no substrate method question

I use an incubation room (thermostat set at 89.5 degrees), rather than an incubator-so the containers have to provide all the humidity. But with saturated vermiculite or perlite that is no problem.

So if the boxes have to produce all their own humidity why would you want holes so that it leaches out? In a sealed box all that good humidity stays in the box.
