During the night, the sun goes down. Thats a pretty fundamental problem here, in that during the day, plants can of course get energy from sunlight through photosynthesis. But during the night, when the sun goes down, their source of energy disappears and they had to come up with some way to compensate for that so the plant metabolism and growth can go on during the night. So, the way in which plants solve this problem is that during the day, they store some of the energy which they get from sunlight in the form of starch and during the night, this starch is broken down. And the observation was that the rate at which starch was broken down during the night was more or less constant during the night. If you measure the amount of starch as a function of time during the night, it kind of goes down as a straight line. Some of the best growth i see growing weed over 25 years is during the night cycle
