It relates to a tray-rotating chamber for growing crops that can be maintained in optimal conditions according to crops to be grown.

In recent years, in a situation in which agricultural land or clean areas are decreasing due to the expansion of various factory facilities and housing construction due to industrial development and population increase, agricultural land where crops are grown by the use of chemical fertilizers, etc. As a result, the cultivation of clean crops and various plants is becoming more difficult day by day, and the plants growing in this environment are also not growing properly.

Accordingly, research in various methods for efficiently cultivating various crops to be consumed as well as a large amount of food shortage is being conducted around the world.

In this way, the cultivation method including food or crops is divided into a method of cultivation in the open field and a method of cultivation inside a facility.

Outdoor cultivation is a method of cultivating crops according to natural conditions in paddy fields or fields, and facility cultivation is a method of cultivating crops using a plastic house or glass house to create different conditions from the natural conditions inside the facility.

In particular, the cultivation of crops inside facilities such as a plastic house or glass house is evolving into various forms because it can be grown all year round, regardless of the season, and desired crops can be grown according to necessary conditions.

On the other hand, in recent years, various methods such as stacked type, caterpillar type circulation type, or storage in a chamber, etc. have been used to increase production efficiency in preparation for a limited area. A chamber-type crop cultivation facility that is convenient to control humidity, etc. is a trend in the spotlight.
