AIR

ALBUCA 



AIR (Giving). This is a term used by gardeners for 

 ventilation, or opening the top sashes to let out the 

 stagnant air and admit fresh, by giving ventilation from 

 the sides or lower portion of the houses ; modern growers 

 rarely give much side ventilation. On consideration, 

 any one will agree that it is not a natural state of things 

 to have a cold draught from beneath the plants where they 

 are grown on stages.
