Maybe we could do something about that.
Even though this document is on chrysanthemum's. The information that is contained inside relates to other plants. I've been searching the web for an document to post up and the best I can find is here http://aob.oxfordjournals.org/content/90/1/111.full.pdf
It all has to do with internode and stem length. also has if I remember correctly from my studies, anything drastic change within 10-15F WILL show symptoms of mild shock its system. same goes for the root system when you shock it from either warm or cold water.
Going back to what Uncle Ben had said. I would strongly disagree.
Plants don't do so well when the root system is cold. Matter of fact anything under 50-60 and the root systems metabolic uptake starts to cease up. When I say stay within 10-15F from your day/night, Even human's burn their own bodily nutrients to get the temperature to the level we need it at. Example: its 950F out and your you drink a cup of ice cold water, your body will now burn calories to get that ice water to the temperature your body is set at. So that being said, if your day is 75F and your night is 55F your plants priorities will be set to adjusting temperatures so it can run it's photosynthetic process and NOT on "growing" or "flowering" like you want them too.
If anyone has any questioned on this. just google "biochemical processes's of plants" and look into plants mechanisms for heat and cold tolerance and read about a plants metabolism when related to hot/cold.
Hope We Helped
