Glass and plastic are commonly used to protect plants against the weather, but also to hasten or delay some crops.

The bells

The bells

• Traditional models are glass, one piece. They are suitable for the protection of a single plant at a time (they are placed in a pleasure garden on a fragile plant, in winter, or in a kitchen garden on a melon plant, for example). To allow ventilation (essential), lift the bell slightly with a small wooden wedge or stone.

Protection against the cold: protection

• The plastic bells today replace the beautiful glass bells of old, unfortunately fragile. These accessories, lighter than glass bells, must often be held on the ground by a small stake so as not to be blown away by the wind.

Protection against the cold: garden

The English bells (or continuous bells) are mainly intended for the protection of the lines of culture. Open on each side and placed end to end, they form a kind of tunnel. Made of glass or transparent plastic, they are held by a metal frame and are equipped with a handle, which facilitates their transport. Glass plates are provided for closure at each end.
The bells are practical because they are easily mobile: they can easily be transported from one board to the other, depending on the requirements of the culture. They save two to three weeks for the growth of most vegetables in the garden.

The chassis

The chassis

Made of a box covered with glass plates, a frame can accelerate your vegetable production by three weeks. It is used to obtain early plants for the pleasure garden. The frames are usually installed in the vegetable garden, but they are also used in the pleasure garden and even in the orchard, for the fruit trees (cuttings).

Classic chassis

Classic chassis

The classic frames are made of a wooden or metal frame, with windows, which rests on wooden sides. These sides must be designed in such a way that the glass plates are inclined in order to take full advantage of the sun's rays. Wooden chests are handy because they can be moved or even removed. A wooden frame chest must be treated with a special product (water repellent) against moisture and fungicide against mold. A classic frame is 1m x 1.30m (but it can be wider).

The masonry frames

The masonry frames (mostly used by professionals) receive glazed panels sliding on slides and removable.

Some current chassis

Some current chassis

Some current chassis largely use plastic. There are small models made of a sheet of plastic frame whose sides can be raised easily depending on the temperature (these chassis form tunnels by juxtaposition). They are practical and discreet (90 x 115 cm for 8 kg) and are well suited as a frame.
A good solution in all gardens: kits. Many manufacturers offer wood and glass or metal and glass. They are easy to assemble and disassemble (and cheaper).
