Glass greenhouse
1, glass greenhouse light transmittance than the PC solar panel greenhouse high, excellent light transmittance, about 90% , glass greenhouse overall aesthetic degree is good.
2. The use time of glass greenhouse is longer than that of PC solar panel greenhouse. Glass greenhouses can be used all the time without human damage, but PC solar panels are generally 10 years of solar panel materials, good can reach 20 years.
3.better thermal resistance and UV resistance, wear resistance, life up to 25 years.
4. The coefficient of expansion and contraction is low.
5. easy to obtain materials, low prices

Plastic greenhouse
1. improve the temperature and humidity. The air temperature in plastic greenhouse can be increased by 2 ~ 5 ° C, 6 ~ 8 ° C and humidity by 7% ~ 13% .
2. Easy control of environmental conditions. Seedlings can be protected from wind, frost, drought, air pollution and other hazards, conducive to the control of temperature, humidity, ventilation and other conditions.
3. The seedlings grow quickly and neatly. Generally, the height growth of seedlings is 1 ~ 2 times larger than that of the same age field seedlings, and the coarse growth is about 1 times larger, and the growth is uniform.
4. Simple to build and low cost.

PC board greenhouse
1. strong impact resistance, PC board impact strength is ordinary glass 250-300 times, how to knock will not be bad.
2. The thermal stability, in the temperature range from -40 ° C to + 120 ° C, will not cause deformation and brittle fracture.
3. portability, light weight, easy to carry, drilling.
4. It is easy to form, not easy to break when it is cut off and installed, and can be directly cold-bent, so it is simple to construct and good to process. Anti-fog drop (also called anti-dew Drop) , to the greenhouse heat preservation value of good protection, will not be due to the temperature difference formed by fog Didi drop caused by plant damage.
