Difference between 帐篷 and 大棚？
大棚 could be:


Commonly short for 蔬菜大棚, a warm house for growing vegetation, usually very large. 

sometimes, a tent-like structure, not fully enclosed, often used as a mobile kitchen and dining area.




帐篷 is more of a closed tent which has a roof and has cloth walls all around it. It's built for people to sleep in. Campers and refugees may reside in 帐篷s.
