Dwarf walls offer better rodent protection for your greenhouse. The glass will also be easier to keep clean, as it is located above the rain splash. Pots and tools won't break the glass at floor level, so a dwarf wall greenhouse can last longer. It's also easier to trim or mow the grass near the edge of the greenhouse if there's a dwarf wall. The cons are that dwarf wall miniature greenhouses are more costly, and the greenhouse will not be easy to re-site if you want to move it.

Having a greenhouse means never having to quit crop and flower growing because of the weather. The sky's the limit when it comes to deciding on a style for your greenhouse. Lightweight and weatherproof aluminum is the preferred material for greenhouses. There are quite a few concerns when selecting a building site, no matter which type of greenhouse you choose.

No one buys a greenhouse spontaneously. If you are anything like most devoted kitchen gardeners you will rapidly find yourself using your new greenhouse to raise young plants in spring, even growing salads over winter, and possibly providing a short-term home for a tender plant which needs shelter for winter, even if your original intention was just to grow tomatoes and cucumbers.

Greenhouses have traditionally been made from glass, which makes the most of light transmission and decreases maintenance compared to plastic coverings. Fiberglass reinforced polyester, polycarbonate, acrylic, and polyvinyl chloride panels are all rigid clear plastics used in greenhouse construction. Plastic coverings must be changed every 2-3 years to retain high levels of light transmission although the functional life and strength of the film can be extended by the addition of 1-5% vinyl acetate.

You can build your own greenhouse from scratch, or you can use any one of the dozens of commercially available greenhouse kits. Depending upon the type of glazing provided, prices of greenhouse kits vary widely. The most costly component in many greenhouses is the glazing material. Whatever glazing material you purchase should be made specially to resist the sun over many years without losing clarity.

Careful planning is important before a home greenhouse project can be started. The greenhouse should be positioned where it gets most sunshine. Maple, oak, and other deciduous trees can effectively shade the greenhouse from the strong late afternoon summer sun; however, they should not shade it in the morning.

Good drainage is another must for the site. Greenhouse floors need to have excellent drainage. Floors can be made of concrete, stone slabs, brick, sand or even dirt. A greenhouse needs to maintain a minimum temperature of 55'F for most plants, so proper heating and cooling systems during the winter and summer months are also very important.
