You need to put them at least in a ft. of water OUTSIDE in your pond. You don't want them growing now in your greenhouse now....they will get huge , , be difficult to pot in the spring, and it might affect the blooming.!
You can put them in the pond where the water is at least a foot deep and just place a rock on them to keep them from floating back to the top and freezing. In the spring you can retrieve them and pot them up. Just be careful and not break the growing tip on the lotus....it is very FRAGILE ,and if broke ,it will not grow a new one.
