Concept Ideas

Polyethylene Film Greenhouse covered in sheets of polyethylene film Pros- Transmits and diffuses light fairly well, easy to install, photodegradable Cons- Not very durable, extremely expensive

Recycled Grocery Bags Made of material similar to polethyelene Could set up recycling system to gather used bags and manufacture them into a large sheet to cover the greenhouse Pros-Same benefits as polyethylene film, better for the enviroment Cons- Fragile, would be difficult and expensive to set up recycling system

Hemp Plastic Hemp can be used to create a plastic that could cover the greenhouse Pros-Durable, biodegradable, can be made with local materials Cons-Not very translucent, doesn’t diffuse light well, expensive to make

Bottle Skylight- Chosen Concept Greenhouse covered in cheap, well insulating fabric, wood or industrial hemp plastic Two liter bottles filled with water and bleach attached to greenhouse supports Holes in covering to snugly fit around the middles of the bottles Half of the bottle is above the covering and half is below Sunlight hits the top of the bottle and is distributed all over the inside of the greenhouse

Transmissivity/Light Diffusion The bottles themselves will transmit the light very well. The covering will be opaque and will not transmit the light as well. However, the bottles will diffuse the light and spread it all over the greenhouse.

Thermal Insulation The greenhouse will have very good insulation compared to other concepts. The covering will help hold in the heat. This will help keep the greenhouse at a good temperature and provide a consistent environment for plants to grow.

Longevity Our method allows us to cover the greenhouse with a durable material, as opposed to flimsy plastic like some other methods. It will hold up well to the elements. This will allow the greenhouse to be used for years.

Affordability Our concept will be extremely affordable, particularly compared to concepts using an expensive plastic covering. The bottles will be recycled and essentially free. The covering can be made out of the cheapest material available, as only the bottles are needed for the light.

Other Benefits Environmentally friendly, can be made from recycled materials Easy to assemble and repair Potential to look good, depending on the covering Doesn’t require additional chemicals for protection, like rice bags would Group members- Amy Maffei, Joe DeArmitt, Garrett Kolmer
