Polytunnels for plant storage in winter represent an effective protection against low temperatures. Cold conditions may appear in early spring as well as in autumn, leading to some damage for plants or even death for the most sensitive ones. If located where heavy snowfalls and cold winters are the norm, a greenhouse becomes a necessity. Often associated with cultivation of vegetables and fruits, they can also act as storage rooms for pots, plants and seedlings.
Polytunnels for plant storage in winter
By storing potted plants in a polytunnel, one provide them with even access to light. Transparent foils transmits 95% of the sun’s rays, evenly diffused into the greenhouse. This enables production of more green mass. When kept in buildings with window, light only reaches parts of the plant. This leads to a number of deformations that interfere with growth. Importantly, under cover, a micro climate is created, favoring further development.
In winter, potted plants are exposed to frost, snow and rain. They may get crushed or break from icy conditions. These factors have negative consequences. When water gets in a container and then freezes, it can cause the pot to break. Root damages are even worse consequences. The best way is to transfer plants inside a greenhouse. A foil, secured with clips on a structure made of pipes and profiles, constitutes an effective barrier, except for light. Therefore, many of the negative factors are prevented, allowing flowers, shrubs and decorative trees to grow optimally.
Ventilation in a greenhouse
When temperature decreases in the greenhouse, humidity is also reduced. Then plants are exposed to drying. It should be remembered that watering is imperative even in winter. Although not needed in big amount, any deficiencies may later affect health. In contrast, as soon as it gets warm, plants wake up after hibernation. You will feel and notice a higher humidity rate. To avoid the appearance of mold and disease, ventilate the installation. Some polytunnels are equipped with side ventilation. Both sides feature openings, which are activated manually with cranks. Raising them causes air circulation, removing any excess moisture outside the facility. It works similarly with high temperatures. When a heat wave hits the area, the risk of overheating increases in the greenhouse. Tunnel ventilation then contributes to the removal of this harmful atmosphere.
Modular steel construction
Polytunnels for plants in winter are modular structures, designed in order to be modified at any time. When additional space is needed, gardeners can order parts to increase storing space. Steel constructions guarantee solidity and durability. Frame elements are connected with screws and clamps and anchored to the ground, so greenhouses can withstand difficult weather conditions. As far as solid constructions are concerned, pots can be hung on the frame for more space. Safely stored, plants will remain there until the mild season returns.
