The ebb part was for the OP. I should have @ him in.
Interesting theory, well, maybe not so much......I got questions for you.
How big a pot.
How much at feed and at straight water are you applying?
Where did you come up with this "theory" of watering at night? I understand your "idea"...... yet the application is not really the best plan....
Drop us a pic of a plant....
I make my plants into race cars and never have to "water" at night. I gotta see if your over watering.
If your feeding enough at lights on - to carry it till the next day at lights on. You get no loss of anything.
You seem to have a knowledge of book learning, and yet you don't seem to understand night and day functions of the plant exactly right.
You also let the "Light saturation point in C3 plants", slip over your head.
Your idea is no more then an incorrect logic experiment. Your not increasing shit and your not really increasing turgor pressure at night by watering again......Wonder what the condition of your roots are...
I'll bet dimes to dollars he thinks he has. I'll bet pennies to dollars it's far from true.
Personally, Hell no I wouldn't flood at night. Your not accomplishing anything!
In fact Budley, if your flooding at night, and your seeing no increase in anything.. Goes to answer your question if he's gotten an increase in his growth rate ...... eh?
With out the sun and photosynthesis occurring, the plant, any plant, has a natural loss of turgor at night. Increasing available moisture to the soil/roots, does not increase the turgor pressure within the plant.....at any rate your idea is used for.
Bottom line to both of you.
If the plant gets enough moisture from the media. It's not going to loose turgor (or hydrostatic) pressure for anything but natural reasons, that can be explained by plant biology....
If what you propose were true. You would have one of the most stretched out lanky plants, and how is that a good thing?
Why? Because turgor pressure is responsible for apical growth in plants - Terminal bud (the central main over branching) and root tips). This would be (if anything) the growth increase he would see.
