CATDOLL : CATDOLL: How to build a constant temperature greenhouse?

If you want centipedes to grow quickly, you must change their low-temperature dormancy living characteristics and cultivate them without dormancy.

If dormancy-free breeding is to be carried out, a constant temperature greenhouse suitable for centipede growth must be built first. The constant temperature greenhouse should be built in a secluded place away from the use of pesticides. In order to achieve the purpose of winter insulation, when building the wall, a double-layer inner and outer brick wall is generally built, which is commonly known as "two-four socks or walls plus one-eight walls". The middle is filled with perlite, vermiculite, cotton and other insulation materials, and then the surface is smoothed with cement or lime. The greenhouse generally has six windows, three high and three low, to facilitate ventilation. Practice has proved that only by building such thick walls can the greenhouse maintain an ideal temperature in the severe winter season. In the north, such as Shaanxi, Gansu, Xinjiang and other dry areas with little rain, a vegetable cellar-style constant temperature greenhouse can be built to use the underground thick soil layer to maintain a suitable temperature.

In the coldest days of winter, the indoor temperature must be kept above 20℃. If it is lower than this ideal temperature, it will be difficult for centipedes to grow quickly. According to the terrain, the greenhouse is generally 10 meters long and 5 meters wide, facing north and south, which is easy to get light and heat. The building materials of simple greenhouses include red bricks or cement bricks, bamboo poles, wooden sticks, plastic or bench film, cement, lime, straw, etc., which can be purchased in general cities and towns.
