Films, sails and growth covers, as well as forcing and vegetable gardening films play a role as a growth accelerator. They create a microclimate favorable for seedling germination or seedling growth for a gain in early crop placement and harvesting. The greenhouse effect obtained indeed causes an increase in temperature and the maintenance of an ideal humidity under the film. These films also protect crops from bad weather (hail, wind), insects and birds. Benefit: The growth veil is the thinnest of the range. It is placed on the ground, directly on adult crops or recently sown, without straining it, fixing it with staples (or covering it on each side with stones or logs). Features: 2 m x 8 m, 16 m². Depth: 800 cm.
