45 degree's to cold for vegatative growth?

just wondering....It has been in an environment for about 4 weeks at 70-80 degree's and moved it to a new location in the attic which is 45 degree's. can it still maintain vegetative growth in these temperatures.

Yikes...

How long has it been in the attic?
How can it be 45 degrees up in the attic if the lights are on? What kind of lights are you using..

I have heard people say that growth comes to a near stand still at 56 degrees. You may become the in house expert on this topic...

cheers

well just for like 2 hours maybe.... putting a space heater, they are running CFL's. just 1 though. on 1 plant.
