@Bubbles, they are discussing bubble wrap in the Greenhouse forum. Seems the pool covers are the strongest and work well. Go over there and see what they have to say. I just discovered my heater timer went kaput tonight. Just when I had stopped obsessing over checking the GH temps. I have it set on Med. for the next 36 hours without a timer. Then tomorrow I will bump it up for the freeze. I know the plants are pouting even at 55ยบ.
