My dahlia growing season is underway

Is anyone else getting their dahlias off to an early start this year? I had good success last year getting earlier blooms by starting the tubers ahead of time in pots and then transplanting them into beds after last frost. This year I'm getting a bit carried away with early starts.

I've run out of pots and now I'm converting misc 1 gallon jugs into pots. By the way, the big jugs of water are thermal mass to help hold heat overnight. When a really cold freeze in the lower 20sF is expected (like tonight) I cover the water jugs and pots with blankets and they stay well above freezing even though the temperature inside the greenhouse may dip a bit below freezing. (I don't have any kind of heater in the greenhouse, just solar heated water.)

The outdoor temps here dipped to right around 20F last night. Inside my unheated greenhouse it was a tender plant damaging 29F and a small freeze testing bowl of water froze a 1/4 inch thick. But happily under my protection zone of water jugs and blankets the temperature stayed at an acceptable 41F degrees. :) Many of my early start dahlias have leaves out already and would likely have been badly setback without the extra protection.
