These are the most advanced models of glazed reflectors in that the glass, in Pyrex or Borosilicate, which they are provided with, can be re-stretched at will. Through a clever system of "trap door" or "drawer", these reflectors adapt to the temperature differences that can occur in a grow room, depending on the season and the place where the "grow room" is installed

The advantages of a glazed and ventilated reflector:

- average gain of temperatures obtained: - 4/-5 °C with the same volume of extraction and the same light power (practical to limit the phenomenon of evapo-transpiration, during the hot periods of Spring or Summer);

- "safety distance" (distance from the lighting to the tops of the plants to be respected without the risk of burning the plants) to be divided by two. A concrete example: we recommend to place a 400 W HPS or MH bulb with an open reflector at a height of 30 to 40 cm from the tops. With the same lamp but this time equipped with a glass reflector connected to an extractor (of about 400 m3/h), the safety distance will then be reduced to 15 to 20 cm, effective in reducing light loss in relation to the depth of lighting. And, knowing that the horticultural light loses a third of its power, every 30 cm of height..
