As I never got a reply in https://www.rollitup.org/advanced-m...ardening-tweeks-pointers-200.html#post9899937 I thought I would start a new topic and see if anyone else has some tricks or suggestions.
My plants are not doing that bad and I don't have the luxury of a huge day/night temperature difference but would love to hear what you would do in a similar situation.
I run my lights at night (7pm to 7am).
Night time temperatures are on average 78 to 86 (with lights on).
Day time is usually around 85 to 94 (with lights off).
Small little grow for personal use only.
My lights are as follows:
1x 400watt hps
2x 105watt cfl
Extraction is a single 8" inline fan (around 800m3 an hour), pulls all the air out of the room about 4 times a minute.
I put the larger fan in to keep air moving out as fast as is possible for maximum possible c02 in the room, there is no way with my ambient temps that I can add c02 to the room as it will easily go up to 104' without constant air extration at an extremely fast rate.
If you would like to see the room:

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).
