A tailor-made greenhouse is probably something every gardener or vegetable farmer dreams he had. The genius concept of artificially creating an optimal environment for plant growth is something that has been known to be around since the Roman era. Of course, we may think of greenhouse construction as simply throwing up a frame and stretching some see-through plastic sheeting over it, but there’s more to it than just that.
There are various styles and types of greenhouses, but the general idea is to erect a system of framework that will support glass or plastic sheeting. This glass or plastic can either be completely transparent or it can be translucent. But it shouldn’t be opaque as this would defeat its cornerstone purpose of admitting into the greenhouse, the sun’s radiation.
Although the sun’s rays initially enter the greenhouse via radiation, the primary mode of heating inside greenhouses is convection. Radiation enters the greenhouse through the transparent roofing and walls, and is absorbed into the various plant-life and soil, translating into heat. This heat is then released into the greenhouse atmosphere via convection, thereby raising the temperature.
Building the greenhouse is the easy part – comparatively speaking. In order for greenhouses to be the most effective, the temperature, humidity, UV lighting, irrigation, pest and disease-control must all be optimized. Nowadays this is often done by computer software to ensure accuracy. But essentially, all you need is a basic knowledge of what environment the particular plant you’re trying to grow needs, and provide it to the best of your ability.
A thermometer, hygrometer, and vents are some things you won’t be able to do without. Although monitoring the temperature and humidity of your greenhouse is something you can do with simple tools, boosting or reducing the temperature by large amounts is something you’ll need additional equipment for. Also, providing a proper irrigation is essential unless you want to be watering it manually yourself everyday – or TWICE a day in fact. greenhouse air conditioner
Although my article covers the more technical aspects of greenhouses, it leaves out the practical building steps. For exact details on how to build a greenhouse for your unique needs, I suggest you purchase this greenhouse guide. It will take you through the exact steps needed to complete your greenhouse project and ensure you don’t cut any essential corners. If you’re serious about having a greenhouse on your property, this is a MUST!
Greenhouse Myth #1
Greenhouses are only used by “rich” or 1st world countries because they’re greedy and want to have strawberries all year-round.
– Hmm, although the “greedy” and “wanting to have strawberries all year-round” may be true to some extent, this is not the ONLY reason greenhouses exist! Many high-latitude or inarable countries and regions depend greatly on greenhouse production for their very survival!
