I just verified that my plants show 'not growing now' when its night time, even though they are in a hydroponic basin and beside a sun lamp.
I tried changing the sunlit requirements to 'dark' but still did not work. This was with no mods and with Tmod for crops
this done for balance reasons.
no crops grew constantly, if you remove light at night they still will die.
Nice! Thought that was the reason. Thanks
