Plants that do not sleep on nights before they need water?

I notice with my not watering until the plant droops method some plants will stick up there leafs the night before it needs water. I will water this plant tomorrow moring or afternoon. The same night it gets water they will sleep like the others next to it are.

I think the roots know they are about out of water and are busy looking for water not letting the plant sleep.

Okay I am stoned for sure. But why else would a plant stick it leafs up in pitch black everytimes it needs water the next day? All my plants will do it. But the diesels show it the most.

Whats your thoughts?

hmmmm interesting....you always get me thinkin'....I'm gonna pop a fuse haha......IDK, I don't really pay that much attention to em' at night.

Here is another plant sticking it leafs up at night. I will water this in the morning for I know it will need water the next day for sure. I see this as max growing. Again I have no proof just thinking.


Another plant sticking up at night.

hmmmm.....yea I'm gonna have to start paying more attention to what mine are doin at night. What the plants do at night has caught mu interest recently anyway, that's why I'm doin' a little indoor under that gas lamp thoery light schedule, which stands on the idea that the plants grow at night mostly, not during the light cycle. Also, I know your onto something getting the watering down to when the plants WANT IT , not when we THINK they want it.
