Greenhouse Construction And Materials

Posted on by

There are many different styles and ways to build a greenhouse for your backyard. Your decisions on how to construct, heat, cool, and maintain an overall working environment will mainly depend on your needs and what you want to get out of it. Choosing a design/frame is going to help define everything else. This is dependent on your both your interior and exterior space requirements, the look you're going for, and your budget. Small geodomes are visually interesting and are relatively simple to build, or the traditional greenhouse look may be what you're looking for. Choosing this helps decide the construction material needed.

Construction Material

The two main construction materials for the walls and roof are lumber or metal conduit. However, lightweight PVC piping or steel are also options, depending on your needs. Choosing which one may depend mostly on your experience and your budget. Either material is appropriate, but most homeowners are more comfortable working with lumber. After deciding on the design/frame and the construction materials to use, the next step is to set up the frame and insulation.

In addition to the construction material of the physical structure, keep in mind the flooring material too. A system that easily drains and maintains an appropriate barrier between pests and bugs is ideal. This can range poured concrete with drainage, crushed stone with weed cloth covering, bricks overlaid on sand, or weed mats.

Insulation and Greenhouse Cover Material

Depending on your needs, which is partially defined by your geographical location, you can choose several options for the insulation. The greenhouse cover material doubled as insulation and your your walls, so taking into account the harshness of the weather is important too. The two main types of greenhouse cover material are solid corrugated polycarbonate sheets or different thickness polyethylene film. The thickness will depend on the level of protection required.

Conditioning the Air and Ventilation

Conditioning the air and small greenhouse ventilation are needed in some capacity, however, just a small greenhouse ventilation system may be enough to maintain the appropriate conditions for most backyard greenhouses. At a minimum, the ability to open a window or a door and leave it open can act as a form of ventilation. However, it may be necessary to include a physical window or vent that can be opened or close while also limiting bug and water infiltration.

Overall, you want the ability to control the environmental conditions within your greenhouse. This includes a blower, heating, or cooling systems. A simple thermostat can be used to control these, however, someone can also incorporate a more intelligent system if they need to in order to more precisely maintain the environmental conditions.

Other Considerations

The type of door you want may depend on your needs. Most backyard greenhouses will have a simple door that has the same insulating material as the walls. This is an easy go-to option. However, there are other options such as roll-up doors or simply an area where you can easily move aside the plastic insulation to gain entry and exit.

Depending on the style of the greenhouse, a guttering system may be needed. This helps maintain the integrity of the greenhouse by channeling the flow of water from rain to a specific area. Better yet, channel the water to a water tank for watering the plants.

Benching and tools are a consideration that you want to take into account when working in a greenhouse. benching allows for you to work higher on a sturdy structure so your plants can thrive. Having the tools available and placed in there is an organizational point that makes it easier for your to achieve what you'd like to. Also important are greenhouse lights. The greenhouse lights can aid in supplying light to the plants, aid in your ability to see when there is not enough ambient light, or both.

Putting It All Together

Start by laying you flooring which will be used for greenhouse. Erect the frame on top of the flooring. At this point, it may be best to include any electrical components such as lighting, fans, blowers, heating or conditioning components to the frame. Next, cover the frame and doors with the insulating materials of your choice. Finally, install any guttering system and the interior components such as benches, places for tools, and the like.

Fish Farming In Us And Canada

Posted on by

Freshwater fish farming is a Also known as pisciculture, fish farming is a method of raising fish commercially in a tank, pond, or enclosure. These fish can be raised to serve a variety of purposes but are usually used as a food source in one way or another. Below, we'll take a look at how this farming works in the US and Canada, what advantages it may have, what some of the most common farming methods are, and more.

Why is freshwater fish farming beneficial?

This form of aquatic agriculture is beneficial for a few main reasons.

Saves wild populations - Aquatic farming is a great way to use farm raised fish to supplement wild populations or otherwise protect and reduce instances of overfishing in wild fisheries and natural lakes.

Easily containable - Fish farms contain fish well and don't have many risks when it comes to domestic animals interfering with local species.

Ecologically friendly - In many ways, this form of farming can be ecologically friendly. Many fish farms today utilize green practices that don't have much of an impact on the environment. Very-high-intensity recycle aquaculture systems, for instance, reuse nearly 100% of the water that they use in their fish farms.

Economically viable - Freshwater aquaculture can be a lucrative industry that provides jobs for many people.

What species of fish are usually farmed in the US and Canada?

There are a wide variety of fish species that can be grown and thrive in freshwater fish farms and aquaculture facilities in the United States and Canada. The most commonly farm raised fish species are:

Grass carp Silver carp Black carp Common carp Nile tilapia Crucian carp Salmon Trout Roho labeo Wuchang beam Amur catfish Northern snakehead Milkfish

Which methods of freshwater farming are most commonly used in North America?

There are a few main methods of aquatic farming that are utilized in the United States and Canada.

Cage Systems - These fish cages are generally placed in places like ponds, rivers, bayous, and lakes. They contain and protect fish in a natural environment until they can be harvested.

Copper-alloy Nets - Copper alloys have recently become a material used in modern aquaculture. This is because they are antimicrobial and safe for the fish in their marine environment. These alloy nets are used to contain fish that are farmed in a natural or a man-made water source.

Irrigation farms and ponds - Irrigation farms and ponds utilize ditches and other areas that collect water to farm fish. These ponds and ditches can be natural, though usually, they are man-made. They contain buried pipes with headers in most cases and are generally lined with bentonite clay. In small systems, the waste products of fish are used to fertilize fields and crops. In larger systems, these ponds can grow water plants and algae along with fish.

Integrated Recycling Systems - These systems aim to reduce the use of water in farms for financial and ecological reasons. They function in many different ways but generally will involve the purification of water in a greenhouse or hydroponic bed.

Classic farming of fry - This is a form of a flow-through system that involves sport fish like trout being raised to fry and then released into the wild and re-caught.
