Instead of a rooting room, the trayed up bulbs may also be stored on a standing ground. For more information, refer to Tulip, Standing ground.

This is recommended until mid-November after which it becomes difficult to maintain the right temperatures.
During frost, cover the trays on the standing groud with straw (in severe frost also with bubble foil) to prevent frost damage.
