My question is why?
You don't play indoors when you play matches. Practise in the conditions you play in.
Seriously? Frozen pitches, snow, to save the pitches if they are getting heavy. You might have sufficient drainage, but that isn't going to stop the pitch cutting up if it is compeltely saturated. Plus, why make your players train in extreme/adverse conditions and risk injuries for the sake of training "in-situ"?
