Elephant Ear Experiment

I'm going to plant Elephant Ears in my shade garden.  However, they cannot go into the ground until it is warmer, probably sometime in April.  I don't want to wait that long to have them come up, so I'm starting them indoors in pots.  I found plenty of internet sites saying go ahead and start them indoors, but nothing about how big of a pot to start them in.  So, yesterday I bought four elephant ear bulbs, and decided to try starting them in gallon milk jugs.  I have a constant supply of them, and it's a good way to recycle.  So, I cut the tops off, mixed potting soil with some peat moss and threw in some bulb food and planted my bulbs.  We will see if this work outs.  Hence, my elephant ear experiment.
