Plants need gravity, and many seem to need a rotation as well. The growing tip of a plant (apical meristem) grows in a spiral, which when you think of it is a pretty clever way to continue the construction.
Flanders and Swan sing of the "left-handed bindweed and the right-handed honeysuckle" [Forgive the lack of literary accuracy.] and it is true that by rotating a plant slowly counter to its natural spiral, this damages the plant growth.
Experiments of the nature you suggest have been done in the space station.
what happens when a plant does not have enough water?

Plants use gravity to help determine the direction in which to grow their roots and stems. This response is known as gravitropism - roots grow downward with gravity, while stems grow upward against gravity, a process mediated by plant hormones called auxins.
Most plants grow up, or away from gravity. Even vining plants will first grow upwards before they grow too long and start to vine. So, if a plant were subjected to a change in gravity...say, hung from an upside down pot...it would change it's growth direction to again grow away from gravity, growing upwards.
the gravity increases
yes it has gravity, that's how the plants orbit it.
Geotropism, the tendency of some plants to grow straight up, against the force of gravity.
it's gravity increases
Nothing happens to gravity. It remains the same as it is everywhere else on earth.
More mass --> more gravity.
Your distance from plants does not affect gravity. Gravity is a force of attraction between objects with mass, such as the Earth and everything on it. Plants do not have a significant influence on the force of gravity acting on you based on how close you are to them.
