1. Why the dome shape?
>> Great question! First of all the shape is beautiful, in addition it is functional: it allows to obtain the maximum volume for the least amount of material. The dome withstands the high winds and the weight of the snow. And above all it always has the same exposed surface facing the sun which allows to enjoy the slightest ray. The dome takes heat regularly all day long, so it avoids the heat spike of traditional greenhouses. Finally, its globe shape reminds us of the planet we live on, the earth, our foster mother.
2. Can it really allow gardening all year long?
>> Most emphatically yes! The dome has two seasons: hot and cool. In summer it allows the cultivation of all plants loving heat: tomatoes, peppers, eggplant, zucchini, squash, cucumbers, etc ... In winter all the most robust: lettuce, curly, corn salad, spinach, chard, card, peas , beets, cabbage, leeks, the whole family of onions, and aromatic plants. During the winter cold, growth slows down and may even stop - the dome may freeze - but as soon as the sun shines, the shoot resumes. The unique combination of dome features allows the cultivation of green vegetables, fruits and flowers every day of the year!
3. Why a water tank?
>> The water tank is the POWER RESERVE of the dome. In winter, it absorbs the heat of the sun during the day and restores it at night, moderating the low night temperatures. In summer, it acts as a cooling mass, preventing overheating of the dome. It can be used for growing aquatic plants or for raising fish.
4. How many people can the dome feed?
>> Depending on your gardening skills and soil fertility, you can harvest about 12 kilos of vegetables per square meter per year. Thus, a dome 6.70 meters in diameter (35.3 m²) can produce more than 400 kilos of vegetables per year. On average we consume about 100 kilos of vegetables a year. Most people complete the dome with an outdoor garden.
5. Will it never freeze inside?
>> The dome can freeze during periods of prolonged cold without sunlight. Some gardeners add an auxiliary heater that, even tiny, works well considering the insulation of the dome. However, most cold-resistant plants continue to grow as soon as the sun comes back. See our suggestions for choosing the location of the dome, to optimize the thermal efficiency of the greenhouse.
6. Is it a lot of work?
>> The main job is to pick up the production from the greenhouse! Most people say they spend an average of 4 hours a week in their greenhouse. It's a real pleasure because the dome is such an attractive place. The problem is to stay away! The automatic aerators are there so that we do not worry about overheating, we can return home late on a cold night without worrying that the vents have remained open!
7. And about the building permit?
>> The dome is considered a temporary structure because it has no foundation and can be easily dismantled. Even if you move you can take your dome with you! Read "Building Permit"
8. Does he need foundations?
>> No, the dome is light and can rest on a bed of gravel. However, it must be anchored in the ground, which can easily be done with concrete reinforcing bars, the length of which depends on the hardness of the soil. We have prepared a short presentation of the "Foundation Options" which presents the possible types of foundation of the dome.
9. Is everything included in the price of the dome?
>> Yes everything is included. The dome is delivered in "kit", designed to be mounted by its owner. Only the gravel on which the greenhouse rests must be provided by the owner. We can also provide a team that can install it.
Indoor planters, heating or watering are not part of the kit and can be provided on request.
10. Are parasites and disease a problem?
>> Each greenhouse is a wonderful growth area for both plants and insects. We recommend bio methods to counter pests. There are many excellent books on this subject. We recommend "the gardening companion in a greenhouse", a book by Shane Smith, which unfortunately exists only in English for the moment (Greenhouse Gardeners' companion), also Cultivate under greenhouse and Joyce Russel's plastic tunnel, which exists in French version; we can also advise you on some of the most common solutions. However vigilance and cleanliness are the two best weapons.
