The modern commercial greenhouse standard height in north america is 16 feet for floral crops and 21 feet to 24 feet for vine climbing produce but don t quote me for too long on that one.
													
																	Greenhouse roof height. 
									
	
		
	
																	Taller greenhouses allow you to produce more crop in the same footprint. 
																	Greenhouses built during the energy crisis of the 1970s usually had an 8 foot height to conserve on energy. 
																	However a tall greenhouse allows warm air to rise away from plant foliage so that temperatures remain relatively balanced at the floor level. 
																	You can also change the height of the south facing wall to alter the angle. 
															
													
									
	
		
	
																	A greenhouse height of approximately 13 feet is. 
																	We recommend choosing a practical height usually a maximum of 9 11 for residential solar greenhouses and then using the adjusted rule of thumb to ensure that the glazing meets the minimum pitch for light transmission. 
																	To 16 ft tall greenhouse that roof structure is much further away from the plants. 
																	In fact the optimal height for a greenhouse appears to be 13 feet which allows for better airflow and temperature regulation with most plants getting exposed to mild but consistent temperatures around the bottom of the greenhouse.
