The Plantagon greenhouse
Plantagon is a vertical greenhouse for the urban farming environment
Plantagon Greenhouse report
2.1 Urban agriculture with economic growth
Today’s greenhouses are situated far outside urban areas. The whole idea behind Plantagon is to place it in urban areas, close to the consumers, which will reduce handling costs by up to 80 percent.
Plantagon estimates that about 40 to 60 percent of an urban consumer’s food budget goes to pay for transportation and storage. Vertical greenhouses can deliver fresh, healthful organic produce directly to the consumer at a lower price.
The concept is simple and appealing in these days of awareness: fresh, ecologi- cal and cheap vegetables. no middle hands, no yesterday’s food.
2.2 Join the positive spiral
The core of the vertical greenhouse is a spiral-shaped transport mechanism that slowly moves hundreds or even thousands of soil-filled planting boxes upward, as the plants grow. With the boxes resting on a pair of rails that cork- screw through the entire volume of the structure, a third rail carries a device that continuously cycles from the top of the spiral to the bottom, nudging each box a few centimetres upward. When they reach the top, the mature plants are pushed out onto the harvest platform, and new boxes of soil and seed are pulled in at the bottom.
2.3 Ten times more efficient
The spherical shape of The Plantagon greenhouse is designed to maximize the amount of light available for plant growth. The unusual form adds to construc- tion expenses, but we say that the doubling or even tripling of yields, makes the structure more than competetive with traditional greenhouses or surface agriculture. With a ground footprint of 10,000 m2, a vertical greenhouse equals 100,000 m2 of cultivated land.
Compared to traditional growing, The Plantagon automated greenhouses are estimated to
• be 5 to 10 times more efficient to maintain,
• increase profit per square meter 2 to 4 times,
• produce 3 times more crops.
The idea is simple; to use the full volume of the greenhouse, growing in stories. The less simple, but highly innovative, idea is to adjust the construction, shape and technology of the building to what the plants need. after maximizing what is good for the plants, advanced technology is used to help us take care of the plants in a rational way.
2.4 Small, big or enormous?
The greenhouses will come in three different varieties:
1. smaller greenhouses, in the immediate proximity of end-consumers in the
2. Bigger constructions outside city centres, where the client base mainly
consists of wholesalers and restaurants.
3. enormous plants, away from the city, providing large grocery store chains
with fruit and vegetables.
