Greenhouses for sale can be a great investment for a backyard gardener or small business owner. For years, backyard greenhouse gardening used to be primarily the preserve of large commercial plant manufacturers who needed a controlled, enclosed environment to grow food and flowers indoors, off-season. More recently, however, because of new building techniques and more modern materials, many kinds of greenhouses are now available that offer a great deal more square footage and can often be moved from one area of your garden to another almost easily.
Whether you need a few small-sized greenhouses for a few plants or a large multi-tiered greenhouse suitable for dozens of plants, there are many affordable models on the market today. These newer Greenhouses for sale come with many of the same features as the more expensive models, but are generally less expensive and take less time to build.
One of the first things you will want to consider when you are looking for greenhouses for sale is the size of the greenhouse you need. If you are just growing a few seedlings here and there, then a compact greenhouse will be just fine for you.
However, if you want to start growing plants for personal enjoyment and/or selling them, you may want to look into purchasing a much larger model. You will also need to determine whether you will use your greenhouse year-round, or only during certain months of the year.
If you will be using your greenhouse gardening to start seedlings to harvest, then you will likely be growing smaller starter plants and vegetables in the greenhouse. A 10-gallon bucket should be sufficient for these plants, although the size of the bucket does not necessarily have to match the size of the greenhouse.
If you want to use your greenhouse for growing larger plants and vegetables, then you will need to have a more substantial greenhouse with multiple trays and multiple levels. Greenhouses for sale that do not contain enough square footage for growing starter plants can make the greenhouse difficult to use for the purpose that you purchased it for.
Some people prefer to use their greenhouse to grow plants that do well with a more even, indirect light source. These types of plants include African Violets, Stachys, Aster, Sunflowers, Sedum, and Photinia. You should be aware that these plants tend to do best in a greenhouse that is located approximately four to six feet away from the plant.
This means that you should either have a greenhouse with diffused lighting, a large window, or a fan placed in a downward position to bring the diffused light into the area. These plants also do better when the soil is moist; therefore, adding water to the soil before seeding will help your plants grow healthier.
When shopping for the right greenhouse coverings, you should always go with the best selection available to you. It is important to choose a cover that allows airflow, yet protects against cold and extreme temperatures. Your chosen greenhouse coverings should also be able to handle windy conditions, high humidity, and extremely high temperatures. If you are unsure which coverings would best suit your needs, you should consider a greenhouse gardening catalog to get an idea of what styles and materials are available.
