse frame. Plants get the optimal exposure to the sun in an aluminum greenhouse.

Easy to Assemble: An aluminum greenhouse is simple to assemble, merely bolt it together to make the most durable greenhouse available. An extra added attraction of aluminum is that it is available in a variety of colors such as white, green, silver, bronze and dark silver or charcoal.

More Compatible: Another attractive feature of aluminum greenhouses is the frame’s compatibility with a variety of types of paneling. Glass, plastic and polycarbonate window panels all can be used with aluminum framing. Aluminum framing allows you to simply slide in whatever sort of panels you wish to use.

Lightweight & Portable: Of all the metals we have available for building a greenhouse, aluminum is the most lightweight and the most portable. Of the types of greenhouse frames on the market today, aluminum frames are the most popular likely do to their cost and their durability when compared to other materials.

Cons of an Aluminum Greenhouse

There are a few disadvantages to using aluminum to build your greenhouse.

More Expensive: Aluminum is costlier than wood or other metals such as steel. Not only that, to build your structure as strong as if you has used steel would require significantly more aluminum frame supports be incorporated into the greenhouse design. In other words, to build an extremely strong greenhouse with aluminum does take more material than it would if you opted for steel or wood.

Soft Metal: Aluminum is a fairly “soft” metal with some flex characteristics. Due to this feature, aluminum can bend under stress and may not stand up well to harsh winds or heavy snows.

No Insulation Value: One serious disadvantage of building an aluminum greenhouse is that aluminum does not have any insulation value.  Aluminum allows heat to transfer straight outdoors from your heated greenhouse in the winter; you will lose a lot of heat through an aluminum frame in other words. In addition to heat loss, aluminum allows condensate to form on the inside of the greenhouse frame. Aluminum is not heat efficient by any stretch of the imagination.

If you are researching greenhouses you will find that there is more information online than most of us could process in a lifetime relating to buying or building greenhouses. Even though a little overwhelming, the vast amount of information available assures that after looking into the various options you will choose the greenhouse that is right for your distinct needs and conditions.

Have you priced the cost of small greenhouse kits lately? Most of us are on a tight budget with the poor economy so rather than spending more than you need to on a greenhouse kit, why not build design and build your own small greenhouse?  You may find that when you design and build your own greenhouse you can to afford to build a little larger greenhouse than you originally anticipated.

Looking for Step by Step Greenhouse Building Plans?

If you aren’t currently confident in your building abilities check out the courses as the local community college or the seminars offered at retailers such as The Home Depot and Lowe’s. Many times “do-it-yourself” instructional courses are free so everyone can learn how to be their own handyman.

Building a small greenhouse is not a daunting task unless you decide to install an automatic water system, power supply and automatic ventilation system; the more complex the greenhouse the more skills and money required to build it. If you are not skilled enough to do install these types of systems one idea for building a greenhouse with all these features is to save money on materials by purchasing everything you can from a salvage yard. Then you could perhaps afford to have a professional complete the water, power and ventilation systems.

Building your Small Greenhouse

1. Design and sketch the plan for your greenhouse including all appropriate dimensions and features.
2. Level the intended site for your greenhouse; the more time you spend making the site absolutely level the less time you will spend trying to make things fit together later.
3. Lay a foundation. A small greenhouse does not require an elaborate foundation; a railroad ties or other large timbers are ideal.
4. Place a geo-textile layer on the ground you have cleared and leveled as a weed barrier.
5. Build a wood-frame base atop the foundation using 4 x 6’s adhering to your greenhouse design. Use a level to assure that the frame is perfectly horizontal.
6. To create a water permeable floor for the greenhouse, fill the frame’s inside with gravel.

Sourcing Cheap Materials for your Small Greenhouse

You now have a level foundation and base; now you are ready to build a small greenhouse. The cheapest materials are those bought at very minimal prices from a salvage yard. At salvage yards you can find windows, doors, louvers, vents, posts, lumber and most likely materials to build a watering system such as PVC.

Accumulate all the materials you need according to your plan and then get out the tools, nails, bolts, screws and any other hardware necessary to complete the structure. Materials that you cannot find at a salvage yard will be readily available at a local hardware store. The greenest materials available at the local stores are those made from recycled sources. Environmentally you cannot beat salvaged and recycled materials for your greenhouse.

Once you have everything you need, use all your skills to follow your design and put your small greenhouse together.

These days we are all looking to save a penny or two wherever we can. Many consumers are looking at adding a greenhouse for growing their own produce and to lower the grocery bill. One of the nice features of having a greenhouse to grow your own produce is that as the grower you can choose whether to grow organically or whether to use chemicals and pesticides. If you are like most of us today who are watching expenditures, you need a way to build a greenhouse cheap.

How To Build A Greenhouse – What do I recommend?

Determine the Size & Shape of your Greenhouse

The first step in building a greenhouse is to decide how large it will be. Sketch a plan and make sure that your planned greenhouse will fit where you intend to put it. Once you have settled on the size and shape, do some comparison shopping to decide how you are going to build your greenhouse for the least amount of money.

Is a Greenhouse Built with Salvaged Materials cheaper than a Greenhouse Kit?

There are a couple of methods to look at for building a greenhouse cheap. If you have little time to spend accumulating materials and building a greenhouse, you should start by looking at greenhouse kits. Greenhouse kits come in a very wide array of sizes, shapes and prices. Go online and look for the greenhouse kit that has all the features you want; make sure it is the right size and shape for the space you have allotted. Note the prices you find and if a price is affordable for you, order it delivered to your door. Sometimes it is cheapest in the long run to just buy at a good price when you haven’t the time to build from scratch.

However, if you have plenty of time to shop around for materials and build your greenhouse, the cheapest way to build a greenhouse is with salvaged materials. Once you have decided the size and shape of the greenhouse make a comprehensive list of all the materials needed to complete the greenhouse.

With your list in hand, head for the nearest salvage yard where you will find all sorts of salvage and scrap materials at a fraction of the original cost. Search the salvage yard for the materials on your list such as aluminum framing, glass windows, doors (you might even get lucky and find a door still hung in its frame!) and lumber.

Salvage yards commonly have various types of concrete blocks that work splendidly for foundation purposes. Salvaged water piping is cheaper than buying the new stuff at the local hardware store if you intend to put a water system in your greenhouse. Use your imagination and substitute cheap salvage materials for every greenhouse part you can. Use glass windows instead of sheet plastic for the body of the structure and plastic and PVC can work for reinforcements if you can’t find the right wood or aluminum.

When you are trying to figure out how to build a greenhouse cheap, your local scrap and salvage yard is your best bet for good materials at extremely reduced prices.

You finally have the greenhouse you have always wanted. However, you do not really have a clear idea of exactly what greenhouse supplies you are going to need. To some extent the supplies for greenhouse gardening are dependent on your intent for your greenhouse; do you intend to raise vegetables only, or flowers or even small trees? Will the greenhouse be used year round or only for starting plants for later transplant into a garden spot?

Supplies for greenhouse gardening are easy to find online commonly at prices less than local nurseries or supply stores offer. There is a huge amount of information online explaining greenhouse gardening and helping you select which type is right for you.

Winter & Summer Greenhouse Supplies

If you intend to winter plants over, you will need a heat system for the cold winter months. You can choose from electric or gas heaters, whichever is most suitable for your project.

For the summertime you will need to purchase shade cloth to protect the plants in the greenhouse from the intense heat of the sun through the glass (or plastic) of the greenhouse roof and walls. You need to preplan a water system or count on dragging a hose in and watering by hand or by sprinkler.

Once you have the winter heat source, summer shade and water addressed, you can concentrate on what supplies you need to get your plants growing.

Basic Supplies

The easiest, most logical place to start is at the floor level. The simplest way to keep weeds from intruding inside your greenhouse is to lay durable polypropylene flooring. This flooring material not only prevents weeds from coming up but allows water to drain. It is easy to install, you simply unroll it and stake it down.

Potting Benches: Once the flooring is complete, you can start moving in the benches where your plants will be placed. Various types of benches are available; bookshelf style benches, simple benches and stands. Benches and stands come in many materials including aluminum, wood and molded polymer. Most greenhouse gardeners prefer to have a potting bench inside the greenhouse for the sake of convenience. A potting bench provides a workspace for potting and transplanting your plants.

Planting Trays: You will need planting trays for starting your seeds. Planting beds can be purchased, made or salvaged; some innovative gardeners like to use egg cartons to start their seeds. Once the seedlings are large enough to transplant, you will need prepared growing beds. Growing beds are best built by hand to fit your greenhouse perfectly according to your design. They need to be deep enough to accommodate the deepest root system of the various plants you intend to grow. They should be filled with potting soil and fertilized when you plant your seedlings.

Thermometers: You need at least a couple of thermometers to hang inside the greenhouse so you can monitor the temperature. Hand tools you need include a trowel, hand rake, shovel, scissors, clippers, small rake and small hoe. Be sure to stock up on hand gloves to save your hands from cuts, scrapes and other injuries.

Seeds: Last but certainly not of least importance of the supplies for greenhouse gardening, are the seeds. Don’t forget the seeds!

These are the basic greenhouse supplies that any successful gardener will be sure to have on hand.

We all enjoy fresh vegetables year round but most of us have to go to the produce department of the local supermarket to obtain them. Then, unless they are marketed as organic produce, we have no idea what the produce has been exposed to such as pesticides and chemical fertilizers. One of the best ways to assure the safety of the produce you consume is to grow it yourself.

Think Ahead When Considering Greenhouses Plants

Before you start your greenhouse plants you need to make a growing plan. Are you going to be simply starting the greenhouses plants for future outdoor placement or are you going to be growing the produce entirely within the confines of your greenhouse? Your growth plan and the size of your greenhouse have a direct effect on the produce you will be able to grow.

Once you have your greenhouse assembled and everything ready to go, you need to decide what you want to grow in your greenhouse.  If you are using your greenhouse to start plants for later transplant, the sky is the limit as to what types of produce, flowers and herbs you can plants. In areas with short growing seasons greenhouse plants normally include those sorts of produce that take a longer time to mature than the growing seasons allows. In other words, in an area that allows for an 80 day growing season, it is recommended to start corn and other veggies that have over 80 day maturity periods. Corn, pumpkin and winter squash are all slow to mature so are great choices for starting in a greenhouse.

If you intend to use your greenhouse to produce a year-round food supply you will need to carefully plan for cooling in the summer and heating in the winter in order to maintain the greenhouses plants at proper growing temperatures.  For year round fruit and veggie production some of the easiest and best plants are tomatoes, peppers, eggplant, lettuce, cucumbers, carrots, radishes, spinach and beans. You can realistically expect to have salad and greens as well as many vegetables available year round when growing greenhouse plants.

Root crop plants such as turnips, beets, carrots, onions and garlic are perfect for deep dirt boxes placed under growing benches. For pole beans, peas, cucumbers and tomatoes, use tub containers. Leafy low growing vegetables like lettuce and radishes should be planted along side tall vegetables in the tub containers.  For the best crop of corn you have ever grown, plant your corn seed in a prepared bed on the floor of the greenhouse. A good way to save space is to plant pumpkin and squash among the corn.

Be sure to include plenty of herbs in the ranks of your greenhouses plants; they are natural insecticides. One suggestion for making your own organic insecticide spray is to add garlic and onions to a jar filled with water and let stand for 7 days. Spraying your plants with onion/garlic water protects them from insects.

Your greenhouse will not only be a food source for your family but it will be a great source of enjoyment for all who enter its walls.
