This is a part of inside.
A normal camera can not take all area at once.
A special camera is used and show all area.
Left top is the door.
A set of double door are used.
Inner door is laserlite and outer door is shade cloth.
Inner door is opened except winter.
Air flows in through the shade cloth door.
Room is not tightly sealed. Many gaps are between laserlite and supporting timbers.
I try to minimize the pollination caused by insects.
Shade cloth seals all gaps.
