Hearing Lu Jueyu's words, Liu Hua said, "Jueyu, even with a cover, summer crops won't survive the cold weather. It's better to plant winter crops."
"Sister Liu Hua, we plan to install a heater to keep the temperature inside the greenhouse warm enough for the summer crops to survive," Lu Jueyu said.
When Pan Meijia heard this, she asked, "Third sister-in-law, are you going to install a heater similar to the one used in Kang beds?"
Although Lu Jueyu had been talking about her machines, Pan Meijia's words gave her an idea. Since they needed a cover story for using her machine, why not build a large heater outside the house?
This way, they could have extra stoves and a logical explanation for how they kept the greenhouse warm. The machine could then be used to control the temperature during summer, allowing them to plant winter crops.
