Reflecting film for greenhouseIn greenhouses, mainly solar greenhouses, reflective films might be used.
Reflective film was a material that played a role by reflecting light. A common reflective film was aluminum foil. Its use in the greenhouse had certain characteristics and requirements. For example, the reflective film could be placed on the back wall of the solar greenhouse to improve the light efficiency, but this was a passive method. It needed sunlight to work. Compared to the fill light, the effect was not direct and obvious, but the cost was lower, so it had a certain value.
There were also precautions during use. For example, if the reflective film used for apples was used in a relatively closed place in the greenhouse environment, it could not be sprayed with water. Because the reflective film in the greenhouse was laid out (different from being rolled up before laying), due to the exposure of the aluminum to the air, moisture would be emitted after moisture. As long as it was not a serious moisture situation such as heavy rain or soaking in water, it would generally not de-aluminum, but it was still necessary to avoid spraying water, which may cause moisture.
In terms of greenhouse vegetable management, if it was continuous low-temperature rainy (snow) weather, under the premise of ensuring that the temperature in the greenhouse would not cause the vegetables to suffer from cold damage, when the heat preservation was removed to increase the light time, a reflective film could be hung on the back wall of the greenhouse to increase the light in the greenhouse; If the low-temperature cloudy day lasted for a long time and the conditions were met, a fill light could also be installed for artificial supplementary light.

i Read up to chapter 607 very disappointed with the current arc (chapter 564 onwards) the story was great up to chapter 563. the novel was very mysterious. every new secret makes you want to read more chapters. the cheat is acceptably he is strong and able to dominate the human opponents but the monsters are very strong. he slowly can fight them after learning the history of the "world" plus his cheat. there are monsters and gods. then at chapter 564 the story shifted. let me describe the change. the novel feels like two greenhouses . one inside the other. the inner greenhouse where the main character started is like a very violent jungle. up to chapter 563 the story was like a fantasy. at chapter 564 the main character managed to leave the inner greenhouse into a bigger greenhouse. the genre became post apocalypse. from a survival jungle into a well maintained garden. there was no ferocity in the enemies. they are even comically pathetic. the main character feels like he forgot his time sensitive mission after moving to the outer greenhouse. most of the mystery is answered here. the grandeur of the setting shattered for me. all i can say is... They had us in the first half not gonna lie
