Particularly in large football stadiums with steep and fully covered stands the grass often does not get as much sun as is needed. To ensure that grass can grow towards the sunlight, time-intensive and costly maintenance methods, including infrared lighting, need to be used. In addition, some sports arenas are fully covered like BC Place (Canada) or the Astana Arena (Kazakhstan).
A football turf field on the other hand does not require any sunlight. It is therefore a good alternative to natural grass when there is not enough access to sunlight and financial resources are limited.
