If your g/h is insulated by bubble wrap, your Citrus can be draped with fleece....it won't draw moisture as much as a sheet or blanket would. Don't bubble wrap the plant...that is only necessary if the pot is outside and needs to be protected and in that case,you bubble wrap the pot, not the plant.
Remove the fleece every day and put back at night if temps are going to fall drastically.
Ventillation is essential and make sure you put your citrus outside for the greater part of the year. They don't make happy House Plants.
