Anyone else worried about the sudden cold snap?

[FourOaks]

Just wondering if anyone else is making preparations for their GH heating needs? Earlier today I put 2 propane heaters in mine. Both are radiant, which I understand Blue Flame is better. Right now, I have no choice. I already had the heaters, just in case of a power outage.

One heater is a Dyna Glo brand, disc style propane heater. The other is a Mr heater "Big Buddy" heater. Both are running off of individual 20 lb tanks. Both set to "medium". I have one at either end of the GH.

All small seedlings in the 4 inch pots were moved back into my house. The 88 transplanted tomatoes obviously have to stay in the GH. Hopefully none succumb to the cold weather.

Supposed to have overnight lows near freezing. Tonight, 39. Next 2 nights 34. Last year we had a similar cold snap come along, I used heat lamps to keep everything going. Lost only a couple of plants.
