that link for DIF does not include testing for cannabis, so it could very well have no effect just like a tulip. Personally I have never noticed elongation of the plants when temps got low, but then again I have never been looking for it.

Even though I haven't seen any scientific papers showing the effects on Cannabis, I still wouldn't disregard the effects it could have. Stretch is our enemy, and Ill do everything I can to reduce it. Even if it had little to no effect, having a higher ADT(average daily temperature) by keeping night temperatures higher will benefit the plants.

with lights off your plant temperature is still high canibus holds heat longer meaning it slowly releases the heat how i know this is
a X - cop in narotics mention how easy it is to find out door crops they fly out at midnight and on infrared they can spot heat signatures a mile away from the plants he said that a spruce tree will cool down faster then a pot plant

With this being said if your room gets down to 50 - 55 degrees really how cold is your plant if its still releasing heat 5 hrs into darkness my next purchase will be a infrared heat temp guage i am very curious on what the plant tempurature really is and how the temp of plant drops per hr of darkness vs room temp

hahaha i feel like a mad scientist now lmao

I have an infrared temp gauge I use in my grow room, and it doesn't take very long for leaf temperatures to drop after lights out. Ill gladly check it for you tonight and post results.

Maybe he read this thread about growing MJ by UB.

"Temperature and the importance of day/night differential - In general, a 85/70F (32/16C) day/night temp is best for most hybrids for maximum carbo production. What's really important is a good drop in temperature at night, of at least 15F/4C. If night temps are too high, the plant will use up the carbos manufactured during the day to the process of respiration as opposed to plant cell division/elongation (tissue production)."

This is my understanding as well.
