The only problem is that even with the roof open 24 hrs a day, because of the way the architects designed and oriented the stadium, the amount of sun that the grass received still would not be adequate for it to be optimally maintained (and that is not even accounting for long stretches of cloudy days). That's why it requires frequent transport of the pallets out of the stadium, or replacement.
