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.

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.

Here is what to do now…

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.

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.

Today the increasing concerns about chemicals used on our food products is leading more people to construct a lean to greenhouse to grow as much of their food year-round as they can. When most of us think of a greenhouse we think of large plastic covered commercial growing structures or of the neighbor’s glass windowed beauty in their backyard. However, one of the most popular greenhouse options is the lean to greenhouse… or half greenhouse… that attaches to the home or other building.

What is a Lean to Greenhouse?

A lean to greenhouse literally leans up against an existing wall. In days past, the only type of greenhouse people built were lean to greenhouses… most frequently attached to garden walls. Heat from the wall would help to warm the greenhouse through the night. During the day, the wall protected the greenhouse from over heating. Today, we are turning to lean to greenhouses when we have little space for a regular greenhouse.

The common lean to greenhouse is comprised of a roof, a front wall and two end walls. One of the real advantages to a lean to style of greenhouse is that the necessary utilities such as electricity and water are close and easy to access. If you choose, you could place your lean to greenhouse so that you could enter directly from the house. Most lean to greenhouse owners select the style that takes the least amount of space from the yard yet allows the most inside growing room.

The most difficult part of installing lean to greenhouses is the height of attachment to the existing structure. If you have a 2-story home you won’t have any problems. But, with ranch style houses, attachment height can become problematic. Remember to allow enough roof pitch to slough snow and deter leaking; the recommended roof pitch is 2.5 on 12 pitch which in layman’s terms simply means for every 12” of roof slanting from the house there needs to be at least a 2.5” drop.

Building Your Own Lean To Greenhouse

You could build your own lean to, but there are many ready-to-install lean to greenhouse kits available for $250 and up. Lean to kits make it very simple… they come complete with all the pieces and parts you need and they take no time at all to assemble. Although you may still find it cheaper to source all the parts yourself and and use a good set of greenhouse plans.

One important issue that will need to be addressed is the base- what sort of base do you intend to place the lean to greenhouse on? Some owners decide to let the greenhouse sit on the ground but it is advisable to put your greenhouse on a base to hold it in a stable, proper position. If you buy a kit, most likely the base will be included. If you need a base, you will find many to choose from online at very reasonable prices.

Many owners put their lean to on a patio or deck. If your decking or patio surface has any gaps in it, you should place either plywood or some other material that will prevent air from flowing in through the bottom.

A lean to greenhouse is the perfect solution for those who have little space but a desire to grow their own organic produce.

As autumn approaches it means that cooler temperatures are on their way and frost won’t be far behind. For those who have greenhouses that they keep plants in year round, autumn means it is time to start thinking about the greenhouse heaters. If your greenhouse is not heated and needs to be, what kind of heat source should you look for? What about gas greenhouse heaters; what are the pros and cons of that type of heat for a greenhouse?

For most of us the choice of heaters is either electric or gas. When we compare them side by side we see that electric heat is more expensive than gas heat and it is only a convenient source when the greenhouse is at or near a power source. If there is no power source nearby it is very inconvenient to run extension power cords over long distances. On the positive side, electric heat does not produce fumes and it does enable efficient heat distribution.

If you opt for gas heaters, you will have no need for either electrical wiring or a strung out extension cord. You can use gas heaters that are portable and therefore useful during the “off” season. Propane gas costs approximately 50% the cost per BTU as electricity, therefore gas heaters are much less expensive to operate than electrical heaters. On the negative side we find that gas heaters are not quite as efficient as electric heaters and they do produce fumes. Interestingly though, space heaters fueled by propane produce far fewer greenhouse gas emissions and air pollutants the space heaters fueled by either electricity or fuel oil.

Chances are if you are a greenhouse gardener you are concerned about the environment. Even if your concern only extends to worry over what sort of chemicals you are ingesting when you buy store-bought produce (enough worry to greenhouse garden) that means you are one of the increasing number of Planet Earth dwellers that have taken action to improve our environment. So, when it comes time to consider what sort of heat to use in your greenhouse, you are likely to look for the greenest alternative.

When comparing electricity and gas above you quickly see how the issue can be a bit cloudy; each type of heat has its advantages and each its disadvantages. But, from an environmental point of view, there really is no comparison. Gas greenhouse heaters are the cleanest option available.

Another advantage of propane is that the placement of propane tanks is not regulated by the EPA, you can place a tank as near to your greenhouse as you want; even underground placement is acceptable. Propane is not damaging to water or soil; it is not toxic and poses no danger to the environment. It is for these reasons that the EPA does not regulate the placing of propane tanks.

Propane is listed as an approved, alternative clean fuel in the 1990 Clean Air Act. It is also approved in the National Energy Policy Act of 1992. For those who prefer to preserve and protect our planet, propane is the ideal choice.

I think most of us would agree that there is nothing better than a tomato picked ripe, straight from the vine. A vine ripened, juicy red tomato in the middle of winter may sound a little like a dream but with a greenhouse and a little research you can enjoy fresh tomatoes year round.

Whether it is for the pure enjoyment of growing your own tomatoes or out of concern for the types of toxins most store bought produce has been exposed to, a greenhouse offers you the chance to nurture and harvest your own home-grown tomatoes. Tomatoes can be a little quirky and finicky to grow so a little research will help you avoid the most common pitfalls of growing tomatoes in a greenhouse.

Get the Right Seeds when Growing Tomatoes in a Greenhouse

It is important to get off to the right start with your greenhouse tomatoes. You don’t want to use just any seed such as the ones you saved from last year’s outdoor garden. There are certain strains of tomato seeds that have been especially developed for use in greenhouses; look in any seed catalog or online for these special seeds to help you avoid some of the common problems encountered with greenhouse tomatoes.

Is your Environment Right for Growing Tomatoes in a Greenhouse?

Start your tomato seeds under heat mats or in constant warm conditions. Let them grow for a couple of weeks and then transplant them into large containers (at least 10 gal size) to ensure plenty of room to grow. Note: Before you re-use a container, rinse and sanitize with bleach to stop the threat of any disease that may be present in the container from previous use. Also, always use fresh soil to prevent disease from passing from previous plantings.  Be sure to add bone meal to the new container soil following package directions. Bone meal is a good source of calcium which protects the tomato plants from Blossom End-Rot, a deficiency caused by a lack of calcium that causes the tomatoes to turn black at the blossom end.

Before you place the tomato plant in the greenhouse, be sure the greenhouse environment is disease and pest free. If you notice problems, treat them before placing your tomatoes in the greenhouse. To further protect the tomato plants, plants herbs like lavender and basil at the same time to deter pests such as white fly and other bugs. Place the tomatoes in a space where they will receive plenty of sunshine and also will be bear the heat source during the cold months.

Lighting is Important too!

Artificial lighting will likely be necessary to keep the tomatoes growing during the winter. Without adequate hours of light each day, tomatoes will not grow. Sodium lights are the best type to use since they encourage blooms and setting. For optimal results, use supplemental lighting 16-18 hours a day; be sure to use the correct watt light for the electric set up.

Keep the greenhouse temperature between 60°F and 90°F otherwise the plants will refuse to produce fruit.

Now your tomatoes are planted, all you need to do is water them and provide them a little TLC. Before long you will be enjoying tomatoes you grew in your greenhouse.
