Miso-tech's Agron Bubble wrap helps it.

Agron, as a sheath that dramatically increases energy efficiency with its strong thermal effect, which is already specialized in insulation and cooling, cover it with another layer of bubble wrap used as single material!

With a heating rate of more than 42.6 percent, it reduces crop stress caused by temperature differences and eliminates coldness damage by water
 
How about in summer?  
It's that much cooler because Both Agro and Bubbled Wrap block heat.

First, the basic material Agron is strong.

 And instead of direct sunlight, scattered light makes the crops grow better.  

With 80% of light transmittance and 30-40% of scattered rate,
quality crops can be grown without damage by high temperature or sunscald

While maintaining optimal temperature at cheaper cost for four seasons, light and easy to install, durable and long-lasting house.
